1. ERYTHROKERATODERMIA VARIABILIS ET PROGRESSIVA; EKVP
Keratosis Palmoplantaris Transgrediens et Progrediens
Greither disease, also known as keratosis palmoplantaris transgrediens et progrediens, is characterized by nonbullous desquamation of erythematous palms and soles, with hyperhidrosis (Greither, 1952). Gedde-Dahl et al. (1993) showed that manifestations of EKV and of Greither disease coexisted in a Norwegian family. Furthermore, linkage indicated that the disorder was determined by a mutation at the same site on chromosome 1 as EKV.
