Florid diabetic complications in impaired glucose tolerance.

We report a 56-year-old gentleman who had a history of impaired fasting glucose 4 years earlier but spontaneously reverted to normoglycemia. He subsequently presented with impaired glucose tolerance and proteinuria. Detailed evaluation revealed florid complications of diabetes, including nodular glomerulosclerosis of the kidney. Such complications in pre-diabetes have rarely been reported. We need to search for them early to prevent further morbidity.
