Perforation of jejunal non Hodgkin's lymphoma.

Primary gastrointestinal lymphomas are rare. Jejunal non Hodgkin's lymphoma presenting as perforative peritonitis is extremely rare. We report a 51-year-old man who presented with perforative peritonitis and was detected to have jejunal non Hodgkin's lymphoma. He was treated with resection of the affected segment with its mesentery and postoperative chemotherapy, and was asymptomatic 5 months later.
