Vulvitis plasmocitaria circunscrita de Zoon. A propósito de un caso

espanolLa vulvitis circunscrita de Zoon es una entidad benigna descrita por Garnier en 1954. La patogenesis es desconocida; se postulan factores predisponentes como infecciones cronicas, sudoracion excesiva, pobre higiene y trauma, que desencadenan una respuesta inflamatoria o inmune. Se presenta a una paciente de 67 anos de edad con diagnostico de vulvitis circunscrita de Zoon. Se describe el caso por su escasa frecuencia. Es preciso remarcar que es indispensable el estudio histopatologico para su diagnostico y la buena respuesta terapeutica con clobetasol topico. Es necesario hacer un diagnostico diferencial con otras entidades como ETS, cuadros dermatologicos, enfermedades sistemicas (LES, Crohn, Behcet) e, incluso, lesiones precancerosas o carcinomas. EnglishZoon’s vulvitis is a benign entity described by Garnier in 1954. Its precise incidence is unknown, as well as its etiopathogenesis, although a variety of triggering factors have been suspected such as chronic infections, excessive sweating, poor hygiene, and trauma. We present the clinical case of a 67-year-old patient with a diagnosis of vulvitis circumscripta plasmacellularis (Zoon’s). The case is presented because of its low frequency and good response with topical clobetasol. The histopathology is important for diagnosis; a differential diagnosis is necessary with other entities such as STDs, dermatological and systemic diseases (SLE, Crohn’s disease, Behcet), and even precancerous lesions or carcinomas.
