title: Liver hamartomas in patients on oral contraceptives.
abstract: Three cases are reported of tumour-like lesions of the liver in women who had been on oral contraceptives for long periods. These malformations have a prominent vascular component and may present with haemoperitoneum and shock. The possibility of an association between liver hamartomas and oral contraceptive therapy has to be considered.
