[Dyshidrosiform bullous pemphigoid].

Dyshydrosiform bullous pemphigoid is a clinical variant of bullous pemphigoid in which the lesions appear primarily on palms and soles. Knowledge of this unusual manifestation of bullous pemphigoid may be of practical relevance, since it has to be included in the differential diagnosis of blistering palmoplantar dermatoses. The correct diagnosis is confirmed by histological examination and immunofluorescence, which reveal all the characteristic hallmarks of bullous pemphigoid. Three patients with dyshydrosiform bullous pemphigoid are presented; clinical and histological aspects, findings on immunofluorescence, differential diagnosis and therapy are discussed.
