Rare presentation of sacrococcygeal teratoma in a prepubertal girl

Abstract

Eighty-five percent of sacrococcygeal teratomas, the most common neonatal tumor present in infancy with externally visible swelling. Because of associated risk of malignancy, which increases exponentially with age, majority of the tumors undergo operative intervention. Hence, presentation in an adult that too of a benign mass is extremely rare, with less than 10 reported cases in world literature. We report case of a 9-year-old girl who presented with swelling in the gluteal cleft. Excision of the swelling along with the coccyx was done. Benign cystic sacrococcygeal teratoma was diagnosed on histopathological evaluation of the excised tumor mass. This case is reported for a very unusual presentation of sacrococcygeal teratoma and also brings forth the difficulties encountered during excision of the tumor.
