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.
