Three histopathological types of KD have been reported: proliferative, necrotizing, and xanthomatous. In a study, done at Israel the most common histological type was necrotizing type 63%, followed by xanthamous and proliferative type 21% and 16% respectively.7 The proliferative phenotype is composed of various histiocytes, plasmacytoid monocytes, and lymphoid cells with kariorrhectic nuclear fragments and eosinophilic apoptotic debris in the absence of neutrophils.
