[Migratory vulvitis caused by imported gnathostomiasis]. / Vulvitis migratoria causada por gnatostomiasis importada.

Gnathostomiasis is an emerging disease in non-endemic countries. This zoonotic nematode requires aquatic freshwater environments to complete its life cycle where larvae get encrusted in fishes. Typically, the infection manifests as migratory subcutaneous lesion caused by the larvae trak, which produces an eosinophilic panniculitis. Here we describe a patient who presented a migratory lesion with no response to antimicrobial therapy, a careful travel and food history together with specific laboratory tests led to the correct diagnosis. Gnathostomiasis should be suspected in patients with migratory skin lesions who have consumed raw freshwater fish during travel to endemic countries in South America or Asia.

Vulvitis migratoria causada por gnatostomiasis importada / Migratory vulvitis caused by imported gnathostomiasis

Resumen La gnatostomiasis es una parasitosis emergente en países no endémicos. Este nematodo zoonótico requiere de agua dulce para su ciclo de vida, donde sus larvas se enquistan principalmente en peces. La migración subcutánea de las larvas produce habitualmente una paniculitis eosinofílica de rápido avance. Se describe un caso clínico de un paciente con una lesión migratoria, sin mejoría clínica con terapia antibacteriana. La búsqueda de factores de riesgo, sumado a la evolución y a los hallazgos de laboratorio hizo sospechar el diagnóstico. La gnatostomiasis debe ser sospechado en pacientes con lesiones de piel migratorias, que han consumido pescado crudo durante viajes a países endémicos en Sudamérica o Asia.

Zoon vulvitis.

Zoon vulvitis or vulvitis chronica plasmacellularis is a rare, chronic benign inflammation of the vulvar mucosa, diagnosed histologically, with variable therapeutic responses. It is important to be diagnosed because it mimics the presentation of other genital conditions, such as lichen planus and squamous cell carcinoma, which require specific treatment. We report a case of a female patient with three asymptomatic shallow ulcers on the labia minora. Laboratory tests ruled out infectious diseases and the biopsy was consistent with Zoon Vulvitis.

Vulvitis de Zoon: caso clínico / Zoon vulvitis: clinical case

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.

Zoon vulvitis as a differential diagnosis in an HIV-infected patient: a short report.

Vulvitis circumscripta plasmacellularis or Zoon vulvitis is a rare benign condition that affects the vulva chronically. We herein report a case of Zoon vulvitis in a 52-year-old HIV-infected patient with an uncommon ulcerovegetating lesion diagnosed by histopathologic findings. The patient was treated with clobetasol propionate ointment and oral corticosteroid. Zoon vulvitisis is a rare vulvar disorder that offers a challenging diagnose and therapy. The patient was appropriately treated and remains disease free.

Vulvitis de Zoon / Zoon´s vulvitis

La vulvitis de Zoon fue descripta por primera vez por Zoon y Garnier en 1954. Se trata de una inflamación crónica de la mucosa vaginal, de baja incidencia. La etiopatogenia es desconocida y hasta la fecha no hay descripto ningún tratamiento efectivo. Las características clínicas e histopatológicas remedan su contrapartida masculina, la clásica balanitis circunscripta plasmocelular o de Zoon.

Zoon´s vulvitis was first described by Zoon and Garnier in 1954. It´s a low- prevalence, chronicinflammation of the vaginal mucosa. The etiology is unknown, and an effective standardtreatment has not yet been described. Its clinical and histophatologic features resemble the malecounterpart known as Zoon´s balanitis.

Distrofias vulvares: aspectos clínicos e anatomopatológicos / Vulvar dyatrophies: clinical and anatomopathological aspects

Foram revistas 80 biópsias referentes às chamadas "lesöes brancas da vulva", obedecendo-se aos critérios histológicos preconizados pela Sociedade Internacional para o Estudo da Patologia Vulvar, com a finalidade de observar os achados histológicos mais freqüentes e uniformizar a terminologia utilizada. Depuradas 11 biópsias que näo se enquadraram nos critérios estabelecidos para o diagnóstico de distrofia vulvar, restaram 69 correspondentes a 53 pacientes que haviam sido submetidas a uma ou mais biópsias vulvares no decorrer da evoluçäo da lesäo. Das 53 pacientes, 29 (54,7%) eram portadoras de distrofia hiperplásica, sendo 7 com atipias celulares de grau leve e 2 de grau moderado. O LEA esteve presente em 22 casos (41,5%) e a distrofia mista em apenas 2 casos (3,7%), sendo ambos sem atipias. Foram analisados os aspectos clínicos e histopatológicos encontrados nestas lesöes, sendo que dos 50,9% dos casos, onde a proservaçäo foi superior a um ano, observamos que a evoluçäo para o carcinoma vulvar ocorreu em duas pacientes (5,7%), sendo que se tratavam de distrofias hiperplásicas, sem atipias em uma delas e com atipia moderada em outra. Conclui-se pela necessidade de estabelecer-se um diagnóstico através da biópsia vulvar e estudo histopatológico preciso, devido à potencialidade maligna destas lesöes, sendo necessário uniformizar a terminologia e promover uma maior integraçäo entre o tocoginecologista e o patologista
