BACKGROUND Pyoderma gangrenosum is a rare ulcerating skin disease of unknown etiology, making its coincidence with orthopedic trauma a rare challenge. Patients are at risk of progression of the existing lesions and development of new lesions upon skin injury when surgical procedures are performed. To our knowledge, this is the first report in the literature of disease unrelated surgery during active pyoderma gangrenosum. CASE PRESENTATION We present a case of femoral neck fracture in a Caucasian patient with concurrent pyoderma gangrenosum localized in the axilla. Hemiarthroplasty was safely performed after disease activity was reduced with systemic corticosteroids. Tissue-protective wound closure was used together with perioperative corticosteroids and antibiotics. No signs of pyoderma gangrenosum developed at the surgical wound site, and the axillary lesions showed constant improvement until healing with scar tissue. CONCLUSIONS In our patient, the preoperative steroid treatment, perioperative antibiotics, and soft tissue protective surgical technique led to successful management of this rare coincidence.

股骨颈骨折和坏疽性脓皮病患者的髋关节置换术：一例病例并文献复习。

背景技术坏疽性脓皮病是一种病因不明的罕见溃疡性皮肤病，使其与整形外科创伤的巧合成为罕见的挑战。当进行外科手术时，患者在皮肤受伤时有现存病变进展和新病变发展的风险。据我们所知，这是关于活动性坏疽性脓皮病期间与疾病无关的外科手术文献的首次报道。病例介绍我们介绍了一例高加索患者的股骨颈骨折，伴有坏疽性脓皮病位于腋窝。使用全身性皮质类固醇减少疾病活动后，可以安全地进行髋关节置换术。组织保护性伤口闭合与围手术期使用的皮质类固醇和抗生素一起使用。在手术伤口处未出现坏疽脓皮病的迹象，并且腋窝病变显示出持续的改善，直到疤痕组织愈合为止。结论在我们的患者中，术前使用类固醇治疗，围手术期应用抗生素和软组织保护性手术技术可成功管理这种罕见的巧合。
