Summary

The authors present in short the main metabolic and physiological perturbations wich favorise the aparition of multiple dematoses during the evolution of diabetes mellitus. The authors classified from an evolutive point of view those dermatoses in two groups: the first group dermatoses without a well established correlation with the age of diabetes (with the possibility to be developed at any time during the diseas”s evolution, even before) and the second group with a well established correlation in time with the diabetes, including dermatoses as more frequent as the diabetes is older.

That review article continues with description of the most important associations between diabetes and skin diseases. The first group includes necrobiosis lipoidica, granuloma annulare, acanthosis nigricans and Buschke”s scleredema, with a comprehensive clinical and histological description. The second group includes diabetic dermo-pathy, bulosis diabeticorum, diabetic hand, eruptive xan-thomas, Huntley”s papules of the fingers and with a more detailed description the diabetic foot.
