[Hyperplastic lesions and benign tumours associated with oral contraception. Report of ten cases (author's transl)].

The article reports on 10 cases of benign liver tumors associated to OC (oral contraception): 7 cases of focal nodular hyperplasia 2 cases of adenomas and 1 case with both lesions present. In all cases OC treatment had been continued for at least 5 years. Hemorrhages were often associated with adenomas but not always. Symptomatology of hepatic lesions is often very vague; biological data can at time suggest cholestasis. Echography is helpful but angiography is still the most precise diagnostic tool. Such lesions are rare but they must be taken into consideration when OC is prolonged. (Summary in ENG)
