Adult Kawasaki disease unrelated to epstein-barr virus and group A Streptococcus.

A 23-year-old Japanese woman with a fever and generalized skin eruptions was referred to our hospital in July 1999. At admission, her temperature was 38.9 degrees C, and she had fluctuating symptoms including erythema of the extremities, conjunctival hyperemia, strawberry tongue, and generalized skin eruptions, but lymphadenopathy was not verified. An initially elevated urine leukocyte count (more than 100 per high power field) later returned to normal range without antibiotic therapy. Adult Kawasaki disease was diagnosed on the basis of the above symptomology. Echocardiograph showed transient effusion in the pericardium. Using the Harada scoring system for treatment of Kawasaki disease, we gave the patient aspirin and did not administer intravenous immunoglobulin. The clinical course was uneventful, and on the day of discharge (day 22 after onset), the laboratory test results were nearly normal. Laboratory test results were negative for both Epstein-Barr virus and group A Streptococcus.
