The objective of this study was to supplement the current ameloblastoma database by reporting the clinicopathologic features of ameloblastoma from Asia and North America.
Biopsy records of the participating institutes were reviewed for lesions diagnosed as ameloblastoma during the years 1993 to 2009. Slides were reclassified according to the World Health Organization Classification of Odontogenic Tumors in 2005. Clinical information and radiographic features were collected and analyzed.
The mean age of the patients ± SD was 38.27 ± 17.78 years; 662 patients (51.36%) were men. Mandible (84.26%) outnumbered maxilla and other locations combined in all countries. The number of multilocular radiolucencies (43.40%) was comparable with that of unilocular radiolucencies (42.04%). Follicular pattern was the most common histopathologic pattern (27.70%), followed by plexiform (21.10%) and unicystic pattern (20.71%), respectively.
The clinicopathologic features of ameloblastomas in the present study show some similarities with previous studies; however, minor differences exist.
本研究旨在通过报告亚洲和北美的成釉细胞瘤的临床病理特征来补充当前的成釉细胞瘤数据库。
对参与研究的机构的活检记录进行了回顾，以确定在 1993 年至 2009 年期间诊断为成釉细胞瘤的病变。根据 2005 年世界卫生组织牙源性肿瘤分类重新对切片进行了分类。收集并分析了临床信息和影像学特征。
患者的平均年龄 ± SD 为 38.27 ± 17.78 岁；662 名患者（51.36%）为男性。在所有国家中，下颌骨（84.26%）比上颌骨和其他部位的总和还要多。多房性透光区（43.40%）的数量与单房性透光区（42.04%）相当。滤泡型是最常见的组织病理学类型（27.70%），其次是丛状型（21.10%）和单囊型（20.71%）。
本研究中成釉细胞瘤的临床病理特征与以往的研究有一些相似之处，但也存在一些细微的差异。
