Pyoderma gangrenosum after hip hemiarthroplasty; a case report.

Pyoderma gangrenosum is a severe and rare neutrophilic disorder that can present as a complication following any kind of surgery, usually after breast and abdominal surgery. This condition mimics infection, delaying prompt diagnosis and appropriate treatment with high dose of corticosteroids. We describe a case of pyoderma gangrenosum after hip hemiarthroplasty, in an 86-year-old woman, who sustained a neck of femur fracture after a simple fall. The patient was diagnosed 2 weeks postoperatively with pyoderma gangrenosum through a biopsy with clinical manifestations from other systems such as seizures and atrial fibrillation.
