O Hidroa Vaciniforme é uma fotodermatose muito rara vista geralmente na infância. Uma paciente de 18 anos foi examinada, a qual apresenta lesões vesiculosas e necróticas varioliformes nas áreas fotoexpostas, que evoluem para cicatrizes atróficas, piorando no verão. A microscopia óptica mostrou necrose epidérmica com infiltrado linfocítico. Houve pouca melhora com uso de filtros solares.
