In polyarteritis nodosa, small aneurysms are strung like the beads of a rosary, [4] therefore making this "rosary sign" an important diagnostic feature of the vasculitis. [5] The 1990 ACR criteria were designed for classification purposes only, but their good discriminatory performances, indicated by the initial ACR analysis, suggested their ...
Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory disease of the blood vessels that causes abnormal growth within the wall of an artery. [1] FMD has been found in nearly every arterial bed in the body, although the most commonly affected are the renal and carotid arteries. [1] [2] [3]
Polyarteritis nodosa: Mononeuritis multiplex, nodules, purpura, livedo, and hypertension. [11] Kawasaki disease: Fever, conjunctivitis, exanthema, palmoplantar erythema, cervical lymphadenopathy, and mucosal enanthema.

Heart valve dysplasia (including mitral and tricuspid valve dysplasia) is a congenital heart abnormality in dogs. Dysplasia of the mitral and tricuspid valves - also known as the atrioventricular (AV) valves - can appear as thickened, shortened, or notched valves. Chordae tendineae are also usually abnormal.

"Onion-skin" renal arteriole. This is a type of arteriolosclerosis involving a narrowed lumen. [4] The term "onion-skin" is sometimes used to describe this form of blood vessel [14] with thickened concentric smooth muscle cell layer and thickened, duplicated basement membrane.
Arterial dysplasia is a term that refers to a group of conditions that affect the structure and function of the arteries. [1] One of the most common types of arterial dysplasia is fibromuscular dysplasia .
Fibrinoid necrosis is a pathological lesion that affects blood vessels, and is characterized by the occurrence of endothelial damage, followed by leakage of plasma proteins, including fibrinogen, from the vessel lumen; these proteins infiltrate and deposit within the vessel walls, where fibrin polymerization subsequently ensues.
