Abstract
BACKGROUND: Postoperative pyoderma gangrenosum (PG) is a neutrophilic dermatosis characterized by the development of PG-type lesions within surgical sites. OBJECTIVE: We sought to characterize postoperative PG as a distinct subtype of PG for earlier recognition and prevention of improper therapy. METHODS: We conducted a retrospective chart review of patients with nonperistomal postoperative PG at Mayo Clinic from 1994 to 2014.x RESULTS: Eighteen patients had postoperative PG with an average age of 58 years. Fifteen (83%) were female. Among patients with postoperative PG, 4 (22%) had an associated systemic disease traditionally associated with PG. Sites of postoperative PG included 7 breast (38%), 7 abdomen (38%), 1 back, 1 shoulder, 1 ankle, and 1 scrotum, witxxh breast reconstruction being the most common surgery. The average time to symptoms was 11 days. No patients had a fever. Eight (44%) had documented anemia and 5 (27%) had leukocytosis. Antibiotics and systemic corticosteroids were initiated in 10 (56%) and 14 (83%), respectively. Debridement was done in 11 (61%) patients. LIMITATIONS: Small sample size and retrospective study are limitations. CONCLUSION: Postoperative PG is a rare surgical complication with predilection for the breast and abdomen of females and has less association with systemic disease than idiopathic PG. Early recognition may prevent unnecessary debridements and morbidity.
