Abstract
On colonoscopy, the macroscopic aspect of a lesion is an important criterio n for the differential diagnosis. We present a case of an apparently malign ant tumor in the sigmoid. Histological investigation failed to support the diagnosis made from the gross appearance seen on colonoscopy. After surgica l resection, the lesion turned out to be a reactive pseudotumor caused by f ibroepithelial hyperplasia related to a severe diverticulitis with perforat ion of the intestinal wall.
