Mixed adenosquamous carcinoma of the cecum: report of a case and review of the literature.

Abstract

A case of mixed adenocarcinomatous and squamous carcinomatous tumor of the cecum is reported. The squamous elements present in the tumor had all the criteria of malignancy and not of simple squamous metaplasia (as in adenoacanthoma). The term mixed adenosquamous carcinoma should therefore connote such a tumor.
