GONADOBLASTOMA AND CHORIOCARCINOMA IN DYSGENIC GONADS - REPORT OF A CASE

Dysgenetic gonads are well known to be associated with gonadoblastoma and various germ cell tumors, but very rarely with choriocarcinoma. Th e describe a 16-year-old, phenotypic female patient with a 46XY karyot ype who developed gonadoblastoma on the light gonad and choriocarcinom a on the left. There was no co-existence of the two tumor cell types i n the same gonad. This case emphasizes the importance of bilateral gon adectomy for ''46XY female'' patients, as soon as the cytogenetic evid ence is known.
