Commonest histological finding in benign hypeension is

Hyaline aeriolosclerosis is associated with benign hypeension. It is marked by homogeneous, pink hyaline thickening of the aeriolar walls, with loss of underlying structural detail, and luminal narrowing . The lesions stem from leakage of plasma components across injured endothelial cells, into vessel walls and increased ECM production by smooth muscle cells in response to chronic hemodynamic stress.
