Vasculitis not commonly seen in adults
Correct Answer: Kawasaki disease
Description: Kawasaki's disease is an acute, febrile, multisystem disease of children. Some 80% of cases occur prior to the age of 5, with the peak incidence occurring at <=2 years. It is characterized by nonsuppurative cervical adenitis and changes in the skin and mucous membranes such as edema; congested conjunctivae; erythema of the oral cavity, lips, and palms; and desquamation of the skin of the fingeips. Although the disease is generally benign and self-limited, it is associated with coronary aery aneurysms in ~25% of cases, with an overall case fatality rate of 0.5-2.8%. These complications usually occur between the third and fouh weeks of illness during the convalescent stage. Vasculitis of the coronary aeries is seen in almost all the fatal cases that have been autopsied. There is typical intimal proliferation and infiltration of the vessel wall with mononuclear cells. Beadlike aneurysms and thromboses may be seenalong the aery. Other manifestations include pericarditis, myocarditis,myocardial ischemia and infarction, and cardiomegaly . Ref - Harrisons 20e p2588
