Pyoderma gangrenosum is a chronic neutrophilic dermatosis which can occur following trauma or surgery and can mimic infection. Surgical intervention can lead to progression of disease.
This case series describes 3 cases of post-surgical pyoderma gangrenosum with delayed diagnosis from two large medical centers.
Epidemiology, pathogenesis, clinical and histopathologic presentation, and management of post-surgical pyoderma gangrenosum are discussed with a review of the literature.
Post-surgical pyoderma gangrenosum (PSPG) can mimic ulcerative disorders including bacterial infection. The diagnosis should be suspected in post-operative wounds with negative bacterial cultures which progress despite broad-spectrum antibiotics and surgical debridement. Recognizing the clinical features of PSPG is fundamental to prevent severe destruction and deformity.
坏疽性脓皮病是一种慢性嗜中性皮病，可在创伤或手术后发生，且可能类似感染。手术干预可导致疾病进展。
本病例系列描述了来自两个大型医疗中心的3例术后坏疽性脓皮病延迟诊断病例。
结合文献综述，讨论了术后坏疽性脓皮病的流行病学、发病机制、临床和组织病理学表现以及治疗。
术后坏疽性脓皮病（PSPG）可类似包括细菌感染在内的溃疡性疾病。对于细菌培养阴性、尽管使用了广谱抗生素和手术清创仍进展的术后伤口，应怀疑该诊断。认识PSPG的临床特征对于预防严重破坏和畸形至关重要。
