Mature sacrococcygeal teratoma: case report.

Background: Mature sacrococcygeal teratomas (SCT) are uncommon neoplasms comprised of mixed elements derived from the three germ cell layers. They attract attention because of their gross appearance and bizarre histology.
Aim: To demonstrate the clinical presentation and management of mature SCT in a neonate.
Patient and Method: A case report of a neonate with mature SCT is hereby presented.
Results: A 10-day old baby boy presented with a mature SCT comprising well- developed lower limb, rudimentary external genitalia and teeth. He had complete surgical excision (including coccygectomy) with primary wound closure and uneventful postoperative recovery. Follow-up at three years using clinical, biochemical and radiological assessment revealed no evidence of recurrence.
Conclusion: Mature SCT appear to be entirely benign during the neonatal period. Complete surgical excision remains the mainstay of treatment.
