title: [Oral contraceptive-induced liver tumors and pregnancy].
abstract: This paper reports on four pregnancies with maternal liver tumors induced by oral contraceptives. No increase in size and no rupture of these liver lesions were observed during the gestational and postpartum period. The toxic potentials of orally active sex steroids and the role of natural sex steroids are discussed. Criteria for differential diagnosis and practical suggestions are presented.
