Acral blisters in neonates: Three rare and benign diseases.

Exclusive acral involvement in neonatal pemphigus is unusual. Blisters in neonatal bullous pemphigoid, affecting 2%-3% of newborns of mothers with gestational pemphigoid, can be located in the trunk, limbs and acral areas. Unlike neonatal bullous pemphigoid, which can appear up to 5 days after birth, neonatal pemphigus is often revealed at birth. They are benign diseases in newborns. There is no correlation between the disease severity in babies and mothers. Neonatal risk is dominated by the side effects of corticosteroid therapy.
