Histopathologic features of KD. A, Low-power examination shows a striking nodular lymphocytic infiltrate involving the reticular dermis and subcutaneous fat. No significant fibrosis was noted. B, Higher-power magnification shows the basic composition of this infiltrative process being one of reactive germinal centers surrounded by small mature lymphocytes and eosinophils accompanied by numerous small-caliber vessels defining a form of angiomatous pseudolymphoma. (A and B, Hematoxylin-eosin stain; original magnifications: A, ×20; B, ×400.)
