[Insulin resistant diabetes, acanthosis nigricans and Bartter's syndrome, a fortuitous association?]. / Diabète insulinorésistant, acanthosis nigricans et syndrome de Bartter, une association fortuite?

The authors have followed during 10 years a girl with Bartter's syndrome who developed severe insulin resistance with acanthosis nigricans. In this rare association, hypokalemia and renal failure did not appear to be relevant factors triggering the onset of diabetes. The therapeutic difficulties in this case have still not been resolved.
