Fournier’s Gangrene Induced by Rectal Cancer

Fournier's gangrene (FG) is a necrotizing fasciitis of the perianal, perineal, and genital regions, leading to necrosis of the fascia and subcutaneous tissue.It is a rare condition, particularly when induced by rectal cancer.Herein, we present a rare case in which FG was discovered incidentally during the physical examination of a patient who complained of general weakness.The patient was diagnosed with FG induced by rectal cancer with liver metastasis and underwent laparoscopic diverting loop ileostomy instead of abdominoperineal resection (APR).After 13 rounds of chemotherapy over 9 months, the condition of the rectal cancer partially improved.Furthermore, FG lesions showed improvement with this treatment plan compared to the initial treatment with dressings and antibiotics.Therefore prompt surgical intervention is important for treating FG induced by rectal cancer.
