Clear Cell Adenocarcinoma of the Urinary Bladder

Abstract

Clear cell adenocarcinoma of the lower urinary tract, and particularly of the bladder, is a rare neoplasm and its histogenesis remains obscure. The authors report the clinical and pathologic findings of a 55-year-old male with clear cell carcinoma of the bladder. The histogenesis of the tumor is discussed, and 35 cases reported in the literature are reviewed.
