Type 1 diabetes with no diabetic complications, 62 years later.

We report a type 1 diabetes in an 88-year-old female patient discovered in 1938 at the age of 26. She was promptly put on insulin, which lasted 62 years so far. This patient was highly remarkable because she portrayed a historical case of insulin-treated diabetes diagnosed in 1938. The absence of microangiopathy and specially retinopathy was quite singular, all the more reason that her diabetes was ill-controlled. Environmental or genetic factors may, one day, explain this unusual favourable outcome.
