Gluteal teratoma: A rare site of extragonadal teratoma

Abstract

Extragonadal teratomas are rarely encountered in infants and children. These tumors are reported in retroperitoneum, floor of the mouth, mediastinum, craniofacial region or even in the solid organs of the body. Most of the gluteal teratomas reported in the literature are in fact, lateralized sacrococcygeal teratomas. We are reporting a case of unilateral big gluteal teratoma in a 6-year-old girl. The tumor did not have any connection with the sacrum or coccyx and was successfully removed. Histology showed well-differentiated bowel as well as fetiform structures.

Gluteus as a rare localization of extragonadal teratoma

“…To the best of our knowledge, there is just one case in the literature of a gluteal teratoma not in connection with the coccyx, as in our patient, thus confirming the possibility of this very rare localization. 10 The biological mechanism for germ cell migration to such anatomical regions is still to be elucidated.…”

Gluteal teratoma: An atypical presentation in a 2-year-old girl

“…The most commonly reported gluteal teratomas in the literature are lateralised sacrococcygeal teratomas. [1] These tumours derive from more than one embryonic germ cell layer, and are usually diagnosed in infancy. [2] The estimated incidence of presacral teratomas in children ranges from 1 in 30 000 to 1 in 43 000 live births.…”
