Ameloblastomas seldom cause diagnostic difficulties due to classic histopathological presentations. Adenoid ameloblastoma is a rare variant in this category which can cause problem in diagnosis due to the presence of areas resembling adenomatoid odontogenic tumor (AOT) and occurrence of varying degrees of dentinoid formation. In this article, we report a case of adenoid ameloblastoma with dentinoid, which was diagnosed accurately after the third recurrence. To the best of our knowledge, so far, only 13 cases have been reported of tumors that histologically show features of amelobalstoma and AOT with hard tissue formation. The recurrences were due to under diagnosis of the lesion followed by a conservative treatment.
由于具有典型的组织病理学表现，成釉细胞瘤很少引起诊断困难。腺样成釉细胞瘤是该类型中的一种罕见变异型，由于存在类似腺样牙源性肿瘤（AOT）的区域以及不同程度的牙本质样形成，可导致诊断困难。在本文中，我们报告了一例伴有牙本质样结构的腺样成釉细胞瘤病例，该病例在第三次复发后才得以准确诊断。据我们所知，迄今为止，仅有13例组织学表现为成釉细胞瘤和AOT特征并伴有硬组织形成的肿瘤病例被报道。复发是由于对病变诊断不足，随后采取了保守治疗。
