Case report: plexiform schwannoma of the vulva.

We describe a case of plexiform schwannoma, a benign tumour of the peripheral nerve sheath, arising in the labia of a 5-year-old girl who presented with a mass in the vulva. Light and electron microscopy, special stains and immunohistochemistry studies were done on the excised specimen. A Medline search revealed a single case of vulvar plexiform schwannoma which was reported in 1983.
