[Surgical management of presacral sacrococcygeal teratomas, or with intrapelvic extension].

Two cases of sacrococcygeal teratomas that were successfully treated surgically through the abdominosacral route are reported. Besides, a series of 36 children diagnosed through a period of 30 years is reviewed and considerations are made on the importance the classification of teratomas has, to choose the best route of approach for the surgical removal of these tumors. Mention is made of symptoms that allow the diagnosis of presacral teratomas and of those that show intrapelvic or abdominal extension.
