Heterotopic Pancreas: Unusual Cause of Usual Diarrhoea.

Heterotopic pancreas (HP) also known as ectopic pancreas, pancreatic crest or accessory pancreas is the normal pancreatic tissue, found in a remote area other than its natural location, with no anatomic or vascular connection to main pancreatic tissue. It is a rare congenital anomaly and has been reported at many locations such as stomach (antrum) and small intestine. HP is usually an incidental finding and asymptomatic, however there are reports of pancreatitis, obstruction, perforation and malignant transformation as uncommon manifestations. Diagnosis of HP is primarily based on histological examination either by biopsy or surgical excision. Surgery is the standard treatment for symptomatic HP patients. Herein, we present a case of a 58-year-old female, who presented to us with intractable diarrhoea due to HP in the jejunum and underwent minimally invasive surgery for definitive diagnosis and treatment.

Gastric Schwannoma-Two Unusual Cases with Usual Presentation and Review of Literature.

Schwannomas, also known as neurilemmomas, are characteristically benign, slow growing neoplasms originating from Schwann cell sheath. Gastrointestinal schwannomas are very rare with stomach being the most affected organ representing approximately 0.2% of all gastric tumours. Malignant transformation is rarely reported in these tumors and complete surgical resection with negative margins is the recommended treatment. Herein, we report our experience of 2 cases of gastric submucosal spindle cell tumour (SMT), which were preoperatively assumed to be as gastrointestinal stromal tumor (GIST), however postoperatively confirmed as schwannoma on immunohistochemical examination.
