title: Association of hepatocellular carcinoma and a hyperplastic nodule after phosphate diethylstilbestrol therapy.
abstract: We treated a patient in whom a hepatocellular carcinoma and a hyperplastic nodule of the liver concomitantly grew in association with long term phosphate diethylstilbestrol therapy for a carcinoma of the prostate. A 72-year-old Japanese man was admitted for investigation of hepatic masses. A diagnosis of prostate carcinoma had been made seven years ago and phosphate diethylstilbestrol 200 mg daily had been prescribed. A small mass was first detected in the liver four years later and another mass appeared three years after the appearance of the first mass. Histology of the excised tissue showed the former mass to be a hyperplastic nodule and the latter one hepatocellular carcinoma. Findings of cirrhosis, hepatitis or fibrosis were nil but fatty metamorphosis of the hepatocytes was apparent. These histological changes were considered to be associated with long-term phosphate diethylstilbestrol therapy therefore careful follow-up using amazing diagnosis is recommended for patients on phosphate diethylstilbestrol therapy.
