造釉细胞瘤是上皮性牙源性新生物,在组织学上,它与牙胚的造釉器相似。肿瘤内通常不含钙化组织,并且同一肿瘤内具有不同的组织学表现。肿瘤由上皮和结缔组织间质组成。肿瘤上皮成分常呈团块状,与造釉器相似;也可呈条索状或丛状,有时上皮呈鳞状化生。造釉细胞瘤的超微结构已有报告,其中有的作者对肿瘤内高柱状上皮的结构进行了讨论,并且发现肿瘤上皮与正常釉上皮之间
Ameloblastoma is an epithelial odontogenic neoplasm that is histologically similar to that of the tooth germ enamel. The tumor usually contains no calcified tissue and has different histological manifestations within the same tumor. The tumor consists of epithelial and connective tissue stroma. Tumor epithelial components are usually clumpy and resemble glazes; they may also be cords or plexiforms, and sometimes the epithelium is squamous metaplasia. The ultrastructure of ameloblastomas has been reported, and some authors discuss the structure of high columnar epithelium in tumors and found that there is a relationship between tumor epithelium and normal epithelium.
