A 9-Year-Old Child with Kawasaki Disease Complicated with Mycoplasma Infection: A Case Report and Literature Review

Kawasaki disease (KD), also known as cutaneous mucosal lymph node syndrome, is an immune-mediated vasculitis, which is easy to involve small and medium-sized arteries, especially coronary arteries, and can cause a variety of cardiac sequelae. It primarily affects children from 6 months to 5 years old. In recent years, it has been reported that the incidence of KD is gradually increasing, and there are some reports of KD in teenagers and even adults. By reporting the clinical data of a 9-year-old KD child with mycoplasma infection who presented to children’s Hospital of Second Affiliated Hospital of Shaanxi University of Chinese Medicine and reviewing relevant literature, this paper aims to provide clinical reference for the prevention and treatment of missed diagnosis of KD in older children.
