成釉细胞瘤为牙源性良性肿瘤,多发于下颌骨,生长于上颌骨者较少见。牙源性角化囊肿来源于牙板上皮剩余。但罕见的上颌骨成釉细胞瘤在临床诊断上常与牙源性角化囊肿相混淆,但两者在组织病理学及影像学方面存在着较大差异,不同的生物学特性导致临床手术方式的不同,从而关乎患者预后效果,故临床上两者的鉴别尤为重要。现结合我院上颌骨成釉细胞瘤病例1例分析如下。1病例报告患者,男,52岁,因右后上牙龈肿物快速生长伴牙齿松动2 Ameloblastoma is an odontogenic benign tumor, multiple in the mandible, growing in the maxilla are rare. Odontogenic keratocyst derived from the alveolar epithelium remaining. However, the rare maxillary ameloblastoma is often confused with odontogenic keratocysts in clinical diagnosis. However, there is a great difference in histopathology and imaging between them. Different biological characteristics lead to clinical operation Of the different, which is related to the prognosis of patients, so the distinction between the two clinics is particularly important. Now with our hospital maxillary ameloblastoma case analysis of 1 case as follows. 1 case report patients, male, 52 years old, due to rapid growth of upper right gingival tumor with loosening of the teeth 2
