The condition typically manifests clinically as a pustule or plaque that quickly evolves into a necrotic ulcer with undermined violet-colored margins. A surgical debridement might worsen the disease due to the pathergy phenomenon. This case report presents a 48-year-old woman who underwent a late breast reconstruction with a transverse rectus abdominis myocutaneous flap and was subsequently diagnosed with PG.
