Postsurgical pyoderma gangrenosum and flap necrosis in a head and neck cancer patient following neck dissection

Abstract

Postsurgical pyoderma gangrenosum (PSPG) develops in the skin after surgery without known cause. Immunosuppression constitutes first-line therapy and increases the likelihood of successful surgery when needed. PSPG should be considered when a flap necrosis occurs.
