Transient neonatal Behcet's disease.

A term neonate with a transient form of Behçet's disease (BD) is described. The mother had a 3-year history of BD treated with corticosteroids, which remained in remission during pregnancy. On day 1 of life, the neonate was noted to have papulopustular lesions of the labia and perineum. She remained clinically well and bacterial and viral infection screens were negative. The lesions disappeared within 3 weeks without scarring. No recurrence has been reported.
