arteriolar nephrosclerosis

A destructive form of atherosclerosis involving the renal arteries secondary to severe–malignant (renovascular) hypertension which, if prolonged, leads to renal failure.
Histologic patterns
• Hyaline arteriolosclerosis, in which there is homogeneous pink hyaline thickening of the arteriolar walls, is associated with benign nephrosclerosis.
• Fibrinoid necrosis of arterioles accompanied by an inflammatory infiltrate resulting in necrotising alveolitis and hyperplastic arteriolitis, with onionskin-like layering of fibroblasts, smooth muscle cells, and collagen.
• Hyperplastic arteriolosclerosis, with a concentric thickening with progressive narrowing of the lumina, may be associated with malignant hypertension, nephrosclerosis, and scleroderma.

1988) suggested that diets high in fat lead to arterionephrosclerosis, which in combination with cholesterol deposits in the renal tubules may enhance the development of renal cancer.
Arterionephrosclerosis (also called hypertensive nephropathy/nephrosclerosis) is the most common finding in adult tumor nephrectomy specimens.
The pathologic diagnosis of arterionephrosclerosis is based on a constellation of nonspecific histopathologic features.
