Vascular  pathology  in Hypertension
Hypertension is associated with two forms of small blood vessels disease -
1. Hyaline arteriolosclerosis

There is homogenous, pink, hyaline thickening of arteriolar wall.
The lumen becomes narrow.
It is characteristic of benign hypertension.
It may also occur in diabetes and aging.

2. Hyperplastic arteriosclerosis

It is characteristic of malignant hypertension.
There is concentrentic, laminated thickening of arteriolar wall → onion skinning.
There is mutinous intimal thickening and fibrous intimal thickening.
There may be accompanied fibrinoid deposits with necrosis of the vessels wall → fibrinoid necrosis.
