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. OBJECTIVE To demonstrate the clinical presentation and management of mature SCT in a neonate. METHODS 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. CONCLUSIONS Mature SCT appear to be entirely benign during the neonatal period. Complete surgical excision remains the mainstay of treatment.

D013724	Teratoma	A true neoplasm composed of a number of different types of tissue, none of which is native to the area in which it occurs. It is composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm. They are classified histologically as mature (benign) or immature (malignant).
