Pyoderma Gangrenosum Following Deep Inferior Epigastric Perforator (DIEP) Breast Reconstruction: A Case Report

Abstract

Pyoderma gangrenosum (PG) is a rare dermatologic condition manifesting as sterile, rapidly progressing painful skin ulcerations. It is commonly associated with autoimmune disorders such as inflammatory bowel disease. This case report illustrates a severe case of post-surgical pyoderma gangrenosum (PSPG) following bilateral deep inferior epigastric perforator flap breast reconstruction in a 56-year-old Caucasian woman. Factors delaying diagnosis included negative personal/family history of inflammatory disorders and a clinical presentation more suggestive of breast cellulitis. Refractory antibiotic therapy, subsequent ulceration at multiple breast and abdominal incisions, and pathergic response to tissue biopsy supported an eventual clinical diagnosis of PSPG, 12 days postoperatively, despite equivocal histopathologic findings. Initiation of intravenous immunoglobulin, prednisone therapy, local wound care, and avoidance of debridement led to a full resolution by 5 months postoperatively. This study raises awareness for PSPG and highlights the importance of early recognition and urgent dermatology consultation to expedite optimal treatment and minimize subsequent fat necrosis.
