The ultrastructural characteristics of multinuclear foreign-body giant cells (MCG) in a human vocal cord Teflon granuloma are described. The cells were found to contain varying numbers of Teflon particles within their cytoplasm. The particles, rounded or oval in shape, were surrounded by a rather electron-dense membrane. Numerous lysosomal structures were discerned within the cells. The fine structure of MCG in granulomas induced by foreign materials other than Teflon has already been described in man as well as in several experimental animals, and the Teflon MCG resembled these cells in many respects. No evidence of malignant change was found.
描述了人声带聚四氟乙烯肉芽肿中多核异物巨细胞（MCG）的超微结构特征。发现这些细胞的细胞质内含有数量不等的聚四氟乙烯颗粒。这些颗粒呈圆形或椭圆形，被一层电子密度相当高的膜所包围。细胞内可辨认出许多溶酶体结构。除聚四氟乙烯外的其他异物所致肉芽肿中MCG的精细结构已在人体及多种实验动物中有所描述，聚四氟乙烯MCG在许多方面与这些细胞相似。未发现恶变证据。
