[Primary carcinoma of the liver and long-term administration of oral contraceptives followed by pregnancy (author's transl)].

A 32-year-old woman who had taken oral contraceptives for seven years, became pregnant after omitting the drug and had a normal child. Soon after a malignant hepatic tumour became apparent of which she died after three months. The tumour was a hepatocellular carcinoma, of low differentiation under the electron microscope. The tumour cells contained fibrils similar to alcoholic hyaline. A review of published reports suggests the possibility that the oral contraceptives and the hormonal influence of the pregnancy together played an important role in the development of the malignant tumour.
