Statistical survey of skin changes in Japanese neonates.
We observed 5387 infants over 10 years in weekly visits to a neonatal ward and obtained the following frequency data on these skin changes: erythema toxicum neonatorum, 40.8%; perianal dermatitis, 18.9%; scrotal pigmentation, 15.2%; miliaria, 8.5%; and adnexal polyp of neonatal skin, 4.1%. The frequencies of the types of birthmarks were: mongolian spots, 81.5%; salmon patches, 22.3%; nevocellular nevi, 2.7%; port-wine stains, 2.1%; strawberry marks, 1.7%; café au lait spots, 1.7% (including a case of von Recklinghausen's disease); epidermal and sebaceous nevi, 0.3%; accessory auricles, 0.3%; and smooth muscle hamartomas, 0.2%. A positive relationship was observed between infant maturity and the prevalence of erythema toxicum neonatorum. Apart from candidiasis, neonatal skin infections were extremely rare.
