摘要

颞下颌关节（TMJ）和颞下窝（ITF）肿瘤虽然罕见，但由于其症状无特异性，诊断起来非常复杂。滑膜肉瘤占成人软组织肉瘤的5%-10%，在头颈部并不常见，在颞下颌关节/ITF区域尤为罕见。我们介绍了一例单相滑膜肉瘤病例，患者为一名 24 岁男性，左侧颞下颌关节/ITF 受累，耳前疼痛剧烈，被误诊为颞下颌关节紊乱 3 年。经过深入评估，发现颞下颌关节附近有一个 40 毫米的肿瘤，于是进行了广泛切除并立即进行了重建，随后进行了术后放疗和辅助化疗。早期和 3 年后肿瘤进展的磁共振成像照片、最初的症状和体征以及术中图像可用于评估肿瘤的演变情况。

Synovial Sarcoma of the Temporomandibular Joint and Infratemporal Fossa: A Case Report

Temporomandibular joint (TMJ) and infratemporal fossa (ITF) tumors, even though rare, present diagnostic complexities due to their nonspecific symptoms. Synovial sarcoma comprises 5-10% of adult soft-tissue sarcomas and is uncommon in the head and neck and exceptionally rare in the TMJ/ITF region. We presented a case of monophasic synovial sarcoma affecting the left TMJ/ITF in a 24-year-old man with severe preauricular pain who was misdiagnosed with temporomandibular disorder for 3 years. When in-depth evaluations uncovered a 40 mm tumor adjacent to the TMJ, extensive resection and immediate reconstruction were conducted, followed by postoperative radiotherapy and adjuvant chemotherapy. Magnetic resonance imaging photos of the early stage and after 3 years of tumor progression, initial signs and symptoms, and intraoperative images allowed tumor evolution assessment.
