Sacrococcygeal teratoma masquerading as congenital hemangioma

Sacrococcygeal teratoma (SCT) is a rare tumor, present in approximately one in 40,000 live births. A small proportion of SCT have malignant potential, so prompt recognition and surgical resection are necessary. We report two cases of SCT initially misdiagnosed as hemangiomas because of their cutaneous appearance and in particular vascular stains overlying soft tissue mass. These two cases emphasize that SCT should be considered in the differential diagnosis of hemangiomas and in particular of congenital hemangiomas.
