Trophic lesions of the lower limbs are very frequent in diabetic patients, especially after long periods of poor glycemic control. These lesions are caused by some diabetic sequelae, namely neuropathy and angiopathy. The human and social cost of trophic lesions is very high; for this reason education of diabetics who are likely to develop such lesions is extremely important. When trophic lesions have developed, conservative management is based on local and general therapy. Amputation is taken into account only when conservative management has failed.
