title: Orange-brown chromonychia, a novel finding in Kawasaki disease.
abstract: 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.
