An example of a central odontogenic fibroma is presented. This is a rare, benign neoplasm which affected the molar region of the left side of the mandible of a 63-year-old female Caucasian. Histologically, it consisted of fibroblast-like cells lying in a rather myxomatous delicate collagenous stroma. Few islands of odontogenic epithelium were also found. At the ultrastructural level, the tumour cells contained large numbers of fine filaments with focal densities similar to those described in smooth muscle cells. They also showed a moderately developed r ER. These features are consistent with cells referred to as myofibroblasts.
本文展示了一例中心性牙源性纤维瘤。这是一种罕见的良性肿瘤，发生于一名63岁白种女性下颌骨左侧的磨牙区。组织学上，它由位于黏液样细腻胶原基质中的成纤维细胞样细胞组成。还发现了少量牙源性上皮岛。在超微结构水平上，肿瘤细胞含有大量细丝，其局灶性致密物与平滑肌细胞中描述的相似。它们还显示出中度发达的粗面内质网。这些特征与所谓的肌成纤维细胞一致。
