title: Pigmented skin lesions in black newborn infants.
abstract: Three findings from a study of one hundred black newborn infants examined for pigmented lesions are presented herein: significantly higher incidence than in prior neonatal examinations, a frequent clinical pattern of grouped macules, and an unusual histologic distribution of nevus cell theques. Fifty-one percent of the infants had congenital pigmented lesions. Biopsy specimens of thirty-two lesions were obtained, twenty-six showing histologic changes of lentigo, four melanocytic nevi (nevus-cell nevi), and two ephelides. Three of the four nevi were less than 1.5 cm in diameter and all were of the predominantly junctional type. Clinical appearance was not a consistent guide for classification in the newborn.
