Congenital pigmented and vascular lesions in newborn infants

Abstract

The incidence of congenital cutaneous lesions was ascertained by a single dermatologist in each of 830 sequential newborn infants over a 3-month period at the Oklahoma Teaching Hospitals. Lesions were observed in 57% of infants (77% of blacks and 49% of nonblacks). Vascular lesions were the most frequent, occurring in 44% of neonates. Pigmented lesions other than mongolian spots were observed in 15.8% of blacks and in 1.6% of whites. Clinical criteria do not readily distinguish nevus cell nevi from other pigmented lesions. Wood's light examination did not enhance the identification of congenital lesions. Inadequate examination of infants and marked underreporting of congenital lesions in newborn infants are widespread.
