[A case of acute spongiositis with diabetes mellitus].

We report a case of acute spongiositis with diabetes mellitus. A 63-year-old man with a 7-year history of diabetes mellitus was admitted to our hospital complaining of perineal pain and pyrexia. Physical examinations revealed induration and tenderness of the corpus spongiosum, but no signs of rubor or erosion. A laboratory investigation showed leukocytosis (12,000/microliter), an elevated level of C-reactive protein (3.38 mg/dl) and hyperglycemia (532 mg/dl). Pyuria and bacteriuria were absent. Magnetic resonance imaging (MRI) yielded abscess-like lesion of the corpus spongiosum. Culture of the aspirated specimen demonstrated B-hemolytic streptococci. Treatment with antibiotics and insulin resolved leukocytosis and tenderness of corpus spongiosum. He left the hospital on the 23rd day after admission and no evidence of recurrence of the spongiositis was found for 1 year after discharge.
