title: [Primary adenosquamous carcinoma of the ileum--a case report].
abstract: A 41-year-old woman with a mass of the right lower abdominal quadrant was admitted to our hospital. Ileocecal resection was performed on December 30, 1975; and she is in good health at present. The resected specimen showed a protruded tumor with a central excavation at the terminal ileum; there was a small cyst in the submucosal layer. Histologically, most of the tumor consisted of squamous cell carcinoma. A small nest of squamous metaplasia and adenocarcinoma was observed at the cyst wall. The pathological diagnosis was adenosquamous carcinoma arising from an enterogenous cyst of the ileum.
