Insulin-induced localized lipoatrophy.

Insulin lipoatrophy is a rare immunologic cutaneous complication in diabetes mellitus that presents with localized subcutaneous fat atrophy at the insulin injection site. We report the case of a 62-year-old woman with type 2 diabetes mellitus that developed localized lipoatrophy on the abdomen after 6 years of therapy with the insulin analogues detemir and aspart.
