Kawasaki Disease & Fingernail Ridges
Children and infants are sometimes diagnosed with Kawasaki disease. The exact cause of this disease is still unknown.. The disease itself causes body-wide inflammation of the blood vessels. Kawasaki disease may also affect the fingernails in some pediatric patients.
Nail changes that typically manifest in children with Kawasaki disease include orange and brown coloration under the fingernail and separation of the nail plate. Horizontal ridges called Beau's lines may also develop and may be related to inflammation.
