ABSTRACT
Several physiological skin changes such as vernix caseosa, cutis marmorata, physiologic desquamation, and sebaceous hyperplasia have been described in the neonatal period. There are also clinical characteristics of skin peculiar to neonate and infancy. Skin disorders observed during neonatal and infancy period can be divided into transient skin lesions, birth marks, and other diseases. Transient skin lesions include milia, sebaceous gland hyperplasia, erythema neonatorum, transient neonatal pustular melanosis, and acne neonatorum. Nevocellular nevus, mongolian spot, vascular malformation, hemangioma, epidermal nevus, and sebaceous nevus belong to birth marks. There are several common skin diseases such as miliaria, diaper dermatitis, atopic dermatitis, seborrheic dermatitis, and cutaneous candidiasis.

BACKGROUND: The skin shows many physiological changes during pregnancy. Although these physiological skin changes do not usually impair the health of the mother or the fetus, some can be cosmetically significant and of importance to the dermatologist. OBJECTIVE: The aim of our study was to determine the incidence and clinical findings of these skin changes during pregnancy. METHODS: We made a prospective study of 157 women in the third trimester of pregnancy who visited the prenatal care clinic at Seoul National University Hospital from January 1996 to June 1996. Women with pathological pregnaneies were excluded. RESULTS: The results of the study are summarized as follows. 1. Various skin changes occurred such as pigmentary alteration, vascular changes, striae, abnormalities in hair growth, and nail changes. In all subjects, one or more of these changes were found. 2. The incidence of hyperpigmentation was highest among the skin changes. The incidence of hyperpigmentation of areola and nipple was 100%. Linea nigra were observed in 81.5%. 3. Palmar erythema, suprapubic hirsutism, and abdominal striae were observed in 36.3%, 14.0%, and 40.1 %, respectively. CONCLUSION: Physiological skin changes during pregnancy were various and observed with high frequency. The incidences of vascular changes, hair and nail changes in Korean pregnant women were reported for the first time.
