Pathologic findings in patients with Kawasaki Disease.

RCIA=right common iliac artery, SA/C=subacute/chronic inflammation, CA=coronary artery, CAA=coronary artery aneurysm, LMP=luminal myofibroblastic proliferation, MI=myocardial infarction, TX=transplant, Mac=macrophage, SI=small intestine, RCA=right coronary artery, LAD=left anterior descending artery, LCx=left circumflex artery, IMA=inferior mesenteric artery, GB=gallbladder, MV=mitral valve, TV=tricuspid valve, PV=pulmonary valve, GT=granulation tissue, eos=eosinophils, SMA=superior mesenteric artery, PA=pulmonary arteries, macs=macrophages, PMNL=predominantly neutrophils, U=unknown, N/A=not available, EFE=endocardial fibroelastosis, ECMO=extracorporeal membrane oxygenation, IVC=inferior vena cava. Notes: CA sections usually contained myocardium, epicardium, and some endocardium. All patients had active SA/C plus LMP in coronary and also in available non-coronary arteries. Varying degrees of chronic hypoxia (hydropic change) seen in all cases. Anitschkow cells always seen, if case had at least two sections of myocardium. EFE always seen, if specimens included more than focal endocardium. By report=slides not available, but description sufficient to derive pathology.
