We report an 8-year-old boy with a primary subcutaneous sacrococcygeal
ependymoma, a rare tumor that is thought to arise in embryologic rest

owed without recurrence for 20 months. Our experience, together with t
hat of the other 15 cases in the world literature, supports surgical e
xcision as the mainstay of treatment. (C) 1998 Wiley-Liss, Inc.
