[Bullous angiolymphoid hyperplasia with eosinophilia]

Two patients are described having a bullous variant of angiolymphoid hyperplasia with eosinophilia on the head. This disease is characterized by inflammatory, infiltrated, plaque-like lesions with recurring bullous eruptions. At the same time there may be prurigo-like papules on the trunk and arms. The course is a characteristic histological pattern revealing cutaneous lymphocytic infiltrate, lymphoid follicle formation, and atypical vascular proliferation associated with tissue eosinophilia. Blister formation takes place subepidermally.
