Primary duodenal cancer: case report.

Primary carcinoma of the duodenum is uncommonly encountered. This is a report of a 64-year-old diabetic/hypertensive who was admitted in our unit with six months history of upper abdominal pain, vomiting on and off and weight loss of greater than 10 kgs. Endoscopy revealed complete obstruction of the third part of the duodenum. Lesion biopsy revealed moderately differentiated adenocarcinoma and associated duodenitis. A staging CT scan showed thickening of the duodenal wall over a span of six centimetres, luminal narrowing, mucosal irregularity and multiple para-vascular large nodes some greater than or equal to two centimetres. Palliative bypass surgery was suggested as the preferred mode of treatment. He underwent cholecysto-jejunostomy/jejunojejunostomy to palliate biliary and intestinal obstruction.
