title: Insulin-requiring diabetes mellitus of sixty years' duration without significant late manifestations.
abstract: The report concerns a man with onset of diabetes in 1921 and treated with insulin since 1922. In 1981, at the age of 75, he is in excellent health, with no signs of significant diabetic organ injuries. Among other factors, this benign course may be due to retention, until now, of some endogenous insulin production.
