The association between the synovial chondromatosis (SC) and the calcium pyrophosphate deposition (pseudogotta) in temporomandibular joint (TMJ) is very rare and has been described just 1 patient in the literature.
A 64-year-old woman was referred to Dipartimento di Scienze Odontostomatologiche e Maxillo-Facciali, Sapienza Università di Roma after complaining about right temporomandibular pain, limitation in mandibular movements, and tumefaction in the right preauricular region. The patient was hospitalized for the surgery. The microscopic examination of the excised material revealed calcium pyrophosphate dihydrate (CPPD) deposits crystals associated with cartilaginous proliferation.
The association between the SC and the calcium pyrophosphate deposition (pseudogotta) is a challenging diagnosis among TMJ neoplasms.
滑膜软骨瘤病（SC）与颞下颌关节（TMJ）中的焦磷酸钙沉积（假痛风）之间的关联非常罕见，文献中仅报道过1例患者。
一名64岁女性因右侧颞下颌疼痛、下颌运动受限及右耳前区肿胀，被转诊至罗马第一大学牙科学与颌面科学系。患者住院接受手术治疗。对切除组织的显微镜检查发现了与软骨增生相关的二水焦磷酸钙（CPPD）沉积晶体。
在颞下颌关节肿瘤中，SC与焦磷酸钙沉积（假痛风）之间的关联是一个具有挑战性的诊断。
