Fournier gangrene is a type of necrotizing fasciitis that affects the perineum, including the genitalia and perianal region. It is a life-threatening condition characterized by the rapid spread of infection and tissue death.

Causes

Fournier gangrene is caused by a polymicrobial infection, which means it involves multiple types of bacteria. Common bacteria involved include Escherichia coli, Klebsiella, and Staphylococcus aureus. The infection often starts in the urogenital tract, perianal region, or skin and spreads rapidly.

Risk Factors

Several factors increase the risk of developing Fournier gangrene, including:

• Diabetes mellitus
• Alcoholism
• Immunosuppression (e.g., due to HIV/AIDS or chemotherapy)
• Obesity
• Chronic kidney disease

Symptoms

Symptoms of Fournier gangrene include:

• Severe pain in the genital area
• Swelling and redness
• Fever and malaise
• Foul-smelling discharge
• Crepitus (a crackling sensation under the skin)

Diagnosis

Diagnosis is primarily clinical, based on the symptoms and physical examination. Imaging studies such as CT scan or MRI can help assess the extent of the infection.

Treatment

Treatment involves:

• Surgical debridement to remove dead tissue
• Broad-spectrum antibiotics to treat the infection
• Supportive care including fluid resuscitation and pain management

Prognosis

The prognosis of Fournier gangrene depends on the severity of the infection and the timeliness of treatment. Early intervention improves outcomes, but the condition can be fatal if not treated promptly.
