Fournier gangrene (necrotising fasciitis) – flesh-eating disease of the vulva

Fournier gangrene is a form of necrotising fasciitis (gangrene) that can affect the vulva and/or perineum in women. It most often occurs in men, however, with anyone suffering diabetes, alcoholism, kidney problems, steroid use or immune system deficiencies most at risk.​1,2​

A 2009 study stated that 39 out of 1,680 cases of Fournier gangrene were found in women, in particular older women between the ages of 50 and 100.

Some researchers believe that Fournier gangrene is a polymicrobial skin condition. This type of gangrene can occur after episiotomy or a Bartholin’s abscess.​3​

Symptoms of Fournier gangrene in women​4​

  • Swelling
  • Pain in the perineal or perianal area
  • Fever
  • Weakness
  • Foul odour
  • Pus
  • Skin turns black
  • Occurs quickly

Causes of Fournier gangrene Bacteria are the cause of Fournier gangrene, with both aerobic and anaerobic bacteria found guilty. In one study, the type of bacteria found included:

  • Escherichia coli
  • Klebsiella pneumoniae
  • Enterococcus
  • Morganella
  • Pseudomonas
  • Streptococcus
  • Staphylococcus
  • Proteus
  • Bacteroides spp.
  • Peptostreptococcus
  • Prevotella
  • Clostridium difficile

Treatment of Fournier gangrene

The typical treatment of Fournier gangrene is antibiotics intravenously, with surgical removal of dead tissue. Hyperbaric oxygen chambers have been used to increase oxygen in damaged tissue while also killing anaerobic bacteria.​5,6​
