However, if chronic blistering starts in infancy and arises after trauma epidermolysis bullosa is likely. The hands and feet are the most common area to be affected by EB simplex (Weber-Cockayne type). : Dermatitis herpetiformis || Dermatitis herpetiformis is very itchy so the most common presentation is symmetrical excoriated lesions and the primary vesicle may not be evident. Extensor surfaces of elbows and knees, buttocks and scalp are most commonly involved : Bullous pemphigoid ||Bullous pemphigoid presents with widely distributed large tense blisters arising on normal-appearing, erythematous or urticated plaques.
