Abstract
- Pyoderma gangrenosum (PG) is an uncommon ulcerating inflammatory neutrophilic dermatosis. Multifactorial pathogenesis has been reported because the underlying mechanism needs to be clearly elucidated. A pathergic reaction is a pathogenic aggravating factor of PG. The occurrence of postoperative PG (PPG) within and involving the borders of a surgical incision site suggests the role of a pathergic reaction in PG. Massive debridement should be avoided in PPG, and it should be immediately managed with oral prednisolone. We present 2 cases of PPG with different clinical courses according to the primary management.
