The typical triad of clinical symptoms include unilateral painless cervical adenopathy or subcutaneous masses largely in the head and neck region, characteristic histologic features, as well as peripheral eosinophilia, and elevated serum IgE levels.[5] Histologically, KD is identified by follicular hyperplasia with active germinal centers along with a proliferation of arteriolar and capillary vasculature encompassed by concentric rings of reactive fibrosis composed of hyaline and collagen. Here, IGHE is linked to Increased total eosinophil count.
