Synopsis

Diabetic dermopathy, commonly known as shin spots, is found in up to 50% of diabetics and is the most common cutaneous finding in patients with diabetes mellitus. The etiology of diabetic dermopathy is unclear. Previously, ischemia had been thought to be a causative factor, but studies found that blood flow to the skin was actually increased as compared to other surrounding areas. Trauma is also thought to be a causative factor. There is no clear variation of incidence between diabetic dermopathy in patients with noninsulin-dependant diabetes mellitus versus those with insulin-dependant diabetes mellitus.

There is, however, a correlation between the presence of skin lesions and the number of microangiopathic complications (retinal, neuropathic, and/or nephrogenic) present. As the number of complications present increases from 1 to 3, so does the number of lesions. Thus, the incidence of diabetic dermopathy in patients with all 3 complications is much higher than in patients with just 1 complication.

The incidence of diabetic dermopathy increases with age. It is typically seen in patients aged older than 50. Men show an increased incidence compared to women. Although located bilaterally, their distribution is asymmetric. Lesions do not itch or cause pain. Control of blood sugar levels does not affect the outcome of the lesions. There is no correlation between diabetic dermopathy and obesity or hypertension.
