Recurrent vulvar malignancies in an 11-year prospectively followed vulvar distrophy: a gynecologist's permanent concern.

This case reports on a vulvar lichen sclerosus, followed during 11 years, with poor response to many different local and general treatments. After 6 years of control the patient developed a mild atypia. Two years later, an invasive carcinoma was diagnosed and radically treated. Six months later, a local recurrence was excised. During the last year of control new biopsies of the neovulva showed, at different times, carcinoma in situ and severe atypia.
