Pigmentary problems are one of the most frequent causes of dermatologic consultation in the tropics. This article deals with diseases seen mostly in tropical countries (ashy dermatosis, lichen planus pigmentosus, frictional dermatitis, pityriasis versicolor, and pinta) and in which a combination of racial, ecologic, nutritional, and social factors all contribute. Other common dermatoses seen worldwide, such as vitiligo and melasma, sometimes acquire dramatic expressions in tropical countries, and their management is usually difficult even for the most experienced dermatologists.
色素沉着问题是热带地区皮肤科门诊最常见的病因之一。本文探讨主要见于热带国家的疾病（灰白色皮肤病、色素性扁平苔藓、摩擦性皮炎、花斑癣和品他病），这些疾病是种族、生态、营养和社会因素共同作用的结果。其他在全球范围内常见的皮肤病，如白癜风和黄褐斑，在热带国家有时会有显著表现，即使对最有经验的皮肤科医生来说，其治疗通常也很困难。
