%X La asociaci車n de psoriasis y vitiligo es un evento bien documentado, con una incidencia del 3%, seg迆n diferentes series de casos, aunque no hallamos trabajos de superposici車n de ambas enfermedades siguiendo las l赤neas de Blaschko, en la literatura revisada por nosotros. Presentamos el caso de una mujer de 47 a os de edad con lesiones de vitiligo en rostro y en abdomen, desde la infancia, que se distribuyeron sobre las l赤neas de Blaschko; despu谷s de 30 a os aparecieron placas eritematoescamosas sobre las manchas acr車micas del abdomen, que cl赤nica e histopatol車gicamente correspondieron a psoriasis y mejoraron parcialmente con fototerapia UVB de banda estrecha. La psoriasis y el vitiligo son entidades multifactoriales, polig谷nicas, que pueden exhibir patrones de mosaicismo cut芍neo. Se han planteado algunas teor赤as para explicar este fen車meno, pero todav赤a no son conocidos todos los factores que influyen en este tipo de presentaci車n. The association of psoriasis and vitiligo is a well documented event, with an incidence of 3% according to different case series, but reports of an overlap of both diseases following Blaschko lines were not found in the reviewed literature. We present the case of a 47 years old woman with vitiligo lesions in the face and abdomen, starting since childhood, distributed over the Blaschko lines; thirty years later erythematous and squamous plaques appeared over the achromic macules of the abdominal region which were clinically and histopathologically compatible with psoriasis and improved partially with narrow band UVB phototherapy. Psoriasis and vit赤ligo are multifactorial and polygenic skin disorders that can show patterns of cutaneous mosaicism. Some theories have tried to explain this phenomenon, but the factors that influence this presentation are still unclear.
