Unusual manifestations in children with Kawasaki disease

Between January 1983 and December 1992, the medical records of 187 patients (116 boys and 71 girls) with Kawasaki disease (KD) who were admitted to the hospital in the acute phase were retrospectively reviewed. Of these, 175 patients (93.6%) were under 4 years of age. Among the six principal symptoms of KD, the incidence of cervical lymphadenopathy (41.2%) was relatively low. Additionally, we found some unusua featuers including intussusception in a 1-month-old female, transient thrombocytopenia in seven children (3.7) and associated features make KD puzzling and difficult to diagnose. In caring for children with KD, physicians should be alert to the principal symptoms as well as the unusual associated manifestations.
