Ameloblastoma is the second most common benign odontogenic tumor with various histopathologic features. Except for the unicystic type of ameloblastoma, the different microscopic patterns of this tumor show no significant correlation with long-term clinical behavior. During recent decades, additional challenging subtypes of ameloblastoma, including "Keratoameloblastoma" (KA), have been introduced in the literature. Here, we present a case of KA and discuss the important diagnostic microscopic features.
成釉细胞瘤是第二常见的具有多种组织病理学特征的良性牙源性肿瘤。除单囊性成釉细胞瘤外，该肿瘤的不同微观模式与长期临床行为无显著相关性。在最近几十年中，文献中引入了成釉细胞瘤的其他具有挑战性的亚型，包括“角化成釉细胞瘤”（KA）。在此，我们报告一例KA病例并讨论重要的诊断微观特征。
