Typical histology in benign hypertension?
Intimal proliferation and hyalinization of media of medium arteries
Fibrinoid necrosis of small arteries
Loss of endothelial cells of arterioles
Formation of new vessels
Ans. (a) Intimal proliferation and hyalinization of media of medium arteries(Ref: Robbins 9th/pg 490; 8th/pg 495)There is increased myofibroblastic tissue in the intima along with hyaline deposits in benign hypertension. Intimal proliferation is usually the universal response of a vessel to injury.
