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