The ultrastructures of five examples of giant cell tumors of the tendon sheath and one example of pigmented villonodular synovitis were studied. The giant cell tumors were composed mostly of A and B types of synovial cells. Also present were fibroblastic cells with intracytoplasmic filaments with densities (myofibroblasts) as well as "monocytic" and "lymphocytic" cells. The giant cells seemingly were derived from the fusion of synovial cells of A type, whereas foam cells were derived from both A and B cells. Both the giant cell tumors and the pigmented synovitis are considered to be reactive and borderline proliferative lesions of the synovial cells.
对五例腱鞘巨细胞瘤及一例色素沉着绒毛结节性滑膜炎的超微结构进行了研究。腱鞘巨细胞瘤主要由A型和B型滑膜细胞组成。还存在具有胞质内细丝及密度的成纤维细胞（肌成纤维细胞）以及“单核细胞”和“淋巴细胞”。巨细胞似乎源自A型滑膜细胞的融合，而泡沫细胞则源自A型和B型细胞。腱鞘巨细胞瘤和色素沉着性滑膜炎均被认为是滑膜细胞的反应性和交界性增殖性病变。
