The light and electron microscopic features of synovial chondromatosis of the temporomandibular joint of one patient are presented. The affected synovial membrane and the cartilaginous nodules, which were freely movable in the joint space as well as attached to or incorporated in the synovial membrane, were examined. Light microscopic observation revealed metaplastic formation of these nodules within the subintima of the synovial membrane. Different stages of development of the nodules were observable. Electron microscopic examination of the cartilaginous nodules revealed features of mature chondrocytes well endowed with rough-surfaced endoplasmic reticulum and Golgi apparatus. The synovial intimal cells had a differentiated ultrastructural appearance. Several cytoplasmic organelles of the chondrocytes and intimal cells are described. The results of this study support the benign nature of synovial chondromatosis.
本文呈现了1例颞下颌关节滑膜软骨瘤病患者的光镜和电镜特征。对受累的滑膜以及关节腔内可自由移动、附着于滑膜或包埋于滑膜内的软骨结节进行了检查。光镜观察显示，这些结节在滑膜内膜下层呈化生形成。可观察到结节的不同发育阶段。对软骨结节的电镜检查显示，成熟软骨细胞具有丰富的粗面内质网和高尔基体。滑膜内膜细胞具有分化的超微结构外观。描述了软骨细胞和内膜细胞的几种细胞质细胞器。本研究结果支持滑膜软骨瘤病的良性性质。
