title: Carcinoma arising in an ileostomy stoma: an unusual complication of adenomatous polyposis coli.
abstract: A patient with adenomatous polyposis coli (APC) without extraintestinal lesions is presented. The clinical course was complicated by rectal adenocarcinoma following subtotal colectomy. A primary adenocarcinoma arising in a villous adenoma within the ileostomy stoma developed seven years later. The varied pathology of gastric and small intestinal involvement in APC/Gardner's syndrome is reviewed. Greater awareness of these lesions has implications for further management.
