Synovial chondromatosis (SC) is a chronic process, defined as a reactive cartilaginous proliferation, characterized by formation of cartilaginous nodules, usually loose in the joint space of the synovial membrane. It mainly affects large joints such as knee, hip, shoulder, and elbow, commonly in male patients. However, its manifestation in the Temporomandibular joint (TMJ), is a rare finding, occurring predominantly in females. This paper reports a case of a woman who presented to the service of Stomatology complaining of mouth opening limitations and pain in her left pre-auricular region. After clinical and radiographic analyses, the condition was diagnosed as SC of the TMJ. The loose bodies within the TMJ were removed under general anesthesia. Histological and follow-up features of this lesion are also discussed. To our knowledge, this is the second report of SC of the TMJ in Brazil.
滑膜软骨瘤病（SC）是一种慢性病变，定义为一种反应性软骨增生，其特征是形成软骨结节，通常在滑膜的关节间隙内松散存在。它主要影响膝关节、髋关节、肩关节和肘关节等大关节，男性患者较为常见。然而，其在颞下颌关节（TMJ）的表现较为罕见，主要发生在女性患者中。本文报告了一例女性患者，她因张口受限和左耳前区疼痛就诊于口腔科。经过临床和影像学分析，该病例被诊断为颞下颌关节滑膜软骨瘤病。在全身麻醉下切除了颞下颌关节内的游离体。本文还讨论了该病变的组织学特征和随访情况。据我们所知，这是巴西第二例颞下颌关节滑膜软骨瘤病的报告。
