title: Presacral teratoma in the adult.
abstract: Sacrococcygeal teratomas are unusual tumors in children, and are extremely rare in adults.  A review of the literature has revealed 69 reported cases of presacral teratomas in adults, and an additional two cases are presented, one in association with a meningocoele.  Surgical excision is the treatment of choice.  Malignant changes were noted in 11 per cent of cases.
