Hyperplasia and prolapse of hepatocytes into hepatic veins during longterm methyltestosterone therapy: possible relationships of these changes to the developement of peliosis hepatis and liver tumours.

Abstract

We report the pathological changes in liver biopsies from 10 patients (four female transexuals and six impotent males) after treatment with 150 mg methyltestosterone daily for periods of up to 3 years, and in a hemihepatectomy specimen from a female transexual who developed a liver adenoma after 37 months of this treatment. Hepatocyte hyperplasia and mild focal sinusoidal dilatation was found in most cases. In some cases there were microcysts and dissociation of hepatocytes. In nine patients there was accumulation of hepatocytes between the endothelium and the supporting collagen of hepatic veins which often resulted in either partial occlusion of their lumina or disruption of their walls. These vascular changes do not appear to have been reported before. It is postulated that a single pathological process-hyperplasia, perhaps related to the anabolic effect of methyltestosterone--could be partly responsible both for the formation of cysts through mechanical obstruction of hepatic veins and for the formation of nodules and tumours.
