Colitis cystica profunda in an adenoma (adenomatous polyp): report of a case.

Abstract

Reference is made to cases in which a frozen-section diagnosis of adenocarcinoma of the colon or doubt has led to a segmental resection for a benign condition (colitis cystica profunda). A case of colitis cystica profunda in an adenoma which was diagnosed and treated as a benign lesion at celiotomy is presented. It is proposed that adenomas may play a role in the pathogenesis of colitis cystica profunda. Fecal irritation of the head of a polyp high in the colon may have the same effect that fecal irritation has in the lower sigmoid colon and rectum.
