Delayed recognition of an intersphincteric abscess as the underlying cause of Fournier's scrotal gangrene.

It has recently become increasingly clear that Fournier's gangrene, far from being 'idiopathic' as initially thought, often originates from preexisting perianal or periurethral sepsis. The aetiology is discussed and an example quoted where the associated intersphincteric abscess was not recognised until some 3 months after the initial presentation. It is recommended that all patients presenting with Fournier's gangrene be examined by an experienced rectal surgeon early in the course of their illness.
