title: Vulval epidermoid cysts in the Igbos of Nigeria.
abstract: Epidermoid cysts are reported to be uncommon on the vulva. However, among the Igbos of Nigeria, the vulva was the most common site of such cysts in a series of specimens examined at a central laboratory. Vulval epidermoid cyssts probably arise as a result of traumatic implantation during ritual circumcision.
