Pemphigus vulgaris in a neonate and his mother.

BACKGROUND: Neonatal pemphigus is a rare, transient blistering condition due to transplacental transfer of maternal autoantibodies. CASE CHARACTERISTICS: A male neonate born to a mother with oral pemphigus was noticed to have multiple lesions. OBSERVATION: Multiple flaccid bullae were noticed on the face, scalp, trunk and extremities with clear fluid and few areas of erosions. OUTCOME: All lesions resolved at the end of one week with conservative management. MESSAGE: Maternal pemphigus may rarely involve her newborn infant; it resolves on its own.
