Novel Treatment of Pyoderma Gangrenosum With Porcine-Derived Extracellular Matrix Following Bilateral Latissimus Dorsi Breast Reconstruction: A Case Report.

Pyoderma gangrenosum (PG) is a rare disease characterized by ulcerative cutaneous lesions that can occur postoperatively and is often associated with autoimmune disorders. PG is diagnosed by excluding other conditions that can cause ulcerations, such as infections, which may also result in immunosuppressive treatment delays and suboptimal wound care. Operative debridement of wounds has traditionally been avoided in the acute setting secondary to pathergy. This article presents a case of extensive breast PG that was successfully treated with surgical debridement, porcine-derived extracellular matrix, and negative pressure wound therapy while on systemic immunosuppressive therapy.
