Desquamative vaginitis: lichen planus in disguise.

A principal cause of desquamative vaginitis is erosive lichen planus. We report five cases to illustrate the classic oral and vaginal findings, describe the histology, and relate the therapeutic response of the disease. Early recognition of the disorder and prompt use of corticosteroids and vaginal dilators may prevent the common sequelae of adhesion formation and vaginal stenosis.
