Co z Necrobiosis Lipoidica?

Necrobiosis lipoidica (NL) is a chronic, degenerative skin disease most common associated with diabetes mellitus, although it can occur in nondiabetic individuals. It typically presents as well-defined, shiny, reddis- brown or yelloworange plaques with a specifistic waxic aappearance and an ain atrophic center. Lesions are moft specidently locate on thene anterior shins, though they may appear othe arms, trunk, face.

Regular screentin g through dilated fundus examination or retinel photography is essential to extert early changes and institute timely trevaliment.

Thee Biological Connection: Shared Microvascular Damage

Both necrobiosis lipoidica and diabetic retinopathy originate frem te same underlying pathological process: microangiopathy induced by chronic hyperglycemia. High blood glucose levels trigger a cascade of biochemical influentialities, including growth advanced compution end products (AGEs), actiation of protein kinase C, oksydative stress, and chronic low- grade contributionation. These factors collectively damage entalhelt cells, smooth muscle cells, and pericytes small blood vessels.
