An 11-year-old boy presented with a nasopharyngeal mass that was thought to represent a juvenile angiofibroma based on the initial clinical and radiological evaluation. Partial tumour resection was performed. Resected specimen revealed histological diagnosis of undifferentiated carcinoma. Further evaluation of the tumour including MR imaging, radioisotope bone scan, CT thorax and abdomen were performed. Differential diagnoses of childhood nasopharyngeal masses were discussed. The differences between childhood NPC and adult NPC, rhabdomyosarcoma, malignant lymphoma and juvenile nasopharyngeal angiofibroma were also discussed.

Gallstone spillage during laparoscopic cholecystectomy is a relatively common occurrence. These intraperitoneal stones rarely give rise to complications. We present the case of a 68 female who presented with a 5 cm diameter epigastric mass two years after a laparoscopic cholecystectomy for acute-on-chronic cholecystitis with gallbladder stones. CT abdomen demonstrated an inflammatory mass with central calcification. Laparotomy and excision of the mass revealed the diagnosis as a gallstone granuloma.

Gastric stump carcinoma is a carcinoma arising in the stomach remnant following previous gastric resection. It is a distinct disease entity with its unique aetiology and pathogenesis. We report 3 cases of gastric stump carcinoma encountered in the department over the past 5 years and review current literature pertaining to its clinical presentation, aetiology, pathogenesis, treatment strategy and the role of screening endoscopy. The disease is characterised by its late presentation and dismal prognosis and will continue to pose a surgical challenge in the years to come.

Intrahernial tumour is an uncommon entity. Up to 1980, there are 23 reported cases of primary intrahernial tumours. Suspicion should arise when a longstanding hernia has recently become incarcerated. This is the first reported case of primary tumour of the transverse colon found within a paraumbilical hernia presenting with obstruction.
