Where this comes from

Abstract

Among the 365 children diagnosed as having Kawasaki disease (KD), only 5 children (1.4%) presented with splenomegaly: 2 complicated by macrophage activation syndrome and 3 ultimately received a diagnosis of alternative systemic illness. Splenomegaly is atypical in KD and a potential marker of an underling complication, namely macrophage activation syndrome, or diagnosis other than KD.
