Orange–brown chromonychia, a novel finding in Kawasaki disease
- 234 Downloads
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.
