Synovial chondromatosis is a benign disease that rarely affects the temporomandibular joint (TMJ). It can be seen commonly in the superior joint space and presents with various signs and symptoms according to the stage of progression. Sometimes it presents as a large swelling in the preauricular area with or without cranial extension, and the clinical and radiographic findings may be misdiagnosed as other benign or malignant diseases of TMJ. Therefore, we report an uncommon case of synovial chondromatosis presenting as a large preauricular mass arising from the inferior joint space of the TMJ with bony resorption of the mandibular condyle, which mimicked osteochondroma.
滑膜软骨瘤病是一种罕见累及颞下颌关节（TMJ）的良性疾病。它常见于关节上间隙，根据疾病进展阶段表现出各种体征和症状。有时它表现为耳前区的巨大肿胀，可伴有或不伴有向颅部扩展，其临床和影像学表现可能被误诊为颞下颌关节的其他良性或恶性疾病。因此，我们报告一例罕见的滑膜软骨瘤病病例，该病例表现为起源于颞下颌关节下间隙的巨大耳前肿物，并伴有下颌髁突骨质吸收，酷似骨软骨瘤。
