Congenital vulvar teratoma in a newborn.

The most common site of teratomas in neonates is in the sacrococcygeal region. Herein the authors describe a congenital teratoma, and to their knowledge it is the first reported case of vulvar site in a newborn. Tumor was removed on the fourth day of life, and she was completely normal 18 months after the operation. Because of possible malignancy or recurrence, complete surgical excision of the tumor and careful follow-up is the treatment of choice. J Pediatr Surg 36:620-621.
