Fournier gangrene

Friday 29 April 2022


Definition : Fournier gangrene is a type of necrotizing cellulitis or gangrene affecting the external genitalia or perineum. It commonly occurs in older men, but it can also occur in women and children. It is more likely to occur in diabetics, alcoholics, or those who are immunocompromised.


Most cases of Fournier gangrene are infected with both aerobic and anaerobic bacteria such as Clostridium perfringens. It can also result from infections caused by group A streptococcus (GAS), as well as other pathogens such as Staphylococcus aureus and Vibrio vulnificus.

Lack of access to sanitation, medical care, and psychosocial resources has been linked to increased mortality.

It has been reported that blood sugar levels were elevated in 46 percent of patients diagnosed with Fourniers. Another study reported that about one third of patients were alcoholic, diabetic, and malnourished, while another ten percent had been immunosuppressed through chemotherapy, steroids, or malignancy.

Fournier gangrene is a rare side effect of SGLT2 inhibitors (canagliflozin, dapagliflozin, and empagliflozin), which increase the excretion of glucose in the urine.
