”Diabetic shin spots/ Diabetic Dermopathy”

Diabetic dermopathy, also known as shin spots or pigmented pretibial patches, is a skin condition usually found on the lower legs of people with diabetes.

Diabetic dermopathy is a term used to describe the small, round, brown atrophic skin lesions that occur on the shins of the patients. The lesions are asymptomatic. It is thought to result from changes in the small blood vessels that supply the skin and from minor leakage of blood products from these vessels into the skin. Shiny round or oval lesions form on the thin skin of shins. The patches don’t hurt, and they rarely cause itching or burning.
