[Delivery following surgically treated sacrococcygeal teratoma in the mother].

The delivery of a 23 para I who was born herself with a sacrococcygeal teratoma of the type II is reported. After the extirpation of the tumor and of the coccyx an anomaly of the pelvis is found in the sense of a pygopagic pelvis (stretching and bending of the sacrum towards the dorsum). This anomaly and the scars in the way of a maternal soft tissue dystocia seem to be the reasons for the insufficient progression of labour. The delivery had to be done by caesarean section. A historical review concerning the surgery of sacrococcygeal teratomas is given.
