Neonatal pemphigus vulgaris associated with mild oral pemphigus vulgaris in the mother during pregnancy.

We report a neonate with immunofluorescence-proven pemphigus vulgaris. The condition presented at birth with widespread skin erosions and ulceration of the oral mucosa. Histopathological and immunofluorescence studies confirmed pemphigus vulgaris. The mother had mild oral pemphigus vulgaris treated during pregnancy with topical corticosteroids. All the neonate's skin erosions had crust formation at day 2 but healed completely within 2 weeks.
