ABSTRACT
Phaeohyphomycosis is a disease caused by dematiaceous fungi with a worldwide geographic distribution and broad spectrum. It is most commonly found in adult individuals of both genders and all races. We report the case of a 57-year-old woman with phaeohyphomycosis in the ungual apparatus.

Vohwinkel syndrome or keratoderma hereditaria mutilans is a rare autosomal dominant palmoplantar keratosis, which manifests in infants and becomes more evident in adulthood. Its mode of inheritance is autosomal dominant with mutation in loricrin and Connexin 26 genes. Patients with this mutation present hyperkeratosis of the palms and soles, constricting bands of the digits, usually on the fifth, and starfish-shaped hyperkeratosis on the dorsal aspects of the hands and feet. The disease mostly occurs in white women, where constricting fibrous bands appear on the digits and can lead to progressive strangulation and auto-amputation (pseudo-ain-hum).The authors report a rare case of a patient with a clinical ichthyosiform variant of Vohwinkel syndrome.
A síndrome de Vohwinkel ou queratodermia hereditária mutilante é uma queratose palmo-plantar rara, autossômica dominante, que se manifesta em crianças e se torna mais evidente na vida adulta. Seu modo de herança é autossômica dominante com mutação na loricrina e no gen da Conexina 26. Os pacientes com esta mutação apresentam hiperqueratose das palmas das mãos e plantas dos pés, com bandas constritivas dos dígitos, normalmente no quinto dedo e hiperqueratose em forma de estrela do mar nas regiões dorsais das mãos e dos pés. A doença ocorre principalmente em mulheres brancas, onde as bandas constritivas fibrosas aparecerem nos dígitos e podem levar ao estrangulamento progressivo e auto-amputação (pseudo-ainhum).Os autores relatam o caso de uma variante ictiosiforme da síndrome de Vohwinkel.
