The clinical spectrum of epidermolysis bullosa simplex.
As part of the U.K. National Epidermolysis Bullosa Register, we have systematically recorded clinical information on 130 (77%) of the 168 known Scottish epidermolysis bullosa simplex (EBS) sufferers. Three subtypes of EBS were recognized: Dowling-Meara (EBS-DM), Weber-Cockayne (EBS-WC) and Köbner (EBS-Kb), seen in 5%, 42% and 53% of patients, respectively. As there is considerable overlap between EBS-WC and EBS-Kb, with both phenotypes frequently seen within the same pedigree, EBS-WC is best regarded as a milder variant of EBS-Kb rather than a separate disorder. Improvement with age is common in all variants of EBS, but is not invariable. Pain due to acral blistering in EBS-Kb/EBS-WC has a more marked impact on life-style than the blisters of EBS-DM. Oral blistering, nail involvement and aplasia cutis congenita occur in all EBS subtypes and laryngeal involvement is a feature of EBS-DM. Seasonal variation is not seen in EBS-DM but is common in EBS-Kb/EBS-WC.
