Abstract
BackgroundSacrococcygeal teratomas are tumors originating from pluripotent embryonic germ cell layers located in the fetal coccyx. These tumors are highly vascular if they undergo malignant transformation. Typically, they are found in infants and children and occasionally can be diagnosed prenatally. Adult cases are very rare, and represent tumors present since birth with delayed detection.Case presentationWe describe a case of a giant sacrococcygeal teratoma in a 25 years old female college student presenting with right gluteal swelling of 4 months’ duration. In addition to the huge disfiguring mass on the perineal area, she also had lower abdominal pain, urinary complaints, and difficulty with ambulation.DiscussionPre-operative impression was of a sacrococcygeal mass and histopathology following complete surgical excision revealed a sacrococcygeal teratoma. She recovered well after surgery with no radiologic evidence of recurrence at six months.ConclusionAlthough rare, sacrococcygeal teratoma should be considered as a differential diagnosis for female adults presenting with perineal and/or pelvic masses. Complete surgical excision remains the mainstay of treatment.

Teratomas are germ cell tumors composed of multiple cell types originating from one or more of the three germ cell layers
Summary
Sacrococcygeal teratomas are tumors originating from pluripotent embryonic germ cell layers located in the fetal coccyx. Discussion: Pre-operative impression was of a sacrococcygeal mass and histopathology following complete surgical excision revealed a sacrococcygeal teratoma. Conclusion: rare, sacrococcygeal teratoma should be considered as a differential diagnosis for female adults presenting with perineal and/or pelvic masses. It is extremely rare to diagnose a sacrococcygeal teratoma in adults and only a few cases have been reported in the literature.
