Hepatic cystadenoma: an unusual presentation.

A 53-yr-old woman with a history of hepatic cystadenoma 25 yr before presented with a simple hepatic cyst, which evolved over 9 yr into a complex cystadenoma with septations and internal bleeding. She was treated with a left hepatectomy. Review of the literature shows that hepatic cystadenomas, although rare, frequently can recur years later and have potential for malignant transformation.

Chronic hepatitis C with normal aminotransferase levels: a clinical histologic study.

Design: Retrospective chart review of all patients encountered during 1-yr with positive hepatitis C antibody (anti-C100-3 ELISA), no alternative cause for their liver disease and PNAL for 6 or more consecutive months prebiopsy. Blinded review of liver histology.
