Colonic non-hodgkin lymphoma presenting as splenomegaly splenocolic fistula in person living with HIV: A case report

Primary colonic lymphoma is an infrequent malignancy among other large bowel malignancies, and the risk of the spread of tumor cells through a spleno-colic fistula is a unique finding and hence noteworthy. We report a case of a 55-year-old man living with HIV on anti-retroviral treatment for 12 years, who presented to the emergency room with complaints of generalized weakness and left-sided abdominal discomfort. Further examination and evaluation revealed massive splenomegaly with a thickened splenic flexure of the colon and spleno-colic fistula. The diagnosis of lymphoma with spread was made following laparotomy and histopathological examination of the colon and spleen.
