[Sacrococcygeal teratoma. Apropos of 15 cases].

Fifteen cases of sacrococcygeals teratomas were treated at our hospital over the last ten years. There is no correlation between prematuration and tumor weight, as between tumor weight and low babys' weight. High tumoral weight didn't influence the prognosis. The treatment is always surgical. Chemotherapy was used only for recurrence in one case (the patient is dead). For all the cases, we performed a perineal procedure without abdominal procedure. No patient had an abdominal extension of the teratoma.
