Bullous disease of childhood.

Bullous disease of childhood (BDC) is a persistent or recurrent blistering skin disease characterized by large, tense bullae in a generalized distribution, but with a predilection for the scalp, trunk, pubis, and inner thighs. It usually begins in the first decade of life and spontaneously remits after several months to three years of activity. Sulfapyridine or dapsone therapy usually controls the disease. Administration of corticosteroids for systemic effects should be avoided.
