A 4-month-old infant was observed with an acute itchy bullous dermatosis, predominantly involving the extremities, which revealed a dermal infiltrate rich in eosinophils, C3 deposits at the dermalepidermal junction, and circulating antibodies to BP180 antigen, confirming the diagnosis of bullous pemphigoid. He was initially treated with deflazacort 1 mg/kg/day, further increased to 2 mg/ kg/day, followed by reduction over seven weeks with complete clinical resolution within this period. We discuss epidemiology, etiology, relationship with vaccination, clinical features, and treatment of thisrelatively rare bullous dermatosis in the pediatric age.
