RESUMO
RESUMEN La vulvitis de Zoon o vulvitis de células plasmáticas es una enfermedad inflamatoria crónica infrecuente, caracterizada por placas eritematosas bien delimitadas y brillantes que pueden afectar cualquier localización de la vulva. Suele presentarse en mujeres posmenopáusicas y plantea un difícil diagnóstico diferencial. Se insiste en la necesidad de realizar biopsia vulvar para obtener un diagnóstico histológico de certeza. Se presenta el caso de una paciente de 36 años y se comenta las opciones terapéuticas actuales descritas en la literatura.
ABSTRACT Zoon vulvitis or vulvitis circumscripta plasmacellularis is a rare chronic inflammatory disease characterized by well-delimited and shiny erythematous plaques that can affect any location of the vulva. It usually occurs in postmenopausal women and poses a difficult differential diagnosis. The need for a vulvar biopsy is emphasized to obtain a certain histological diagnosis. The case of a 36-year-old patient is presented and the current therapeutic options described in the literature are discussed.
RESUMO
Se presenta un caso de una paciente de 84 años con vulvitis de Zoon. Se trata de una dermatosis vulvar de etiología incierta, muy poco frecuente, que ocasiona sintomatología inespecífica de prurito y escozor vulvar de larga evolución, acompañados de una o varias lesiones focales circunscritas y eritematosas de difícil diagnóstico clínico. Se insiste en la necesidad de realización de biopsia vulvar para obtención de un diagnóstico histológico de certeza. Se comentan las opciones terapéuticas actuales descritas en la literatura aunque no existe un tratamiento de elección.
An 84 year old female patient with Zoons vulvitis case is reported. It is a rare vulvar dermatosis of unknown etiology, with unspecific symptoms such as pruritus and vulvar stinging, both developed over a long period of time, accompanied with focal erythematous injuries. As a clinical diagnosis remains difficult, it is essential that a biopsy is obtained for accurate histological diagnosis. Despite different therapeutic options available, there is no consensus on a standardized treatment.

We present a 40-year-old woman who had a well circumscribed, pea sized red-brown glistening erosive papule on the foreskin of clitoris for four months which had been resistant to various forms of treatment. Histopathologic examination revealed flattened epidermis with lozenge keratinocytes and watery spongiosis, In the upper dermis, dense bandlike infiltration of plasma cells, endothelial proliferation, and capillary dilatation were noted. Peroxidase-antiperoxidase stain showed polyclonal pattern of reaction in the cytoplasm of plasma cells.
