Abstract：
Vitiligo is an acquired chronic depigmenting disorder of the skin and is characterized by the destruction of melanocytes. One of the clinical features of vitiligo is that damage to normal skin frequently results in the formation of depigmented macules, which is known as Köebner\'s phenomenon (KP). Here, we presented a case of vitiligo, in which depigmented macules followed the course of a dilated varicose vein. Dilatation of blood vessels was considered to contribute to the development of the vitiliginous lesions as a trigger for KP. Any kind of skin injury can trigger KP, but this is only the second case in which a dilated blood vessel caused KP in vitiligo. J. Med. Invest. 71 : 177-178, February, 2024.

白癜风是一种获得性慢性皮肤色素脱失障碍，其特征在于黑素细胞的破坏。白癜风的临床特征之一是对正常皮肤的损害经常导致色素沉着斑的形成，这被称为柯伯纳现象(KP)。这里,我们介绍了一例白癜风,其中色素沉着的黄斑跟随静脉曲张扩张的过程。血管扩张被认为有助于白癜风病变的发展，这是KP的触发因素。任何类型的皮肤损伤都会引发KP,但这只是第二种血管扩张导致白癜风KP的情况。J.Med.投资。71:177-178,二月,2024.
