title: Adenosquamous carcinoma of the renal pelvis.
abstract: A case of adenosquamous carcinoma of the renal pelvis is reported, associated with multiple staghorn calculi, occurring in a 35-year-old woman. A review of the literature revealed only two previously reported cases. It is postulated that chronic irritation from the renal calculi had induced squamous and glandular metaplasia with subsequent adenosquamous neoplasia.
