title: Diabetes mellitus and Fournier's gangrene.
abstract: A case is described in which Fournier's gangrene was the presenting feature of diabetes mellitus and in which extensive subcutaneous emphysema prevented the use of spinal anaesthesia for debridement. In the literature four cases have been reported in which Fournier's gangrene was the presenting feature in patients with diabetic ketoacidosis. Diabetes may predispose to a form of Fournier's gangrene in which subcutaneous gas formation is marked, though subcutaneous emphysema to the degree described in this case has not previously been reported in this condition. Diabetes mellitus and subcutaneous emphysema must be sought in patients with Fournier's gangrene as both may have a profound influence on management.
