Neonatal sucking blisters.

A female neonate was born by nontraumatic vaginal delivery at 41 weeks gestation to a 26-year-old caucasian woman following uncomplicated pregnancy. The mother denied any history of syphilis, herpes simplex infection, lupus erythematosus, autoimmune or hereditary bullous disorders. Examination approximately 2 hours postpartum revealed an active neonate with two superficial round erosions measuring 1 cm along the distal radial aspect of the left wrist (Fig 1). No other skin abnormalities were detected. During the examination the infant started to suck vigorously at the involved areas. The erosions healed uneventfully without any treatment after several days.
