Incontinentia Pigmenti. Presented by Dr. Melvin Gelfarb (by invitation), Bellevue Hospital.
History.—
An infant girl, now 5 months old, was delivered uneventfully. Two days after the child was born, the mother noted red spots on the baby's buttocks and scalp, and 5 days later she saw warty lesions on the fingers and thighs. The infant was seen when she was 3 weeks old. She then showed erythematous verrucous papules in linear patterns on the buttocks, thighs, and upper portions of the arms. At 4 weeks similar lesions appeared on the fingers, toes, ankles, and chest. At 5 weeks the lesions on the chest were seen to be resolving, leaving behind linear streaks of hyperpigmentation. A biopsy was made of a verrucous lesion from the thigh at this time, and 2 months ago, when the entire process had mostly come to splashes of hyperpigmentation, another biopsy was performed on the chest.
