Intra-abdominal (Type IV) sacrococcygeal teratoma presenting with buttock hemangioma

Sacrococcygeal teratoma is the most common type of extragonadal germ cell tumor in infants and young children. Sacrococcygeal teratomas can uncommonly present in an intra-abdominal fashion, with minimal clinical findings. Dermatologic lesions overlying the vertebrae or buttocks are often associated with sacrococcygeal teratoma and may be the only clue to their presence. Here, we report a case of an intra-abdominal sacrococcygeal teratoma presenting with an anatomically separate buttock hemangioma.
