Congenital vulvar lipoma within an accessory labioscrotal fold.

Perineal lipomas are uncommon congenital anomalies. They mainly develop in male patients with an accessory scrotum, posterior to the original scrotum. However, on rare occasions, these lipomas can occur in female patients with an accessory labioscrotal fold. We report on three such cases, where the lipomas were found in the anterior part of the right side of the labia majora. None had other anomalies, with the exception of one who had premature growth of pubic hair on the accessory labioscrotal fold. Skin with a rugated scrotal appearance was present in all cases.
