Primary adenocarcinoma of the ileostomy after colectomy for ulcerative colitis.

Abstract

A fifth case of adenocarcinoma arising at an ileostomy site many years after total colectomy for ulcerative colitis is reported with a review of the literature. The patient is a 79-year-old white man who presented with a bleeding, locally invasive exophytic mass at his ileostomy site 36 years after total colectomy for ulcerative colitis; he is the oldest patient, with the longest interval from creation of his ileostomy to diagnosis of adenocarcinoma. Careful gross and histopathologic examination of any mass arising at an ileostomy site is recommended. Early detection of such a slowly growing malignancy arising in a long-standing ileostomy may result in cure.
