Kawasaki disease (KD) is one of the commonest vasculitis of childhood, where diagnosis is clinical based on a plethora of signs and symptoms. One of the typical findings is the changes in the extremities including the nail changes. Orange-brown chromonychia is a colour change in the nails which has been observed in some cases of KD. Here, we report a series of 40 patients of KD, where a typical transverse orange-brown discolouration of nails or chromonychia was noted in 29 patients. Though chromonychia is noted in many other rheumatic and nonrheumatic diseases, the typical transverse orange-brown chromonychia observed in KD patients can be included as an additional clinical feature in diagnosis of KD.
川崎病（KD）是儿童最常见的血管炎之一，其诊断基于大量的体征和症状。其中一个典型的发现是四肢的变化，包括指甲的变化。橙色-棕色甲变色是 KD 病例中观察到的指甲颜色变化。在这里，我们报告了一系列 40 例 KD 患者，其中 29 例患者出现典型的横向橙色-棕色指甲变色或甲变色。虽然甲变色在许多其他风湿性和非风湿性疾病中都有发现，但在 KD 患者中观察到的典型横向橙色-棕色甲变色可以作为 KD 诊断的附加临床特征之一。
