A 32-year-old woman with type 2 diabetes mellitus suffering from morbid obesity 
with BMI 45,14 kg/m(2) was operated on. Not only the type 2DM but also one of 
its complication known as necrobiosis lipoidica diabeticorum remitted 
postoperatively. Obesity should no longer be regarded simply as a cosmetic 
problem affecting certain individuals but an epidemic that threatens global 
well-being. It causes or exacerbates many health problems, and in particular, it 
is associated with the type 2 diabetes. Necrobiosis lipoidica is a granulomatous 
skin disease of unknown etiology, associated mainly with diabetes mellitus. We 
presented in this paper a morbid obese case of necrobiosis lipoidica 
diabeticorum with dramatic good response to bariatric surgery.
