We report the case of a patient with a 20-year history of diabetes mellitus type 2 who developed sclerotic skin lesions on his neck and upper back. Physical and histological findings were compatible with diabetic scleredema. T2-weighted magnetic resonance imaging (MRI) revealed diffuse thickening of the dermis and subcutaneous tissue, with hyperintense signals. The MRI findings in the dermis corresponded with the accumulation of collagen tissue with deposition of glycosaminoglycans.
