[Primary choriocarcinoma of the ovary: a case report].

A case of primary choriocarcinoma of the ovary in a 32-year-old woman, 1 month after a voluntary interruption of pregnancy, is reported. A review of the literature shows that this tumour is rare and the distinction between a gestational and a non-gestational choriocarcinoma is difficult. The distinction between these two diagnoses and specific treatment are discussed.
