1.  Late onset of subfoveal choroidal neovascularisation following cerebral radiotherapy 
BMJ Case Reports  2010;2010:bcr0520091825.
A report of choroidal neovascularisation (CNV) associated with radiation retinopathy. A 43-year-old Caucasian man presented with a 4-week history of sudden loss of central vision in the left eye, 8.5 years following radical radiotherapy for left tempero-parietal anaplastic astrocytoma. His visual acuity was 6/6 in the right eye and 6/60 in the left eye. Ophthalmoscopy of the left eye showed central macular pigmented area surrounded by subretinal fluid, haemorrhage and exudates. Fundus fluorescein angiography revealed left subfoveal CNV with surrounding macular oedema and peripheral retinal ischaemia. Radiation retinopathy associated CNV is a late ocular complication of cerebral radiotherapy. It should be investigated as a possible aetiology of severe visual loss in long-term survivors of cerebral tumours who have previously received radiotherapy.

2.  Osteolytic bone destruction resulting from relapse of a testicular tumour 23 years after inguinal orchiectomy and adjuvant chemotherapy: a case report 
Introduction
Late relapse of a testicular germ cell tumour is an uncommon occurrence. We report a case of osteolytic bone metastasis appearing 23 years after the initial treatment of a metastatic testicular mixed tumour (choriocarcinoma and embryonal carcinoma). This is one of the longest periods of recurrence reported for testicular germ cell tumours.
Case presentation
A 52-year-old Caucasian man who underwent a right inguinal orchiectomy due to testicular tumour in 1984 presented to our outpatient clinic in a generally bad condition of health and with severe pain of his right hip joint and os ischii caused by osteolytic metastasis.
Conclusions
This case emphasizes the need for a life-long follow-up of patients with primary metastatic testicular cancer.

3.  Orbital Infiltration as the First Site of Relapse of Primary Testicular T-cell Lymphoma 
A 43-year-old male presented with a painless left testicular mass. The pathologic diagnosis of the radical orchiectomy specimen was peripheral T-cell lymphoma, unspecified (PTCL-u). According to the Ann Arbor staging system, his initial stage was III because of the right nasopharyngeal involvement. After first-line chemotherapy with four courses of the CHOP regimen and this was followed by involved-field radiotherapy, he achieved complete remission. Two months later, disease recurred to the left ciliary body of the left eye without evidence of involvement at other sites. Although the patient received intensive chemotherapy with autologous hematopoietic stem cell transplantation, he ultimately died of leptomeningeal seeding. Because both the central nervous system (CNS) and the orbit are sanctuary sites for chemotherapy, orbital infiltration of lymphoma should prompt physicians to evaluate involvement of the CNS and to consider performing prophylactic intrathecal chemotherapy as a treatment option.

4.  Chemo-resistant choriocarcinoma metastatic to colon cured by low-anterior resection 
Journal of Gynecologic Oncology  2011;22(3):203-206.
The role of surgery in the treatment of patients with metastatic choriocarcinoma has diminished. We present a case of chemo-resistant metastatic choriocarcinoma salvaged by surgery. A 48-year-old patient presented with uterine perforation and severe intractable hemorrhage, and histological examination revealed a choriocarcinoma. After 6 years of disease-free state, recurrence occurred in the rectosigmoid colon. Seven cycles of EMACO chemotherapy was administered, and the human chorionic gonadotropin level was normalized. Three months after the chemotherapy, the rectosigmoid colon metastasis progressed. Low anterior resection with lymphadenectomy up to the level of the inferior mesenteric artery was conducted. After the operation, the human chorionic gonadotropin level decreased to within the normal range. There has been no evidence of disease for 13 months since the operation. Local resection of metastases seems to play a significant role in curing the disease in a small subset of patients.

5.  Germ Cell Tumors of the Testes 
Western Journal of Medicine  1977;126(5):362-377.
Most malignant testicular neoplasms are of germ cell origin. They are divided into five basic types: seminomas, embryonal carcinomas, teratocarcinomas, adult teratomas and choriocarcinomas. Clinically they may present as an enlarging testicular mass, or with symptoms resulting from metastases or hormonal secretions. The treatment of choice for patients with seminomas is orchiectomy, followed by radiation therapy. This combination results in an 80 to 100 percent five-year survival rate in patients with nonmetastatic or locally metastatic disease. The treatment of nonseminomatous germ cell tumors is more controversial. An aggressive approach, however, with retroperitoneal lymph node dissection and adjuvant chemotherapy has resulted in an overall 78 percent survival rate. Several placental and fetal proteins are secreted by these tumors. Two of these, human chorionic gonadotropin and alpha-fetoprotein, have been shown to be useful for the diagnosis of these neoplasms, for following the disease activity during therapy and for detection of recurrences.

6.  Mixed Testicular Germ Cell Tumor Presenting as Metastatic Pure Choriocarcinoma Involving Multiple Lung Metastases That Was Effectively Treated with High-dose Chemotherapy 
Choriocarcinoma in the testis is very rare, and it represents less than 1% (0.3%) of all the testicular germ cell tumors. It is a particularly aggressive variant of non-seminoma tumor, which is characterized by a high serum β-HCG level and multiple lung metastases. The optimal management for this disease remains undefined. We report here on a case of choriocarcinoma with multiple lung metastases, and the patient has achieved continuous remission for 2 years after combination chemotherapy of BEP (bleomycin, etoposide and cisplatin) and sequential high-dose chemotherapy with autologous peripheral stem cell rescue.

7.  Retroperitoneal teratoma with somatic malignant transformation: A papillary renal cell carcinoma in a testicular germ cell tumour metastasis following platinum-based chemotherapy 
BMC Urology  2013;13:9.
Background
Malignant transformation describes the phenomenon in which a somatic component of a germ cell teratoma undergoes malignant differentiation. A variety of different types of sarcoma and carcinoma, all non-germ cell, have been described as a result of malignant transformation.
Case presentation
A 33-year-old man presented with a left testicular mass and elevated tumour markers. Staging investigations revealed retroperitoneal lymphadenopathy with obstruction of the left ureter and distant metastases. Histopathology from the left radical orchiectomy showed a mixed germ cell tumour (Stage III, poor prognosis). The ureter was stented and four cycles of cisplatin, etoposide and bleomycin chemotherapy administered. After initial remission, the patient recurred four years later with a large retroperitoneal mass involving the renal vessels and the left ureter. Left retroperitoneal lymph node dissection with en-bloc resection of the left kidney was performed.
Histopathology revealed a germ cell tumour metastasis consisting mainly of mature teratoma. Additionally, within the teratoma a papillary renal cell carcinoma was found. The diagnosis was supported by immunohistochemistry showing positivity for AMACR, CD10 and focal expression of RCC and CK7. There was no radiological or histo-pathological evidence of a primary renal cell cancer.
Conclusions
To the best of our knowledge, malignant transformation into a papillary renal cell carcinoma has not been reported in a testicular germ cell tumour metastasis following platinum-based chemotherapy. This histological diagnosis might have implications for potential future therapies. In the case of disease recurrence, renal cell cancer as origin of the recurrent tumour has to be excluded because renal cell carcinoma metastases would not respond well to the classical germ cell tumour chemotherapy regimens.

8.  Small Choroidal Melanoma with Monosomy 3 
Purpose:
To report a patient with small juxtapapillary choroidal melanoma with chromosome 3 monosomy treated with I125 plaque and transpupillary thermotherapy (TTT). A 64-year-old Caucasian male presented with painless blurred vision of the left eye. Ocular examination disclosed a small juxtapapillary choroidal melanocytic tumor with overlying subretinal fluid and orange pigment. Ultrasound showed an elevated choroidal mass of 2 mm thickness with low reflectivity on A-scan and hollowness on B scan, consistent with a small choroidal melanoma. The patient was treated with plaque I125 radiotherapy combined with one session of TTT. Genetic testing of the tumor cells obtained by fine needle aspiration biopsy showed chromosome 3 monosomy. At 1 year after treatment, the tumor was regressed with resolution of subretinal fluid and 20/40 visual acuity. A small choroidal melanoma can manifest monosomy of chromosome 3, a known predictive factor for the development of systemic metastasis.

9.  Mixed germ cell tumor metastatic to the skin: Case report and literature review 
Background
Testicular cancer is the most common cancer for males aged 15~35 years old. The initial presentation is typically an asymptomatic enlarged testicle. The retroperitoneum is the most common metastatic area. Other metastatic sites include the lung, liver, brain, adrenal glands, gastrointestinal tract and spleen. Skin metastasis is a rare event and frequently associated with poor prognosis.
Case presentation
A 19-year old male was diagnosed testicular mixed germ cell tumor with initial presentation of cutaneous metastasis at scalp and upper abdomen. After radical orchiectomy and four courses of cisplatin-based chemotherapy, the scalp and upper abdominal lesions regressed completely. The size of lung metastases remained unchanged.
Conclusions
For advanced stage testicular cancer, cisplatin-based chemotherapy is still effective to achieve partial response.

10.  Malignant transformation of an intracranial germinoma into a choriocarcinoma 
BMJ Case Reports  2009;2009:bcr12.2008.1351.
The recurrence or metastasis of intracranial pure germinomas as germ cell tumours of different histological types has rarely been reported. The present report concerns the first case in the literature of intracranial recurrence of a germinoma transformed into a choriocarcinoma. A 17-year-old man presented with a 1 month history of headache. MRI revealed a homogeneously enhanced mass within the pineal and suprasellar regions. The tumour was resected, and histological examination identified it as a pure germinoma. After resection, the patient underwent chemotherapy and radiotherapy and the mass disappeared. At 5 years and 5 months later, the patient presented with nausea and headache, and recurrence of the tumour was revealed in the left lateral ventricle. The tumour was resected and histological diagnosis identified it as a choriocarcinoma. The patient was treated with chemotherapy and radiotherapy, but died due to dissemination 1 month later. An autopsy was not performed.

11.  Systemic chemotherapy and tamoxifen induced regression of choroidal metastasis from a breast carcinoma in a male 
Indian Journal of Ophthalmology  2007;55(6):475-477.
We report a case of a 55-year-old male patient with breast carcinoma, who developed choroidal metastasis. The patient had undergone mastectomy for carcinoma of right breast, five years ago. The patient was advised close follow-up for the left eye, as he was already on tamoxifen therapy (started a month ago) for spinal metastasis. On last follow-up, a year later, the choroidal lesion had completely scarred, with no recurrences. Systemic hormonal therapy like tamoxifen given for the breast primary and other systemic metastases may cause regression of the choroidal metastasis, thereby avoiding ocular radiotherapy. Medline search revealed only one published case of regression of choroidal metastasis from a male breast primary, on tamoxifen therapy.

12.  Non-small cell lung cancer presenting with choroidal metastasis as first sign and showing good response to chemotherapy alone: a case report 
Introduction
Metastatic tumors are the most common intra-ocular malignancies and choroid is by far the most common site for intra-ocular malignancies. Multiple foci are usually involved, and bilateral involvement is frequently seen. The primary sites for choroidal metastasis in decreasing order and by gender are: breast, lung, unknown primary, gastrointestinal and pancreas, skin melanoma and other rare sources in females, and lung, unknown primary, gastrointestinal and pancreas, prostate, kidney, skin melanoma and other rare sources in males. Available treatment options are external beam radiotherapy and plaque radiotherapy, while new methods like surgical resection, transpupillary thermotherapy and intravitreal chemotherapy offer promises for the future. The use of chemotherapy alone for choroidal metastases is not widely reported.
Case presentation
We report the case of a 50-year-old Indian man who had a unilateral solitary lesion in his right eye. He was found to have an adenocarcinoma of the lung with choroidal metastasis as the first presenting sign. There were no findings of metastasis involving his contralateral eye. He was administered chemotherapy based on gemcitabine and carboplatin. He had significant progressive subjective and objective improvement since his first chemotherapy. His current best corrected visual acuity is 20/60 after three cycles of chemotherapy.
Conclusions
Chemotherapy alone can be used as an effective mode of treatment in patients who have primary tumors that respond to chemotherapy.

13.  Polyarteritis Nodosa with Bilateral Asynchronous Testicular Necrosis: A Case Report 
Case Reports in Urology  2011;2011:465353.
Polyarteritis nodosa (PAN) is a systemic vasculitis which may result in thrombosis or aneurysm formation in any organ of the body. We report a case polyarteritis nodosa (PAN) resulting in bilateral asynchronous testicular necrosis. A 55-year-old male developed acute onset of left testicular pain resulting in a left orchiectomy and right orchidopexy for an ischemic left testicle without evidence of torsion. Three weeks later, the patient developed acute right-sided scrotal pain, and surgical exploration revealed a right necrotic testicle resulting in a right orchiectomy. Pathologic evaluations demonstrated benign testes with acute interstitial hemorrhage and focal atrophy. The patient also experienced abdominal skin necrosis, penile pain and swelling, and temporary loss of vision. This is a unique case of PAN and the only case of asynchronous testicular necrosis in the medical literature.

14.  Inguinal lymph node metastases from a testicular seminoma: a case report and a review of the literature 
Introduction
We report the case of a true hermaphrodite with testicular seminoma with resulting metastases to the inguinal lymph nodes eight months after radical orchidectomy. This is an unusual presentation of testicular cancer and, to the best of our knowledge, the first report of this kind in the literature.
Case presentation
A 45-year-old Caucasian true hermaphrodite, raised as a male, developed a testicular seminoma. He had undergone a left orchidopexy at the age of 10 for undescended testes. Metastases from testicular tumors to inguinal lymph nodes are a rare occurrence. It has been suggested that previous inguinal or scrotal surgery may alter the pattern of nodal metastasis of testicular cancer. We review the literature to evaluate the incidence of inguinal lymph node involvement in early stage testicular cancer and discuss possible routes of metastases to this unusual site. We also discuss the management of the inguinal lymph nodes in patients with testicular tumors and a previous history of inguinal or scrotal surgery, as this remains controversial.
Conclusion
Inguinal lymph node metastases from testicular cancer are rare. A history of inguinal or scrotal surgery may predispose involvement of the inguinal nodes. During radical inguinal orchidectomy, the surgeon should be careful to minimize the handling of the testis and ensure high ligation of the spermatic cord up to the internal inguinal ring to reduce the risk of inguinal lymph node metastasis.

15.  Primary intratesticular leiomyosarcoma 
This report presents a case of primary intratesticular leiomyosarcoma. A 73-year-old male presented with a 6-year history of left scrotal swelling. A radiological examination revealed a left testicular tumour with multiple metastases in the lung, para-aortic lymph node and other organs. A radical orchiectomy was carried out and the pathology revealed an intratesticular leiomyosarcoma. The patient received additional chemotherapy. Cases of primary intratesticular leiomyosarcoma are rare. This is, to the best of our knowledge, only the tenth case of leiomyisaocoma in an adult reported in the literature, and the first case involving multiple metastases.

16.  Successful synchronous chemotherapy and radiotherapy followed by consecutive chemotherapy without surgery for primary intracranial choriocarcinoma: A case report 
Oncology Letters  2012;4(6):1389-1391.
We experienced a rare case of primary intracranial choriocarcinoma treated successfully with synchronous chemotherapy and radiotherapy followed by three consecutive courses of chemotherapy without surgery. A 19-year-old male patient presented with a two-week history of diplopia, headache, nausea and vomiting. Neurological examination revealed visual disturbance, bilateral hearing loss, bilateral sixth nerve palsy, left skew deviation, downgaze limitation and clockwise torsional nystagmus on the left upgaze. During image evaluation, the patient suddenly presented with a confused mental status, bradycardia and decreased respiration. An emergency third ventriculostomy was conducted, followed by synchronous ifosfamide, cisplatin and etoposide chemotherapy (ICE; I, 900 mg/m2; C, 20 mg/m2; and E, 60 mg/m2) on days 1–5, and external radiotherapy (whole brain, 30 Gy/15 Fxs; local boost, 30 Gy/15 Fxs) followed again by three consecutive courses of chemotherapy. This therapy resulted in tumor regression by 63% and full improvement in the patient’s neurological condition. However, it was difficult to remove the remaining tumor using a surgical approach due to the risk of postoperative hemorrhage and limited access. We planned to observe the remaining mass without surgery. This patient is now alive and the mass size has not changed for 18 months since treatment. This is the first report of the effectiveness of synchronous chemotherapy and radiotherapy followed by consecutive chemotherapy without surgery in a patient with primary intracranial choriocarcinoma.

17.  Cutaneous Metastasis of Choriocarcinoma : A Case Report 
Journal of Korean Medical Science  2005;20(4):683-686.
Choriocarcinoma is one of the malignant tumors of trophoblastic cells characterized by the secretion of human chorionic gonadotrophin (hCG) (1-3). Cutaneous metastasis is a rare presentation of choriocarcinoma but a poor prognostic sign because it is associated only with widespread disease (3-5). A 52-yr-old female complaining of dyspnea for 2 months, presented with fingertip sized erythematous nodules on the left side of the neck and the right side of the upper back of 1 month duraton. She has suffered from Behçet's disease since 1999. Microscopic examination of a nodule of upper back demonstrated biphasic pattern of cytotrophoblasts and hCG-positive syncytiotrophoblasts, and the typical histologic features of choriocarcinoma. She was referred to the gynecological oncology department. After 17 cycles of combination chemotherapy, the serum hCG level has fallen from 700,000 to under 2.0 mIU/mL and the skin lesions have almost disappeared. However, after 3 months, total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed due to elevated serum hCG level (4,447.7 mIU/mL), and she is scheduled to receive post-operative adjuvant chemotherapy.

18.  Bilateral Choroidal Metastases as Presentation of Dissemination of Cutaneous Malignant Melanoma 
Case Report. A 47-year-old man presented with blurred vision in the right eye. Ophthalmoscopic examination showed several placoid, pigmented lesions in the posterior pole and midperiphery of the retina of both eyes. Results. Patient referred a cutaneous malignant melanoma on the back skin removed 6 years ago. A systemic workup revealed multiple metastases in liver and spleen. After an exhaustive study we concluded that it was a dissemination of a cutaneous malignant melanoma with bilateral choroidal metastases, liver and spleen metastases. The patient obtained clinical ocular improvement after palliative chemotherapy, although he died in the following months. Pathological examination of the lesions confirmed the diagnosis of choroidal metastases from a malignant cutaneous melanoma. Conclusions. Monitoring patients who have had cutaneous malignant melanoma is very important, since melanoma metastases may occur even many years after the diagnosis of the primary tumor. Choroidal metastases from cutaneous melanoma are uncommon but we should be aware because their appearance worsens prognosis.

19.  Prolonged survival in a patient with choroidal metastases from urothelial bladder cancer 
Choroidal metastases secondary to urothelial carcinoma are extremely rare and are usually associated with an extremely poor prognosis. We present a case of an 88-year-old man with newly diagnosed urothelial carcinoma of the bladder who presented with acute loss of vision before commencing definitive concurrent chemoradiotherapy to the bladder. Ophthalmological examination demonstrated bilateral choroidal metastases. He received palliative radiotherapy to the orbits and completed his planned radiotherapy to the bladder. He remained disease-free at last follow-up 4 years after the completion of treatment. We review the literature particularly with regard to diagnosis and management of choroidal metastases. Choroidal metastases should be considered in a patient with a history of urothelial cancer presenting with new onset of eye symptoms.

20.  Cervical mature teratoma 17 years after initial treatment of testicular teratocarcinoma: report of a late relapse 
Background
Late relapses of testicular germ cell tumor are uncommon. We report a case of cervical mature teratoma appeared 17 years after treatment of testicular teratocarcinoma.
Case presentation
A 20- year- old patient underwent left sided orchiectomy followed by systemic therapy and retroperitoneal residual mass resection in 1989. He remained in complete remission for 200 months. In 2005 a huge left supraclavicular neck mass with extension to anterior mediastinum appeared. Radical surgical resection of the mass was performed and pathologic examination revealed mature teratoma.
Conclusion
This is one of the longest long-term reported intervals of a mature teratoma after treatment of a testicular nonseminoma germ cell tumor. This case emphasizes the necessity for follow up of testicular cancer throughout the patient's life.

21.  Spontaneous acute subdural hematoma as an initial presentation of choriocarcinoma: A case report 
Introduction
Diverse sequelae of central nervous system metastasis of choriocarcinoma have been reported, including infarction, intra or extra axial hemorrhages, aneurysm formation and carotid-cavernous fistula. Here we report a case of subdural hematoma as the first presentation of choriocarcinoma.
Case presentation
The patient is a 34-year-old woman whose initial presentation of widely metastatic choriocarcinoma was an acute subdural hematoma, requiring decompressive craniectomy. Histopathologic examination of the tissue showed no evidence of choriocarcinoma, but the patient was found to have diffuse metastatic disease and cerebrospinal fluid indices highly suggestive of intracranial metastasis.
Conclusion
Choriocarcinoma frequently metastasizes intracranially. We review the diverse possible manifestations of this process. In addition, the cerebrospinal fluid:serum beta-human chorionic gonadotropin ratio is an important factor in diagnosing these cases. Finally, the role of the neurosurgeon is discussed.

BMJ Case Reports  2011;2011:bcr0920103320.
A 32-year-old lady presented postnatally with headaches, blurred vision and left leg numbness, which was initially diagnosed as migraine with sciatica. Subsequently, she developed seizures and was admitted to ITU. Investigations revealed abnormal grey matter perfusion in the right occipital region of the brain, multiple lung nodules, lesions in the liver and a pancreatic mass. A β-human chorionic gonadotrophin level was over 132 000 IU/l, and metastatic choriocarcinoma was diagnosed. She responded well to combination chemotherapy and made a full recovery.

23.  Bilateral Diffuse Uveal Melanocytic Proliferation Presenting as Small Choroidal Melanoma 
Purpose. To describe a patient with Bilateral Diffuse Uveal Proliferation who presented initially with a clinical picture consistent with choroidal melanoma. Methods. Presentation of a clinical case with fundus photos, fluorescein angiography, and optical coherence tomography. Results. A 70-year-old Caucasian male with history of esophageal cancer presented with an asymptomatic pigmented choroidal lesion in his left eye initially diagnosed as choroidal nevus. This lesion enlarged over the course of a year and developed orange pigment and increased thickness. A metastatic workup was negative, and a radioactive iodine plaque was placed on the left eye. Over the next six months, the visual acuity in his left eye decreased. His clinical picture was consistent with unilateral Diffuse Uveal Proliferation. A recurrence of his esophageal carcinoma with metastasis was discovered and palliative chemotherapy was initiated. Although his visual acuity improved in the left eye, similar pigmentary changes developed in the right fundus. His visual acuity in both eyes gradually decreased to 20/200 until his death a year later. Conclusion. BDUMP should always be considered in the differential diagnosis of patients with pigmented fundus lesions and a history of nonocular tumors.

24.  Gastric choriocarcinoma admixed with an α-fetoprotein-producing adenocarcinoma and separated adenocarcinoma 
We report a case of gastric choriocarcinoma admixed with an α-fetoprotein (AFP)-producing adenocarcinoma. A 70-year-old man was hospitalized for gastric cancer that was detected during screening by esophagogastroduodenoscopy (EGD). Initial laboratory data showed the increased serum level of AFP and EGD revealed a 5-cm ulcerofungating mass in the greater curvature of the gastric antrum. The patient underwent radical subtotal gastrectomy with D2 lymph node dissection and Billroth II gastrojejunostomy. Histopathological evaluation confirmed double primary gastric cancer: gastric choriocarcinoma admixed with an AFP-producing adenocarcinoma and separated adenocarcinoma. At 2 wk postoperatively, his human chorionic gonadotropin and AFP levels had reduced and six cycles of adjuvant chemotherapy were initiated. No recurrence or distant metastasis was observed at 4 years postoperatively.

25.  Concurrent development of testicular seminoma and choriocarcinoma of the superior mediastinum, presented as cervical mass: a case report and implications about pathogenesis of germ-cell tumours 
Background
Synchronous presentation of more than one germ cell tumours of different histology in the same patient is considered to be very rare. In these cases of multiple germ cell tumours, strong theoretical and clinical data suggest an underlying common pathogenetic mechanism concerning genetic instability or abnormalities during the pluripotent embryonic differentiation and maturation of the germ cell.
Case presentation
A 25 year-old young man presented with an enlarging, slightly painful left cervical mass. Despite the initial disorientation of the diagnosis to a possible thyroid disorder, the patient underwent complete surgical resection of the mass revealing mediastinal choriocarcinoma. Subsequent ultrasound of the scrotum indicated the presence of a small lobular node in the upper pole of the left testicle and the patient underwent radical left inguinal orchiectomy disclosing a typical seminoma. Based on these results, the patient received 4 cycles of Bleomycin, Etoposide and Platinum chemotherapy experiencing only mild toxicity and resulting in complete ongoing clinical and biochemical remission.
Conclusion
The pathogenesis of concurrent germ cell tumours in the same patient remains an area of controversy. Although the genetic instability of the pluripotent germ cell offers an adequate explanation, the possibility of metastasis from the primary, less differentiated tumour to a distant location as a more mature subtype cannot be excluded. Possible development of a metastatic site of different histology and thus biological behaviour (e.g choriocarcinoma) should be anticipated. Furthermore, urologists, pathologists and medical oncologists should be meticulous in the original pathological diagnosis in these patients, since there is a significant frequency of germ cell tumours with mixed or overlapping histological elements with diverse potential of evolution and differentiation.
