[Cutaneous lesions during the 1st week of life in 306 consecutive newborn infants].

The authors report the results of a systematic study of the skin conducted during three months in 306 neonates born in a hospital maternity unit in the Hauts-de-Seine departement, France. Two hundred and ninety-nine infants could be examined: 91 (30.5 p. 100) developed erythema toxicum neonatorum; 102 (34 p. 100) had port wine naevus; 42 (14 p. 100) mongolian spot, and 10 (3.5 p. 100) pigmented epidermal naevus. Various other abnormalities were found. These findings are compared with those of previous French (5, 14) and foreign (1, 3, 7-11, 13, 16, 17-19) studies.
