A Rare Case of Ischial Tubercle Pressure Sore with Secondary Periperineal Necrotizing Fasciitis

Perineal necrotizing fasciitis, or Fournier's gangrene, is a rare but rapidly progressing condition characterized by fascial necrosis. It is a severe, potentially life-threatening infection requiring prompt diagnosis and standardized treatment to optimize patient outcomes.

A 48-year-old woman with poorly controlled type 2 diabetes developed necrotizing fasciitis of the right perineum secondary to an ischial tuberosity pressure ulcer. She had a prior spinal cord injury resulting in sensory dysfunction in the lower limbs, which masked significant pain. Management included surgical debridement, open wound care, antimicrobial therapy, and a free skin graft for wound closure.

Effective treatment of necrotizing fasciitis relies on aggressive debridement and appropriate antimicrobial therapy. This case highlights the importance of early recognition and intervention to improve clinical diagnostic and management strategies.
