Vohwinkel's syndrome in three generations.
Vohwinkel's syndrome or keratoderma hereditaria mutilans is a diffuse, honeycombed, palmar, and plantar keratosis usually accompanied by pseudoainhum near the distal interphalangeal creases. The mutilating keratoderma associated with sensorineural hearing loss is thought to have an etiologic basis, resting on a mutation of the GJB2 gene, which encodes the gap junction protein connexin26 (Cx26). This specific mutation results in impaired epidermal differentiation as well as inner ear function. We describe a patient with Vohwinkel's syndrome accompanied by high-frequency sensorineural hearing loss whose mother and son were similarly affected.
