1、什么是白癜风
以下关于白癜风（有时也被称为癜）的定义和描述是来自白癜风协会网站，这是我找到的最准确，最简洁的定义和描述。
“白癜风是一个相当常见的皮肤病，每一百个至少有一人患有此病。在国家在世界各地，包括英国，任何肤色或人种，不论男女，都有病例。
白癜风导致皮肤或者毛发出现白色的斑块。这是因为给予皮肤颜色的黑素细胞已损坏或破坏。该疾病可以扩散，迅速或缓慢，最坏的可能是覆盖整个身体表面。
白癜风的最常见的形式为对称的形式，白癜风影响身体的两侧。在某些情况下，仅有单侧身体的受影响（节段性白癜风），这种类型的具有有限的进展，并且更难以治疗。
白癜风可开始于任何年龄，约50％的患者出现在20岁以前。
白癜风不会传染的。即使不会发生身体症状，但如果他们受到阳光直射白斑可能会晒伤。病情可能会导致严重的心理困扰，尤其是当面部，颈部，双手及阴部受到影响。虽然这种疾病使黑色或晒黑的皮肤更明显，困扰的程度并不一定与皮肤颜色或与疾病的严重程度有必然的联系。然而，皮肤黝黑的某些族群的白癜风患者可能会觉得更加痛苦。
白癜风的发展是不发预测的。有些人可能发病已经多年也不会注意到自己的病情，而有些他人却发展相当迅速。尽管白癜风是不能完全治愈的罕见的疾病，在某些情况下，特别是在儿童，白斑可自愈。

What Is vitiligo?
The following definition and description of vitiligo (or leucoderma, as it is sometimes called) is taken from the Vitiligo Society website and is the most accurate and concise I have found.
"Vitiligo is quite a common skin disease which affects at least one person in every hundred in countries throughout the world including the UK. Anyone, male or female, irrespective of skin colour or ethnic origin can develop the condition.
Vitiligo causes the skin, and sometimes the hair, to turn white in patches. This is because melanocytes, the cells which give the skin its colour, have either been damaged or destroyed. The disease can spread, rapidly or slowly, to cover the entire body surface (universal vitiligo) but this is not inevitable. The most common form of vitiligo appears in symmetrical form (generalised vitiligo) affecting both sides of the body. In some cases only one half of the body is affected (segmental vitiligo) and this type has limited progression and is more difficult to treat. Vitiligo can begin at any age, though about fifty percent of people develop it before the age of twenty.
You cannot catch vitiligo. It is not infectious. Although there are no physical symptoms apart from sunburn in the white patches if they are not protected from the sun, it can cause severe psychological distress, especially when the face, neck, hands and genitals are affected. Although the disease is more noticeable on dark or tanned skin the degree of distress is not necessarily linked to skin colour or to the extent of the disease. However, people with dark skin from certain ethnic groups who develop vitiligo may feel particularly stigmatised and fear a loss of identity should the disease become widespread.
The course of vitiligo is unpredictable. Some people may not notice a change in their condition for many years, while for others it can spread quite rapidly. In some cases the white patches can spontaneously repigment, particularly in children, though it is rare for the disease to resolve completely without treatment."
