Background Kawasaki disease (KD) is an acute idiopathic vasculitis affecting the small and medium-sized arteries especially coronary artery (CA). it occurs in childhood mostly below five years of age. Objective This study aims to identify the most common clinical features among KD patients in King Abdulaziz Medical City in Jeddah, Saudi Arabia from 1/1/1982 to 31/12/2018. Methods A case series study was conducted in all KD patients that were admitted to the King Abdulaziz Medical City from 1/1/1982 to 31/12/2018 except those who were diagnosed in other hospitals or whose diagnosis has later changed. The identification of patient was done by using the International Classification of Diseases (ICD) coding for KD (ICD9 446.1). Our data consisted of the patient’s file number, age at presentation, gender, whether the patients received IVIG treatment or not, number of days of fever before starting IVIG treatment, response to IVIG treatment, season in which the symptoms started and clinical features based on body’s system. Result The study included 18 patients, 11 males showed that (55.6%) of patients met the criteria of typical KD and most of them were less than five years old. In addition, most patients were reported to have polymorphous rash, cough, irritability, vomiting, and a murmur. All patients who received intravenous immunoglobulin (IVIG) treatment which demonstrated an improvement even though those who started the treatment after 10 days of fever. Conclusion In typical KD patients, the distribution of the clinical features was almost identical. However, there were some variations in them among atypical KD patients. Moreover, Evan though KD in our region is not common as in Japan, the incidence of giant aneurism was higher. In addition to that, this study and other study conducted in Saudi Arabia found that screened patients reported tachycardia more than patients in Japan. Recommendation As KD is still idiopathic, we recommend more details to be collected from the patients, especially consanguinity as it is common in Saudi Arabia
