VILLOUS ADENOMA OF THE GALLBLADDER - A CASE-REPORT

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 transabd ominal ultrasonography, but CT scan demonstrated a sessile tremor meas uring some 2cm in diameter. A simple cholecystectomy was thus performe d. The resected gallbladder was filled with mucinous material, and sho wed 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 avai lable on villous adenoma of the gallbladder, because such cases are ex tremely rare. In this paper, is described e a rare villous adenoma les ion while paying special attention to the morphological findings.
