[Adenocarcinoma at an ileostomy site after colectomy for ulcerative colitis].

In this article we present the tenth case, according to the literature, of adenocarcinoma occurring at a long standing ileostomy originally performed for ulcerative colitis. Study of this and previous cases demonstrates common factors such as a previous history of ulcerative colitis, a long interval until the appearance of symptoms, together with a similar clinical and pathological characterisation with invasion of neighbouring skin layers close to the ileostomy. Several pathogenic hypotheses are considered. We believe that local excision in oder to obtain the diagnosis is a better option than a sampling biopsy and that surgery should include a wide resection of the abdominal wall and intestine in order to comply with therapeutic criteria in malignant disease.
