The ultrastructural features of a juvenile ossifying fibroma of the maxilla are described. The stromal portion of the tumor was composed of osteoblasts and to a lesser extent of fibroblasts. The bone spicules were rimmed by osteoblasts and osteoclasts. Calcification was seen to occur along the collagen fiber matrix, corresponding to calcification of osteoid, and also in the form of intracellular and extracellular crystallization. The latter form of calcification corresponded to so-called psammoma-like bodies, and was considered characteristic of this subtype of ossifying fibroma.
描述了一例上颌骨青少年骨化性纤维瘤的超微结构特征。肿瘤的间质部分由成骨细胞组成，成纤维细胞较少。骨小梁边缘有成骨细胞和破骨细胞。可见钙化沿胶原纤维基质发生，对应于类骨质的钙化，也呈细胞内和细胞外结晶的形式。后一种钙化形式对应于所谓的砂粒体样小体，被认为是这种骨化性纤维瘤亚型的特征。
