Postvaccination Bullous Pemphigoid in Infancy: Report of Three New Cases and Literature Review



Bullous pemphigoid (BP) is an acquired autoimmune blistering disorder of unknown etiology uncommon in childhood. Unlike adult BP, infantile BP shows acral distribution and resolves rapidly with systemic steroids. We report three infants with infantile BP presenting shortly after vaccination for diphtheria, pertussis, tetanus, poliomyelitis, hepatitis B, Haemophilus influenzae B, and meningococcus C. Our cases further reinforce the causal association between childhood BP and vaccination.
