Abstract：
UNASSIGNED: Diagnosis of odontogenic tumors can be challenging due to their rarity and diverse morphology. The clinical diagnosis could be suspected when it had raised near the tooth. But, when their location is not typical, like inside the paranasal sinuses, the diagnosis is less easy. Maxillary ameloblastomas are rare with only sparse information on their epidemiological, histological and effective management.
METHODS: A 54-year-old woman presented with ameloblastoma of the left maxillary sinus. Intraoral examination revealed partially edentulous with a 2 cm painless ulceration of the left alveolar process of the maxilla. A biopsy was performed which showed a follicular ameloblastoma. The treatment was surgical. She had a combined endoscopic and transoral resection of the tumor. The patient was diagnosed with recurrence within 3 months from surgery.
CONCLUSIONS: although rarely reported, clinicians should still suspect and know how to manage such as rare and locally invasive tumor as a maxillary ameloblastoma.
CONCLUSIONS: As odontogenic tumors are rare, some entities are infrequently encountered, making the diagnosis more difficult. Clinicians, oral and maxillofacial surgeons, and oral pathologists should be familiar with the ameloblastoma and its differential diagnosis for accurate diagnosis and management.

摘要：
■由于牙源性肿瘤的稀有性和形态多样性，其诊断可能具有挑战性。当它在牙齿附近升起时，可能会怀疑临床诊断。但是,当他们的位置不典型时，就像在鼻旁窦里面,诊断不那么容易。上颌成釉细胞瘤很少见，只有很少的流行病学信息，组织学和有效的管理。
方法：一名54岁女性患者出现左上颌窦成釉细胞瘤。口内检查显示部分无牙，上颌骨左牙槽突无痛性溃疡2厘米。进行活检，显示滤泡性成釉细胞瘤。治疗是手术。她进行了内窥镜和经口联合切除肿瘤。患者在手术后3个月内被诊断为复发。
结论：虽然很少报道，临床医生仍应怀疑并知道如何将诸如罕见和局部浸润性肿瘤作为上颌成釉细胞瘤进行治疗。
结论：由于牙源性肿瘤很少见，一些实体很少遇到，使诊断更加困难。临床医生,口腔和颌面外科医生，口腔病理学家应熟悉成釉细胞瘤及其鉴别诊断，以便准确诊断和治疗。
