[Rare manifestations of diabetic neuropathy]

Up to 50% of diabetic patients develop neuropathies during their lives. Distal symmetric polyneuropathy is the most frequent variety, but there are other forms that are not exceptional and must be considered for the differential diagnosis of these patients. In this paper, the authors present three clinical cases of rare types of diabetic neuropathy: oculomotor cranial neuropathy (Case 1), diabetic amyotrophia (Case 2) and mixoide type with proximal asymmetrical locomotor neuropathy and distal polyneuropathy (Case 3). Their most relevant clinical characteristics are described, along with their differential diagnosis, evolution and therapeutical alternatives, in order to contribute to a better management of these patients.
