Sarcoma developing in association with a metallic orthopedic procedure is an uncommon but well-recognized complication in mammals. We report on a synovial sarcoma that developed at the site of an intramedullary pin after surgery to treat a bone fracture. A 17-year-old female peach-faced lovebird (Agapornis roseicollis) developed a spherical mass on the distal right dorsal wing at a site that was previously fractured and surgically repaired with an indwelling intramedullary pin. The right wing was amputated at the scapulohumeral joint. One year later, the bird died. Postmortem examination revealed metastases in the right lung, left thoracic wall, and proventricular serosa. Histologically, the tumor had a characteristic biphasic pattern. The tumor was immunohistologically and ultrastructurally identified as a synovial sarcoma. This is the first report of a suspected fracture-associated sarcoma in a bird.
与金属骨科手术相关的肉瘤在哺乳动物中是一种罕见但已得到充分认识的并发症。我们报告了一例在治疗骨折的手术后，髓内针部位发生的滑膜肉瘤。一只17岁的雌性桃脸牡丹鹦鹉（Agapornis roseicollis）在右背侧翅远端先前骨折并通过留置髓内针手术修复的部位出现了一个球形肿块。右翅在肩胛肱关节处被截肢。一年后，这只鸟死亡。尸检发现右肺、左胸壁和前胃浆膜有转移。组织学上，肿瘤具有典型的双相模式。通过免疫组织化学和超微结构鉴定该肿瘤为滑膜肉瘤。这是鸟类中疑似骨折相关性肉瘤的首例报告。
