Although sacrococcygeal teratoma cannot be considered a rare tumor, it is sufficiently uncommon that most physicians do not acquire personal experience with this entity. From the calculations of Calhet and Fochier, congenital tumors of the sacrococcygeal region occur once in 34,582 births.3 Teratomas represent only a small percentage of these tumors. To date there are approximately 450 cases described in the literature.
Sacrococcygeal teratomas are recognized at birth in about 90% of the cases. The remainder are seen in older children and, rarely, in adults. At least 75% of the cases have occurred in females. A large percentage of infants with sacrococcygeal teratoma are born dead or die shortly after birth.4
Three cases are presented which highlight the problems of diagnosis and management of these tumors.
