Background: Pemphigoid gestations is very seldom responsible for cutaneous lesions in newborns through passive transfer of the autoimmune disease from mother to infant.
Case report: We report an additional case of a newborn presenting with an extensive but transitory bullous eruption despite the absence of circulating autoantibodies.
Conclusion: Such examples of transplacental pemphigoid are so uncommon that the pathogenic role of IgG autoantibodies is being questioned.
