Abstract

OBJECTIVE: The aim of this study was to report the clinicopathologic features of 62 cases of central odontogenic fibroma (COdF). STUDY DESIGN: Clinical and radiographic data were collected from the records of 13 oral pathology laboratories. All cases were microscopically reviewed, considering the current World Health Organization classification of tumors and were classified according to histopathologic features. RESULTS: There were 43 females and 19 males (average age 33.9 years; range 8-63 years). Clinically, COdF lesions appeared as asymptomatic swellings, occurring similarly in the maxilla (n = 33) and the mandible (n = 29); 9 cases exhibited palatal depression. Imaging revealed well-defined, interradicular unilocular (n = 27), and multilocular (n = 12) radiolucencies, with displacement of contiguous teeth (55%) and root resorption (46.4%). Microscopically, classic features of epithelial-rich (n = 33), amyloid (n = 10), associated giant cell lesion (n = 7), ossifying (n = 6), epithelial-poor (n = 3), and granular cell (n = 3) variants were seen. Langerhans cells were highlighted by CD1a staining in 17 cases. Most patients underwent conservative surgical treatments, with 1 patient experiencing recurrence. CONCLUSIONS: To the best of our knowledge, this study represents the largest clinicopathologic study of COdF. Most cases appeared as locally aggressive lesions located in tooth-bearing areas in middle-aged women. Inactive-appearing odontogenic epithelium is usually observed within a fibrous/fibromyxoid stroma, occasionally exhibiting amyloid deposits, multinucleated giant cells, or granular cells.

摘要

目的:本研究旨在报告 62 例中央性牙源性纤维瘤(COdF)的临床病理特征。

研究设计:从 13 个口腔病理学实验室的记录中收集了临床和影像学数据。所有病例均进行了显微镜检查,考虑到当前的世界卫生组织肿瘤分类,并根据组织病理学特征进行了分类。

结果:共有 43 名女性和 19 名男性(平均年龄 33.9 岁;范围 8-63 岁)。临床上,COdF 病变表现为无症状肿胀,同样发生在上颌(n=33)和下颌(n=29);9 例出现腭部凹陷。影像学显示界限清楚的、根尖间单房(n=27)和多房(n=12)的透光区,伴有相邻牙齿的移位(55%)和牙根吸收(46.4%)。显微镜下,可见富含上皮(n=33)、淀粉样变(n=10)、伴发巨细胞病变(n=7)、骨化(n=6)、上皮缺乏(n=3)和颗粒细胞(n=3)等多种变体。17 例中用 CD1a 染色突出显示朗格汉斯细胞。大多数患者接受了保守的手术治疗,1 例患者复发。

结论:据我们所知,这是对 COdF 进行的最大规模的临床病理研究。大多数病例表现为位于中年女性牙区的局部侵袭性病变。通常在纤维/纤维粘液样基质中观察到不活跃的牙源性上皮,偶尔出现淀粉样物质沉积、多核巨细胞或颗粒细胞。
