A 76-year-old female with villous adenoma of the gallbladder is herein reported. She presented complaining of upper abdominal pain for some months prior to admission. No tumor mass could be detected by transabdominal ultrasonography, but CT scan demonstrated a sessile tumor measuring some 2 cm in diameter. A simple cholecystectomy was thus performed. The resected gallbladder was filled with mucinous material, and showed a sessile tumor with finger-like processes in the fundus. Both the macro- and microscopical findings of the lesion were almost identical to a typical villous adenoma of the colon. Little information is available on villous adenoma of the gallbladder, because such cases are extremely rare. In this paper, is described e a rare villous adenoma lesion while paying special attention to the morphological findings.
