Synovial sarcoma is a relatively common periarticular soft tissue malignancy, occurring mostly in the extremities of younger patients. Occasionally, diversity in its clinical features may lead to misdiagnosis and inappropriate management. The authors report herein a unique case of a patient who underwent a primary total knee arthroplasty to treat osteoarthritis. During the operation, a mass was discovered but was attributed to synovitis. Biopsy revealed a rare intra-articular synovial sarcoma. The patient underwent reoperation with wide excision and endoprosthesis placement and is disease-free at the 8-year follow-up.
滑膜肉瘤是一种相对常见的关节周围软组织恶性肿瘤,多发生于年轻患者的四肢。偶尔,其临床特征的多样性可能导致误诊和不恰当的治疗。本文作者报告了一例独特的病例,该患者因骨关节炎接受了初次全膝关节置换术。手术过程中发现了一个肿块,但被认为是滑膜炎。活检显示为罕见的关节内滑膜肉瘤。患者接受了再次手术,进行了广泛切除并置入了假体,在8年的随访中无疾病复发。
