A case fulfilling the criteria for the diagnosis of diabetic amyotroph
y is reported. Based on the clinical and electrodiagnostic features, i
t is concluded that diabetic amyotrophy is a recognizable clinical ent
ity that can be differentiated from other diabetic neuropathies. The s
ite of the lesion and the pathogenesis in diabetic amyotrophy remain c
ontroversial. The course of the illness is variable with gradual, but
often incomplete, improvement. (C) 1996 American Association of Electr
