Fournier's gangrene

Fournier's gangrene was traditionally thought to arise spontaneously. More recently, cases with urological, perianal or systemic predisposing causes have been reported. This report describes four cases of Fournier's gangrene, all associated with a predisposing cause: two with diabetes mellitus, two secondary to urinary tract pathologies, and one secondary to an infected wound after an inguinal herniorrhaphy.
