Adenomatous hyperplasia of the liver.

An unusual case of adenomatous hyperplasia of the liver arose spontaneously in an 82-year-old woman. Massive fatal ascites developed during an eight-week period in the absence of cirrhosis. No drug, chemical, or hormone could be identified as the causative agent. Estrogens may play a role as possible promoters in the growth of hepatic tumors. Identifying liver tumors in women that are not associated with oral contraceptive use is valuable.
