The prevalence of birthmarks and cutaneous skin lesions in newborns vary among sex and race. There are limited reports of birthmarks and cutaneous lesions among Thai neonates.
To determine the prevalence of birthmarks and cutaneous lesions in Thai newborns and evaluate the association between age, gender maturity, route of delivery, birth weight and skin lesions.
All of the subjects were healthy newborn infants, who were born between September 2008 to September 2009. They were enrolled and examined for cutaneous lesions by two dermatologists.
574 neonates were included in this report. The most common pigmentary birthmarks were Mongolian spots (100%), followed by congenital melanocytic nevi (2.4%) and Cafe-au-lait spots (0.3%). The most common vascular birthmarks were salmon patch (16.6%), hemangiomas (0.30%) and vascular malformations (0.3%). Among the cutaneous lesions; the three most common skin lesions were sebaceous gland hyperplasia (78%), Epstein's pearls (71.3%), and erythema toxicum neonatorum (46.5%).
Mongolian spot was the most frequent birthmark while sebaceous gland hyperplasia was the most frequent cutaneous lesions found among Thai neonates. The prevalence of the cutaneous lesions of newborns differ among countries could possibly be due to race, the age of the infants and the period of observation of the study subjects.
新生儿胎记和皮肤病变的患病率在性别和种族之间存在差异。关于泰国新生儿胎记和皮肤病变的报告有限。
确定泰国新生儿胎记和皮肤病变的患病率，并评估年龄、性别成熟度、分娩方式、出生体重与皮肤病变之间的关联。
所有受试者均为健康新生儿，于2008年9月至2009年9月出生。他们由两名皮肤科医生登记并检查皮肤病变。
本报告纳入了574名新生儿。最常见的色素性胎记是蒙古斑（100%），其次是先天性黑素细胞痣（2.4%）和咖啡斑（0.3%）。最常见的血管性胎记是鲑鱼斑（16.6%）、血管瘤（0.30%）和血管畸形（0.3%）。在皮肤病变中，最常见的三种皮肤病变是皮脂腺增生（78%）、 Epstein珍珠疹（71.3%）和新生儿毒性红斑（46.5%）。
蒙古斑是泰国新生儿中最常见的胎记，而皮脂腺增生是最常见的皮肤病变。不同国家新生儿皮肤病变的患病率可能因种族、婴儿年龄和研究对象的观察期而异。
