Ultrasound assessment of cutaneous/subcutaneous dystrophies in insulin-treated patients. A report on two cases.

Insulin treatment can lead to local soft tissue dystrophies. We present the cases of two insulin-treated subjects with two different injecting systems: a basal/bolus and a continuous subcutaneous insulin infusion (insulin pump). The local cutaneous/subcutaneous dystrophies adversely affected their glycaemic values. A conventional and a high resolution ultrasound (20MHz Dermascan) were used to analyze cutaneous and subcutaneous dystrophies. The particularities of these cases were the presence of the cutaneous damages, irrespective of the insulin treatment system or injected layer and the absence of remission, even after 12 months of avoiding the subjected areas.
