[Two cases of benign liver tumour in women on oral contraceptives (author's transl)].

Two benign liver tumours are described in women who had taken oral contraceptives. These were cases of focal nodular hyperplasia and a liver cell adenoma. These lesions are benign, and were discovered on routine examination as they were not responsible for any clinical sign, as is usual except in cases of peritoneal rupture, where the patient presents with a dramatic hemoperitoneum. Oral contraceptive were found to be associated as in many recent cases. Oestro-progestins were found to be responsible for an increase in hepatic metabolism, which gave rise to biochemical, histological and sometimes clinical changes in the form of jaundice or a tumour. There is no proof of this mechanism but the supervision of women on contraceptives should include a search for a hepatic tumour for which surgical treatment is necessary to prevent complications.
