[Diabetic skin changes from the dermatological point of view].

Even a half of diabetic patients are suffering from skin troubles. Hyperglykemia causes skin changes leading to higher incidence of bacterial and mycotic infections, provokes skin degenerative processes, macro- and microangiopathy and neuropathy. Diabetic dermopathy, rubeosis, bullousis and scleredema are based on these changes. Other skin diseases including necrobiosis lipoidica, granuloma anulare, vitiligo, perforating folliculitis accompany diabetes frequently but their etiopathogenesis is not clear.
