Correct Answer � C Explanation |
 |
Ans.C. Polyarteritis nodosa
This vascular lesion is seen in hyaline arteriosclerosis, not polyarteritis nodosa.
Hyaline arteriolosclerosis, the vascular lesion associated with hypertension is both more prevalent and more severe in diabetics than in nondiabetics. It may be seen in older nondiabetics without hypertension.
It takes the form of an amorphous, hyaline thickening of the wall of the arterioles, which causes narrowing of the lumen.
