Abstract
Postsurgical pyoderma gangrenosum (PSPG) is a rare, ulcerative skin condition that presents a diagnostic challenge due to its similar presentation to infectious etiologies in the postsurgical period—often leading to gratuitous and unnecessary surgery and antibiotic use. We report a 37-year-old female with breast cancer who received neoadjuvant chemotherapy and immunotherapy and underwent bilateral skin-sparing mastectomies who developed delayed bilateral mastectomy skin flap necrosis secondary to PSPG. This case had rare factors associated with the development of PSPG such as preoperative systemic therapy and a familial component. This case underscores the importance of early recognition of this rare disease and appropriate management of PSPG to prevent unnecessary interventions and ensure an optimal outcome.
