title: Adenosquamous carcinoma of the colon. Case report of an unusual type.
abstract: Primary adenosquamous carcinoma of the colon is a rare entity. Its prevalent site of origin is at the level of the proximal portion of the large bowel. The tumor presents in young patients and follows a highly aggressive course. We present an extremely unusual case of adenosquamous carcinoma in which the classical mucinous and signet-ring cell adenocarcinoma was associated with the squamous component. The prognosis of this rare neoplasm is very poor.
