Vulvitis circumscripta plasmacellularis (Zoon's vulvitis) associated with autoimmune polyglandular endocrine failure

Abstract

Vulvitis circumscripta plasmacellularis (Zoon's vulvitis) is a distinct clinicopathological entity which presents as a shiny, atrophic, erythematous plaque of the vulva. It is an idiopathic condition with characteristic clinical and histological findings that generally occur in isolation of other medical disorders. We report a 36-year-old woman with vulvitis circumscripta plasmacellularis associated with polyglandular endocrine failure and circulating autoimmune antibodies. The association between Zoon's vulvitis and these autoimmune conditions raises the possibility that Zoon's vulvitis may be an autoimmune disorder.
