Necrotizing Dermatosis of the Arm Following Cubital Tunnel Release: Pyoderma Gangrenosum, the Great Mimic: A Case Report.

Case: We report the case of a fifty-one-year-old woman who underwent an uneventful cubital tunnel release and was admitted five days after surgery with a diagnosis of infection. Despite multiple surgical debridements and prolonged intravenous antibiotic treatment, the wound edges continued to slough and necrose. A delayed diagnosis of postsurgical pyoderma gangrenosum (PG) was made, and corticosteroid and immunosuppressive treatment was administered, with immediate clinical improvement.
