Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic neoplasm of the jaws, accounting for less than 3% of all odontogenic tumors. It rarely extends into the maxillary sinus. Till date, six cases involving maxillary sinus have been reported. In this paper, we report the seventh case of a 52-year-old male with CEOT in maxilla extending from distal surface of the right maxillary canine to retromolar area and involving maxillary sinus with no association with impacted teeth. The diagnosis was confirmed by aspiration cytology and histologically, the tumor was composed of sheets of epithelial cells, with areas of clear cell changes. The presence of clear cells in the histological sections, accounts for the aggressive nature of the tumor simulating the clinical appearance. Prevention of recurrence can be achieved by radical resection.
牙源性钙化上皮瘤（CEOT）是一种罕见的颌骨良性牙源性肿瘤，占所有牙源性肿瘤的比例不到3%。它很少累及上颌窦。迄今为止，已报道6例累及上颌窦的病例。在本文中，我们报告第7例病例，一名52岁男性，上颌骨发生牙源性钙化上皮瘤，范围从右上颌尖牙远中面至磨牙后区，并累及上颌窦，与阻生牙无关。通过针吸细胞学检查确诊，组织学上肿瘤由上皮细胞片组成，伴有透明细胞改变区域。组织学切片中透明细胞的存在解释了该肿瘤模拟临床外观的侵袭性本质。通过根治性切除可预防复发。
