1.  Giant Malignant Cystic Pheochromocytoma: A Case Report 
The Indian Journal of Surgery  2012;74(6):504-506.
Cystic malignant pheochromocytomas are uncommon. Differing from solid pheochromocytomas, which produce catecholamines and present adrenergic syndrome, cystic pheochromocytomas, may not produce these. Preoperative diagnosis may be difficult. Ct scan is useful for preoperative management. In this report, we describe a case of a giant malignant cystic pheochromocytoma in a young woman (17 years old) which presented as giant abdominal mass. The malignancy was confirmed by the presence of liver metastasis. Two years after curative resection, the patient is in good health with no recurrence.

2.  Giant Liposarcoma of the Omentum Mimicking an Ovarian Tumor. A Case Report  
The Indian Journal of Surgery  2012;74(5):425-427.
Liposarcomas are common soft tissue of the retroperitoneum and the limbs. They are rarely found in the greater omentum. Once in the peritoneum, these can become enormous and can be mistaken for ovarian mass. The authors report a case of giant omental liposarcoma revealed by an abdominal mass and genital prolapse due to the compression syndrome. A complete macroscopic resection of the omental tumour was performed. A post operative chemotherapy was also prescribed. A description of this clinical presentation in the preoperative assessment, the characteristics of this tumour, together with the use of adjuvant chemotherapy are discussed in this report.

3.  Pancreatic GIST with pancreas divisum: A new entity 
Gastrointestinal stromal tumours (GISTs) are uncommon intra-abdominal tumours. These tumours tend to arise with a higher frequency in the stomach and the small bowel. In fewer than 5% of cases, they originate primarily from extra-gastrointestinal tumours (EGISTs). Gastrointestinal stromal tumour of the pancreas is very rare. Only few cases have been published. We report the first case of stromal tumour of the pancreas with concomitant pancreas divisum.
A 39-year-old male who presented with constipation and abdominal pain. A computerized tomography demonstrated a 9 cm pancreatic mass, without liver lesions. A Whipple procedure with segmental colectomy was performed with success. After 24 months follow up, the patient is doing well and disease-free.
Mesenchymal tumours of the pancreas are extremely rare, accounting for less than 1% of all pancreatic tumours. The endoscopic ultrasound is helpful for diagnosis. Surgical resection with negative pathologic margins remains the treatment of choice.
in our knowledge, this is the first case of pancreatic GIST with pancreas divisum. Although pancreatic GISTs are uncommon tumours, they must be considered in the differential diagnosis of solid pancreatic lesions. Even though the tumour can be evaluated as high risk, treatment must be aggressive in order to improve survival rate.

4.  Giant Trichobezoar of Duodenojejunal Flexure: A Rare Entity 
Bezoars are concretions of undigested material in the gastrointestinal tract, most commonly in the stomach. Duodenojejunal localization of bezoars is exceptional. We report a case of a 27-year-old woman who experienced nausea, vomiting and severe abdominal pain for one week. By palpation a mobile and sensitive mass, 15 × 15 cm, was detected, which filled the upper quadrant. Results of gastric endoscopy were normal. X-ray and ultrasonography suggested a bezoar. A laparotomy revealed that the jejunum was fissured by the trichobezoar ball. This trichobezoar mass was totally excised by intestinal resection.
To our knowledge, this is the first reported case of duodenojejunal fissuration caused by trichobezoar in an adult. Among patients with high subocclusif syndrome, duodenojejunal bezoar should remain a possibility in differential diagnosis.
