Description
Summary:Urushidani and Oka discuss the case study of an 84-year-old man who was found to be hypotensive before receiving his regularly scheduled dialysis treatment and was referred to the emergency department. He reported slight fatigue but did not have any pain. The only potential source of infection that was identified was a small, black skin lesion near the anus, with induration and slight tenderness. Based on his clinical presentation, they diagnosed perineal fasciitis, also known as Fournier gangrene. They administered intravenous fluids and vasopressor support, and urgently consulted surgery. After stabilization, a computed tomography scan showed subcutaneous free air behind the rectum.
