Acute exacerbation of chronic osteomyelitis triggered by aggravation of type 2 diabetes mellitus: a case report.

Here we report a case of chronic osteomyelitis under poorly controlled diabetic conditions. Interestingly, chronic osteomyelitis was observed at the same position where acute osteomyelitis was observed in his babyhood. In addition, chronic osteomyelitis was repeatedly observed, and it seemed that its acute exacerbation was closely associated with aggravation of type 2 diabetes mellitus. We should bear in mind that type 2 diabetes mellitus is one of the major risk factors of osteomyelitis and that acute exacerbation of chronic osteomyelitis could be triggered by a disturbance of glycemic control in patients with type 2 diabetes mellitus.
