A Case of Fournier's Gangrene: A Rare, Lethal Skin Infection

Fournier's gangrene (FG) is a rare form of necrotizing fasciitis that is characterized by fascial necrosis of the genitalia or perineum. FG typically results as a complication of genital or anorectal abscess, pressure sore, or surgical site infections. Many patients present with no symptoms, whereas other patients may present with non-specific symptoms such as pain or erythema in the genital or perianal regions. We present a case of FG in a 76-year-old male. Our patient presented initially with only complaints of perianal and groin pain. Upon imaging and skin examination, a diagnosis of Fournier's gangrene was made. However, due to the late recognition and treatment of FG, the patient developed a sequence of fatal complications that ultimately resulted in his passing. This case demonstrates the importance of a rapid diagnosis of this rare disease to prevent fatal complications. We hope to inform dermatologists, internists, and urologists of the varying presentations of Fournier's gangrene to allow for prompt initiation of treatment.
