Oestrogen receptors in focal nodular hyperplasia of the liver

Two patients with focal nodular hyperplasia of the liver and positive results of tests of oestrogen receptor status are described. Both patients were women, both had used oral contraceptive agents and in both the lesion was symptomatic and was surgically resected. The biological and potential therapeutic implications of positive results of tests of oestrogen receptor status in focal nodular hyperplasia is discussed.
