The Management of Postsurgical Pyoderma Gangrenosum following Breast Surgery.

Abstract

Background:Postsurgical pyoderma gangrenosum is a rare condition characterized by ulcerative lesion development at surgical sites. It is frequently misdiagnosed as infection and mismanaged with surgical debridement, which only worsens the condition. Achieving the correct diagnosis is crucial to delivering the appropriate medical therapy. This article presents four clinical cases of postsurgical pyoderma gangrenosum in breast surgery patients, and proposes a work-up schematic to aid in its diagnosis based on literature review and author experience.Methods:Four patients who developed postsurgical pyoderma gangrenosum following breast surgery were identified by chart review at our institution.Results:The cases include two breast reduction patients, an abdominally based breast reconstruction patient, and a breast augmentation patient. The time to diagnosis and treatment varied greatly between the patients, with diagnosis achieved as early as 13 days postoperatively to as late as one year postoperatively. Two of the four patients were initially mismanaged with surgical debridement, and all patients were treated with at least one course of antibiotics for a misdiagnosis of surgical site infection before they were correctly diagnosed.Conclusions:Postsurgical pyoderma gangrenosum is a rare, ulcerative condition that is difficult to diagnose and often mismanaged with surgical debridement. Diagnosis requires a high clinical suspicion and should be considered in patients with ulcerative lesions resistant to antibiotic therapy, in patients who have bilateral lesions with NAC sparring, and in those with systemic inflammatory conditions. Diagnosis is usually delayed, so it is imperative that surgeons keep this diagnosis in mind when treating breast patients with postsurgical wounds.
