Genital prolapse in a newborn following resection of sacrococcygeal teratoma.

Neonatal genital prolapse usually occurs during the first few days of life and presents as a tumor mass protruding from the vulva. We present a 15-day-old female neonate who developed neonatal genital prolapse following the operation of sacral teratoma. We suggest that sacral teratoma operation may be a significant predisposing factor for genital prolapse in neonates and the neonatal vaginal prolapse may be one of the differential diagnoses of interlabial mass during the late neonatal period.
