title: An infant with bullous pemphigoid.
abstract: Bullous pemphigoid is the most common subepidermal autoimmune blistering disease. However, it is very rare in the pediatric population. A 5-month-old male infant presented with multiple bullae located on palms and soles. Complete blood count revealed relative eosinophilia . A biopsy revealed a subepidermal blister present along with a dermal mononuclear infiltrate rich in eosinophils. In focal areas collagen flame figures, were also observed. Direct immunofluorescence showed linear reactivity for C3c and IgG at the dermal-epidermal junction. IgA was not found. Complete resolution was achieved after oral deflazacort (1.5mg/kg/day) with progressive dose reduction over 2 weeks. Bullous pemphigoid is extremely rare in the infant. In our case the disease presented with an unusual localized (acral) clinical distribution and a favorable outcome.
