RESUMEN
La hidroa vacciniforme (HV) es una fotodermatosis poco frecuente, que usualmente se inicia en la infancia y mejora espontáneamente en la adolescencia. Se caracteriza por la presencia de pápulas, vesículas umbilicadas y costras hemorrágicas en áreas fotoexpuestas, que curan dejando cicatrices varioliformes. La histopatología de las lesiones cutáneas, al igual que la inmunofluorescencia directa, presenta hallazgos característicos pero inespecíficos. El diagnóstico se realiza en base a la correlación clínico-patológica. Recientemente, se ha encontrado una relación entre la HV, el virus de Epstein-Barr y el desarrollo de linfoma. El tratamiento consiste en medidas de fotoprotección, aunque en algunos pacientes se requiere del uso de drogas inmunosupresoras sistémicas
ABSTRACT
Hydroa vacciniforme (HV) is a rare photodermatosis that usually begins in childhood and improves spontaneously in the adolescence. It is characterized by the presence of papules, umbilicated vesicles and hemorrhagic crusts that heal with vacciniform scarring in photoexposed areas. The histopathology of the skin lesions, as well as the direct immunofluorescence findings, is characteristic but nonspecific. The diagnosis is achieved based on clinico-pathological correlation. A relationship between the HV, Epstein-Barr virus and the development of lymphoma has been recently found. The treatment consists of photoprotective measures, but some cases require the use of systemic immunosuppressive drugs
