[Present views on Kawasaki's syndrome (author's transl)].

Recent findings seem to confirm that the pathophysiological mechanism responsible for Kawasaki's syndrome is of immunological origin. Cardiac involvement (coronary aneurysm/thrombosis) is not uncommon, and its influence on prognosis remains a cause for concern. Improved diagnostic (ultrasonography) and therapeutic approaches, together with prolonged surveillance of the patients, appear to have reduced the death rate.
