title: Testosterone metabolism in basal cell epitheliomas.
abstract: In basal cell epitheliomas the testosterone metabolism pattern differs from that of the normal surrounding skin. There is a significant reduction in 5 alpha-reductase activity with a consequent decrease in production of dihydrotestosterone and androstanediols. By contrast the 17 beta-hydroxysteroid dehydrogenase activity shows no consistent change.
