Skin Manifestations of Diabetes Mellitus

iabetes Mellitus (DM) refers to a group of metabolic disorders with a common presentation of hyperglycemia. There are two common types of DM. In Type 1, there is absolute or neartotal insulin deficiency; while in type 2, the problem originates from insulin resistance, impaired insulin secretion and raised glucose production (1). Skin disorders are common in diabetic patients and the prevalence up to 30% has been reported in these patients (2). Generally, these manifestations appear during the period of disease in known cases of DM, but they may also be the first presentation of the disease or appear many years before the diagnosis of DM (3). As expected, autoimmune skin disorders are more frequently observed in type 1 DM while infectious skin diseases are more prevalent in type 2 diabetic patients (4,5). Cutaneous manifestations of DM can be categorized into 5 groups: 1-Non-infectious skin disorders 2-Infectious skin disorders 3D 1Dermatologist, Assistant Professor, Yazd Diabetes Research Center, Shahid Sadoughi University of Medical Sciences, Yazd, Iran. 2MD, Yazd Diabetes Research Center, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.
