Soft tissue necrotizing infections are a significant cause of morbidity and mortality. The aim of this study is to present a patient with necrotizing infection of abdominal wall resulting from the rupture of a retroperitoneal stromal tumor.
PRESENTATION OF CASE
We present a 60-year-old Caucasian male patient with necrotizing infection of abdominal wall secondary to the rupture of a retroperitoneal stromal tumor. The patient was initially treated with debridement and fasciotomy of the anterior abdominal wall. Laparotomy revealed purulent peritonitis caused by infiltration and rupture of the splenic flexure by the tumor. Despite prompt intervention the patient died 19 days later. The isolated microorganism causing the infection was the rarely identified as cause of infections in humans Pediococcus sp., a gram-positive, catalase-negative coccus.
Necrotizing infections of abdominal wall are usually secondary either to perineal or to intra-abdominal infections. Gastrointestinal stromal cell tumors could be rarely complicated with perforation and abscess formation. In our case, the infiltrated by the extra-gastrointestinal stromal cell tumor ruptured colon was the source of the infection. The pediococci are rarely isolated as the cause of severe septicemia.
Ruptured retroperitoneal stromal cell tumors are extremely rare cause of necrotizing fasciitis, and before this case, Pediococcus sp. has never been isolated as the responsible agent.

Cystic ovarian teratomas comprise 20% of all ovarian neoplasms, and are commonly encountered in patients between 20 and 40 years of age. Although these cysts are usually asymptomatic, we present the case of a patient whose cyst resulted in pruritus and abdominal pain. Based on a MEDLINE search of the literature, we believe this is the first case report of a twisted ovarian cyst presenting with generalized pruritus.
A 35-year-old Sri Lankan woman presented with lower abdominal pain of one day’s duration with vomiting and generalized pruritus. She had no history of allergies and was not on medication. Upon a physical examination, our patient was found to have an acute abdomen, localized peritonism in her lower abdomen and tachycardia of 100 beats per minute. Computed tomography showed that the cyst, which contained calcified structures, originated from her left ovary. After laparoscopy-assisted removal of the twisted ovarian cyst, her symptoms resolved completely. Histological examination confirmed a benign ovarian teratoma.
An unusual case of torsion of an ovarian teratoma presenting with abdominal pain and generalized pruritus, believed to be due to an antibody-mediated response, was resolved after surgical removal of the cyst.
Primary teratomas of retroperitoneum are not usual in the adult population. These tumors most commonly seen at the gonadal and sacrococcygeal regions. Herein we describe a case of an 18-year-old female who had a benign cystic teratoma at the retroperitoneum.
PRESENTATION OF CASE
The patient underwent an operation at another hospital following a misdiagnosis of hydatid cyst. The patient was referred to our hospital because of the detection of an unresectable tumor during her operation. A computerized tomography (CT)–angiography revealed a cystic mass, with a diameter of 14 cm which was invaded into the retrohepatic suprarenal inferior vena cava and also extended to the posterior aspect of the liver. Additionally the mass invaded the posterior wall of the inferior vena cava and the right renal vein. The tumor was completely resected with a vascular resection. The inferior vena cava was reconstructed with a 12 cm Dacron® graft and the renal vein was implanted. The patient's postoperative period was uneventful.
Germ cell tumors of retroperitoneum are usually seen in children, but there are also some reports of adult cases in the literature. Adult cases are especially seen in females. Imaging studies are paramount for diagnosis, preoperative strategy and safe surgical excision. CT scans and MRIs can identify various components of these tumors.
Even though primary retroperitoneal teratomas are quite rare in adults. Preoperative radiology imaging and strategy is critical for performing a safe surgery. The gold standard treatment strategy for this neoplasm is the surgical resection.

Retroperitoneal cysts are rare, usually asymptomatic, abdominal lesions. Epidermoid cysts developing in this space usually occur in middle-aged women and are incidentally discovered in the presacral region during ultrasound examination. Occasionally, cysts may arise from splenic tissue or adrenal glands and develop above the presacral area.
PRESENTATION OF CASE
We present the unusual location of a cyst in the retroperitoneal space in a 41-year-old woman admitted to hospital due to detection of a lesion in ultrasound imaging. A CT scan confirmed large intra-abdominal cyst. At operation, a large retroperitoneal thin-walled cyst with no evident arising point was discovered. Histologic analysis revealed epidermoid cyst.
Our patient presented with giant retroperitoneal cyst extending from the subhepatic region to the uterine and bladder. To our knowledge, this unusual location in adult has not been previously reported in the literature. In our case the lesion was adjacent to inferior vena cava and mesenteric vessel which required special attention during preparation and was technically demanding.
Surgery is the gold standard for the diagnosis and treatment of retroperitoneal epidermoid cysts. Successful treatment of benign retroperitoneal epidermoid cysts depends on appropriate diagnosis, careful operative technique, and adequate management of the underlying pathology.

Primary retroperitoneal teratomas involving adrenal glands are exceedingly uncommon accounting for only 4% of all primary teratomas. They are more common in childhood and rarely occur in adults. Only a very few case reports have been documented in literature so far. Herein, we report a mature (benign) cystic retroperitoneal teratoma in the region of left adrenal gland in a 22-year-old otherwise healthy male patient who presented with a 1-month history of left flank pain. In addition, a literature review on teratomas is included.
Retroperitoneal lymph node dissection has been advocated for the management of post-chemotherapy (PC-RPLND) residual masses of non-seminomatous germ cell tumors of the testis (NSGCT). There remains some debate as to the clinical benefit and associated morbidity. Our objective was to report our experience with PC-RPLND in NSGCT.
We have reviewed the clinical, pathologic and surgical parameters associated with PC-RPLND in a single institution. Between 1994 and 2008, three surgeons operated 73 patients with residual masses after cisplatin-based chemotherapy for a metastatic testicular cancer. Patients needed to have normal postchemotherapy serum tumor markers, no prior surgical attempts to resect retroperitoneal masses and resectable retroperitoneal tumor mass at surgery to be included in this analysis
Mean age was 30.4 years old. Fifty-three percent had mixed germ cell tumors. The mean size of retroperitoneal metastasis was 6.3 and 4.0 cm, before and post-chemotherapy, respectively. In 56% of patients, the surgeon was able to perform a nerve sparing procedure. The overall complication rate was 27.4% and no patient died due to surgical complications. The pathologic review showed presence of fibrosis/necrosis, teratoma and viable tumor (non-teratoma) in 27 (37.0%), 30 (41.1%) and 16 (21.9%) patients, respectively. The subgroups presenting fibrosis and large tumors were more likely to have a surgical complication and had less nerve sparing procedures.
PC-RPLND is a relatively safe procedure. The presence of fibrosis and large residual masses are associated with surgical complications and non-nerve-sparing procedure.
A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC). The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

A 48-year-old male who presented with an enlarged right scrotum was diagnosed with malignant transformation of testicular teratoma. Physical examination revealed a right scrotal mass of hard consistency with no inguinal lymphadenopathy. Since prepuberty, his right testis had been larger than the left one, with no pain or tenderness. Computed tomography and bone scan revealed retroperitoneal lymphadenopathy and multiple bone metastases. Right orchiectomy was performed immediately, and a pathological examination revealed a mature teratoma associated with adenocarcinoma, showing signet ring cell differentiation. Cisplatin-based combination chemotherapy was administered; however, the metastatic lesions progressed, and the patient succumbed to the disease after 15 months. Only a few cases of primary malignant transformation of teratoma in the testis have been reported, and this is the first case report of primary malignant transformation of teratoma in the testis with signet ring cell-type differentiation.

Congenital germ cell tumors are uncommon. The most common site of teratoma is in the sacrococcygeal region. Teratoma arising from the head and neck comprises less than 10% of reported cases and of these, nasopharyngeal lesions are rare. Teratomas are generally benign, and have a well recognized clinical and histopathological entity. We present a case of nasopharyngeal teratoma (NPT) associated with a wide cleft palate.
A 20 day old female neonate with a teratoma of the nasopharyngeal area, and wide cleft palate was referred to our center. The protruded mass which measured 6×4×3cm, was of soft consistency, blocked the airway, and prevented oral feeding. Preoperative evaluation and imaging was performed and mass was excised 2 days after admission. Pathology revealed a well-differentiated mature solid teratoma (hairy polyp). The patient had no complication in the post-operative period. Cleft palate was surgically repaired when 2 years old. She is now a six year old girl with normal development.
Congenital nasopharyngeal teratomas are usually benign. Surgery is the treatment of choice, and should be undertaken on an urgent basis, especially in a patient who presents with signs and symptoms of airway obstruction.

In the literature, 51 cases of primary retroperitoneal mucinous cystadenocarcinoma have been published. We report the fourth case occurring in a male patient. The 42-year-old patient presented with multiple retroperitoneal cystic masses causing abdominal discomfort without alteration of the global clinical state. The masses were totally removed by a two-stage surgery. No other treatment has been introduced. After a follow-up of 6 months, the patient is disease-free. This rare tumor most likely arises from the mucinous metaplasia of peritoneal inclusion cysts rather than from ectopic ovarian tissue or ovarian teratomas. The occurrence of such a tumor in a male patient supports this theory. Preoperative diagnosis is mostly difficult. Clinical behavior and treatment are still controversial.
Pancreatic acinar cell carcinoma is a rare malignant pancreatic neoplasm. To the best of our knowledge, there has been no report on spontaneous rupture of acinar cell carcinoma.
PRESENTATION OF CASE
A 39-year-old Azari male presented with a history of sudden onset, acute epigastric pain of 12-h duration. Eight hours later the patient's general condition rapidly deteriorated, blood pressure was decreased to 90/70 mm/Hg and heart rate was increased to 120 beat/min. Emergent abdominal computed tomography scan showed a well-defined hypo-dense, necrotic mass, measured 12 cm × 12 cm that was originating from the uncinate process of pancreas with marked free peritoneal fluid and extensive haziness of retroperitoneal and mesenteric fat compatible with marked bleeding. Emergent abdominal operation was performed and histopathology revealed acinar cell carcinoma of the pancreas.
Pancreatic acinar cell carcinoma (ACC) usually presents with abdominal pain, nausea and vomiting. To best of our knowledge, no report has been made of spontaneous rupture of ACC.
Pancreatic carcinoma may present as acute abdomen due to rupture of underlying neoplasm.

Primary retroperitoneal teratoma is a rare entity in adults. We present a case of 23-yearsold female who presented with complaint of abdominal pain in left upper quadrant. Computed tomography scan revealed a retroperitoneal retropancreatic teratoma near celiac axis with intra thoracic extension. Laparotomy with tumor resection was done. The case report is interesting for intra thoracic extension of retropancreatic teratoma.

The retroperitoneum is an uncommon location for teratoma in adults. The current study presents the case of a rare giant primary retroperitoneal teratoma in a 55-year-old female. The clinical manifestations, diagnosis and surgical treatment procedure of this case are retrospectively reviewed. The patient presented with a complaint of an abdominal palpable mass and fullness for 1 month. The patient suffered a massive hemorrhage during the first exploratory laparotomyand only a small section of the tumor was resected. Pathology revealed a mature retroperitoneal teratoma. Eleven months after the first surgery, the tumor was resected successfully at the second laparotomy. The surgical specimen was a large tumor mass measuring 22×18×10 cm in size and weighing 6 kg. At follow-up, the patient was in a stable condition. This case study highlights the importance of imaging for the development of a pre-operative strategy and performing a safe surgical excision in giant retroperitoneal teratoma cases.

Teratomas are the commonest germ cell tumours and are most frequently found in the testes and ovary. Extragonadal teratomas are rare and mainly occur in midline structures. Uterine teratomas are extremely rare with only a few previous case reports, usually involving mature teratomas of the uterine cervix.
We report an 82-year-old lady presenting with post-menopausal bleeding. Initial investigations revealed a benign teratoma of the uterus which was removed. Her symptoms persisted and a recurrent, now malignant, teratoma of the uterine corpus was resected at hysterectomy. Six months after surgery she relapsed with para-aortic lymphadenopathy and was treated with a taxane, etoposide and cisplatin-containing chemotherapy regimen followed by retroperitoneal lymph node dissection.
In this report we discuss the aetiology, diagnosis and management of uterine teratomas, and review previous case studies.
Giant cell arteritis is the most common form of large-vessel vasculitides. However, it is probable that extracranial involvement is underdiagnosed in patients with classical giant cell arteritis. In the recent literature most cases of giant cell arteritis have been described in conjunction with aortic aneurysms or dissections. Nonetheless the coexistence of giant cell arteritis and retroperitoneal fibrosis is extremely rare. Here, we describe a case of giant cell arteritis at a very early clinical stage, in a woman with coexistence of retroperitoneal fibrosis.
We report a case of giant cell arteritis at a very early clinical stage, in a 47-year-old Greek woman with coexistence of retroperitoneal fibrosis who was admitted to our hospital with a history of high-grade fever and mild right periumbilical abdominal pain for the past 30 days. In the context of fever of unknown origin, an abdomen computed tomography was ordered. A temporal artery biopsy was also performed because during hospitalization she complained of a headache. Examination of eosin and hematoxylin slides from biopsy specimens of her temporal artery, showed lesions consisting of predominantly lymphocytes, few plasma cells and occasional polymorphonuclear leucocytes. In addition no giant cells were detected in examining biopsies at multiple levels. This was consistent with giant cell arteritis according to the American college of Rheumatology criteria. An abdomen computed tomography revealed the presence of a retroperitoneal soft-tissue mass located anteriorly to the upper infrarenal aorta at the site of the scintigraphic uptake. The computed tomography and magnetic resonance imaging characteristics of the mass were consistent with retroperitoneal fibrosis, and its morphology suggestive of benignity. Our patient started oral prednisolone and was afebrile from day one.
In our experience this is the first case of retroperitoneal fibrosis due to giant cell arteritis occurring at the same time. Involvement of the aorta (aortitis) and its branches has been also observed in a subset of patients with giant cell arteritis. In addition, giant cell arteritis has been associated with a markedly increased risk of aortic aneurysm particularly thoracic aortic aneurysm.

Growing teratoma syndrome is a rare occurrence with an ovarian tumor. Anesthesia has been reported to be difficult in cases of growing teratoma syndrome of the cystic type due to the pressure exerted by the tumor. However, there have been no similar reports with the solid mass type. Here, we report our experience of anesthesia in a case of growing teratoma syndrome of the solid type.
The patient was a 30-year-old Japanese woman who had been diagnosed with an ovarian immature teratoma at age 12 and had undergone surgery and chemotherapy. However, she dropped out of treatment. She presented to our hospital with a 40cm giant solid mass and severe respiratory failure, and was scheduled for an operation. We determined that we could not obtain a sufficient tidal volume without spontaneous respiration. Therefore, we chose to perform awake intubation and not to use a muscle relaxant before the operation. At the start of the operation, when muscle relaxant was first administered, we could not obtain a sufficient tidal volume. An abdominal midline incision was performed immediately and her tidal volume recovered. Her resected tumor weighed 10.5kg. After removal of her tumor, her tidal volume was maintained at a level consistent with that under spontaneous respiration to avoid occurrence of re-expansion pulmonary edema.
We performed successful anesthetic management of a case of growing teratoma syndrome with a giant abdominal tumor. Respiratory management was achieved by avoiding use of a muscle relaxant before the operation to maintain spontaneous respiration and by maintaining a relatively low tidal volume, similar to that during spontaneous respiration preoperatively, after removal of the tumor to prevent re-expansion pulmonary edema.

Teratomas are neoplasms that arise from pluripotent cells and can differentiate along one or more embryonic germ lines. Renal teratoma is an exceedingly rare condition. Teratomas commonly arise in the gonads, sacrococcygeal region, pineal gland, and retroperitoneum. They present mainly as an abdominal mass with few other symptoms. Majority of the tumors are benign, situated on the left side and para renal, occasional lesions are bilateral. If diagnosed early, they are amenable to curative excision.
Renal teratomas are rare and most have been dismissed as cases of teratoid nephroblastomas or retroperitoneal teratomas secondarily invading the kidney. The differentiation between these two neoplasms in the kidney is often problematic.
We present a case of intrarenal immature teratoma in a six-month-old baby girl.

Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Primary retroperitoneal teratomas are rare and present challenging management options. We report a case of a unilateral primary retroperitoneal mature cystic teratoma mimicking an adrenal mass in a 54-year-old male patient. Complete resection of the adrenal mass was performed by the flank approach by using the 11th rib resection. Because of the risk of malignancy, follow-up radiographic studies were performed to ensure the oncologic efficacy of resection. The patient has been free of recurrence for longer than 12 months.

We report a rare case of adenocarcinoma in retroperitoneal teratoma in a 38 year old female patient who attended surgical OPD with complaints of dragging pain and heaviness in left lumbar region. Straight x-ray abdomen showed few irregular calcifications in left lumbar region. USG and CT showed it to be adrenal tumor and retroperitoneal teratoma respectively. Excised specimen confirmed it as mucin secreting adenocarcinoma in a case of retroperitoneal teratoma.

The most common type of ovarian germ cell tumor is the teratoma. Thyroid tissue, both benign and malignant, may be a component of an ovarian teratoma. Here we review this topic and illustrate major features by presenting multimodal management of a patient with BRAF-positive disseminated follicular thyroid cancer arising in an ovarian teratoma.
Malignant thyroid tissue is often difficult to distinguish from benign thyroid tissue arising in ovarian teratomas. Preoperatively, an elevated thyroglobulin (Tg) level, laboratory or clinical evidence of hyperthyroidism, or ultrasonography appearance of “struma pearl” should prompt referral to oncologist for surgical management of a possibly malignant ovarian teratoma. Postoperatively, tumor tissue should be referred to pathologists experienced with differentiating benign from malignant struma ovarii. Once diagnosed, treatment of this rare condition should be handled by a team of specialists with combined treatment modalities. We cared for woman with disseminated thyroid cancer arising in an ovarian teratoma whose history illustrates the complexity of managing ovarian teratomas with malignant thyroid tissue. At age 33 she had an intraoperative rupture of an ovarian cyst, thought to be struma ovarii. During her next pregnancy, pelvic masses were noted; biopsies revealed well-differentiated papillary thyroid carcinoma, follicular variant. She was euthyroid, but had elevated serum Tg levels. Surgical staging demonstrated widely metastatic intraabdominal dissemination. A thyroidectomy revealed no malignancy. A post-131I treatment scan revealed diffuse uptake throughout the abdomen. She then developed abdominal pain and, on computed tomography, was found to have multiple intraabdominal foci of disease. Serum Tg was 264 ng/mL while on L-thyroxine for hypothyroidism and to obtain thyrotropin suppression. A 18 fluorodeoxyglucose positron emission tomography scan showed no pathological uptake. The tumor was found to be BRAF mutation positive (K601E). She underwent extensive secondary debulking and a second course of 131I with lithium pretreatment. Posttreatment scan revealed diffuse abdominal uptake. Six months posttherapy, the patient is asymptomatic with a serum Tg of 18.1 ng/mL.
Aggressive multimodal management appears to be the most promising approach for malignant thyroid tissue arising in ovarian teratomas.
Retroperitoneal necrotizing fasciitis is a rare, fulminant, and potentially lethal complication of intra-abdominal suppuration. A retroperitoneal origin is very rare and very few cases have been reported in the literature. To the best of our knowledge, this case is only the fourth case reported of successful management following retroperitoneal necrotizing fasciitis.
A 33-year-old Tamang man presented to our facility with a history of five days of fever and vomiting and eight days of severe left loin pain. On examination, he had features of peritonism. A laparotomy was performed, revealing extensive necrotizing fasciitis of the retroperitoneum extending to the anterior abdominal wall. Our patient survived following extensive debridement of the necrotic tissues and supportive care.
Retroperitoneal necrotizing fasciitis can rarely present with features of peritonism, and hence should be included as a possible differential diagnosis for anyone presenting with peritonism. Although a fatal condition, early intervention and aggressive management can save the life of a patient.
Teratomas are embryonal neoplasms that arise when totipotential germ cells escape the developmental control of primary organizers and give rise to tumors containing tissue derived from all three blastodermic layers. Teratomas have been reported to occur in various sites and organs. Teratoma of the cervical neck are relatively rare in adulthood. It usually extends from the neck to the thoracic cavity causing local mass effect. In most of the cases intrauterine diagnosis is possible by ultrasound. Because of dyspnea due to mass effect, this condition is treated promptly after birth. However cases of teratoma in adulthood with supraclavicular localization have been reported rarely in the literature. The presented case is of a 25-year-old female with a cervical mass. Histological examination revealed a benign mature teratoma. The patient has been disease free for more than nine years after surgical removal of a neck teratoma.

Recent studies have demonstrated that pathological analysis of retroperitoneal residual masses of patients with testicular germ cell tumors revealed findings of necrotic debris or fibrosis in up to 50% of patients. We aimed at pursuing a clinical and pathological review of patients undergoing post chemotherapy retroperitoneal lymph node dissection (PC-RPLND) in order to identify variables that may help predict necrosis in the retroperitoneum.
We performed a retrospective analysis of all patients who underwent PC-RPLND at the University Hospital of the University of São Paulo and Cancer Institute of Sao Paulo between January 2005 and September 2011. Clinical and pathological data were obtained and consisted basically of: measures of retroperitoneal masses, histology of the orchiectomy specimen, serum tumor marker and retroperitoneal nodal size before and after chemotherapy.
We gathered a total of 32 patients with a mean age of 29.7; pathological analysis in our series demonstrated that 15 (47%) had necrosis in residual retroperitoneal masses, 15 had teratoma (47%) and 2 (6.4%) had viable germ cell tumors (GCT). The mean size of the retroperitoneal mass was 4.94 cm in our sample, without a difference between the groups (P = 0.176). From all studied variables, relative changes in retroperitoneal lymph node size (P = 0.04), the absence of teratoma in the orchiectomy specimen (P = 0.03) and the presence of choriocarcinoma in the testicular analysis after orchiectomy (P = 0.03) were statistically significant predictors of the presence of necrosis. A reduction level of 35% was therefore suggested to be the best cutoff for predicting the absence of tumor in the retroperitoneum with a sensitivity of 73.3% and specificity of 82.4%.
Even though retroperitoneal lymph node dissection remains the gold standard for patients with residual masses, those without teratoma in the primary tumor and a shrinkage of 35% or more in retroperitoneal mass have a considerably smaller chance of having viable GCT or teratoma in the retroperitoneum and a surveillance program could be considered.

Spontaneous rupture of the spleen is an uncommon dramatic abdominal emergency that requires immediate diagnosis and prompt surgical treatment to ensure the patients survival. Infections have been cited in most cases involving splenic rupture but are rare in hematological malignancies despite frequent involvement of the spleen.
Methods and Materials
We present a case of a splenic rupture caused by infiltration of B-cell lymphoma. A 43 year old gentleman presented with a 1 day h/o left upper quadrant pain; nausea and vomiting for 2 days with associated dizziness and anorexia. The CT showed abnormal spleen 20 × 11 cm with free fluid in the abdomen and enlarged retroperitoneal LNs. The patient underwent a splenectomy after initial resuscitation and the operative finding was that of a massively enlarged spleen with areas of tumor extruding through the splenic capsule.
Result and conclusion
Although the spleen is often involved in hematological malignancies, splenic rupture is an infrequent occurrence. In a recent literature review 136 cases were of splenic rupture secondary to hematological malignancy were identified. Acute leukemia and non Hodgkin lymphoma were the frequent causes followed by chronic myelogeneous leukemia. Male sex, adulthood, severe splenomegaly and cytoreductive chemotherapy were factors more often associated with splenic rupture. Emergency splenectomy remains the cornerstone treatment for splenic rupture.
We present a case report of a "spontaneous splenic rupture" and discuss the presentation, etiology and treatment options along with discussion of relevant literature
Necrotizing fasciitis (NF) is an uncommon soft tissue infection, usually caused by toxin-producing virulent bacteria. It is characterized by widespread fascial necrosis primarily caused by Streptococcus hemolyticus. Shortly after the onset of the disease, patients become colonized with their own aerobic and anaerobic microflora from the gastrointestinal and/or urogenital tracts. Early diagnosis with aggressive multidisciplinary treatment is mandatory. We describe three clinical cases with NF. The first is a 69 years old man with diabetes mellitus type II, who presented with NF on the posterior chest wall, shoulder and arm. He was admitted to the intensive care unit (ICU) with a clinical picture of severe sepsis. Outpatient treatment and early surgical debridement of the affected zones (inside 3 hours after admittance) and critical care therapy were performed. The second case is of a 63 years old paraplegic man with diabetes mellitus type I. Pressure sores and perineal abscesses progressed to Fournier's gangrene of the perineum and scrotum. He had NF of the anterior abdominal wall and the right thigh. Outpatient treatment and early surgical debridement of the affected zones (inside 6 hour after admittance) and critical care therapy were performed. The third patient was a 56 year old man who had NF of the anterior abdominal wall, flank and retroperitoneal space. He had an operation of the direct inguinal hernia, which was complicated with a bowel perforation and secondary peritonitis. After establishing the diagnosis of NF of the abdominal wall and retroperitoneal space (RS), he was transferred to the ICU. There he first received intensive care therapy, after which emergency surgical debridement of the abdominal wall, left colectomy, and extensive debridement of the RS were done (72 hours after operation of inquinal hernia). On average, 4 serial debridements were performed in each patient. The median of serial debridement in all three cases was four times. Other intensive care therapy with a combination of antibiotics and adjuvant hyperbaric oxygen therapy (HBOT) was applied during the treatment. After stabilization of soft tissue wounds and the formation of fresh granulation tissue, soft tissue defect were reconstructed using simple to complex reconstructive methods.
