A 42-year-old woman with a history of cholangiocarcinoma on adjuvant chemotherapy with capecitabine presented with painless haematochezia. She was found to have an isolated twenty-five mm ulcer in the ascending colon. Biopsies of the ulceration demonstrated typical cytomegalovirus (CMV) inclusions and her peripheral blood CMV PCR was significantly elevated. This is an unusual case of a solitary proximal colon ulcer. Non-steroidal anti-inflammatory drugs, inflammatory bowel disease and malignancy, are the most frequent causes of isolated ulcers in the proximal colon. Gastrointestinal (GI) CMV disease most commonly causes CMV colitis and is considered rare outside of the transplant population and other severely immunosuppressed patient groups. Patients who have received chemotherapy may also be at risk for GI CMV disease. The diagnosis should be suspected in patients who present with haematochezia or watery diarrhoea within a broad window of time after receiving chemotherapy.
