High-grade GI lymphoma presenting with diarrhoea.

A 63-year-old male carpenter presented with diarrhoea after returning from a holiday in Egypt with no other abdominal features. Physical examination showed generalised lymphadenopathy and splenomegaly. Blood tests including inflammatory markers were within normal limits. Microbiological stool sample analysis was unremarkable. Endoscopies of the large bowel showed patchy inflammation from the rectum to the hepatic flexure with multiple tiny polyps. Histology revealed a lymphocytic infiltrate suggestive of multiple lymphomatous polyposis. Some time later, he presented with small bowel obstruction requiring emergency laparotomy and ileostomy. After recovery from surgery he started definite treatment with chemotherapy resulting in complete remission.
