Bacterial endocarditis and lymphadenopathy mimicking Kawasaki disease.

Two children whose illness initially fulfilled the clinical criteria for the diagnosis of Kawasaki disease were both subsequently found to have acute bacterial endocarditis and one child had a disseminated non-Hodgkins lymphoma. We describe their clinical course and emphasize the importance of the exclusion of other diagnosis as well as strict adherence to the accepted diagnostic criteria of Kawasaki disease.
