An 85-year-old man was found to have a calcified mass protruding from the joint space of the right temporomandibular joint (TMJ). Microscopically, the removed mass consisted of chondromyxoid tissue with atypical chondrocytes, resembling a cartilaginous tumor. However, the chondromyxoid tissue contained abundant deposits of rod-shaped to rhomboid crystals which proved to be calcium pyrophosphate dihydrate (CPPD) crystals. The review of the literature revealed that tophaceous pseudogout was the most common variant of CPPD deposition disease involving the TMJ.
一名85岁男性被发现右颞下颌关节（TMJ）关节间隙有一钙化肿物突出。显微镜下，切除的肿物由含有非典型软骨细胞的软骨黏液样组织构成，类似软骨肿瘤。然而，该软骨黏液样组织含有大量杆状至菱形晶体沉积，经证实为二水焦磷酸钙（CPPD）晶体。文献回顾显示，痛风石性假痛风是累及TMJ的CPPD沉积病最常见的变异型。
