[Benign tumours of the liver and oral contraceptives (author's transl)]

Abstract

The pathologic features, the terminology, the etiolgoy, and the causal relations of benign tumours of the liver associated with the use of oral contraceptives were reviewed during a study on six new cases. According to the literature the following points are emphasized: these tumours can be divided into two distinctive conditions, they are commonly called focal nodular hyperplasia and liver cell adenoma, whereas the name hamartoma seems rarely appropriated, they occur without any use of oral contraceptive, but this practice is probably responsible for their increasing number.
