钙化性牙源性上皮肿瘤是一种良性的牙源性上皮肿瘤，好发于下颌后部。骨外CEOT是这种肿瘤最罕见的形式之一，在文献中很少有涉及上颌牙龈的病例报道。在这里，我们介绍了一个病例，该病例在11年的时间里显示左上颌牙龈区域进行性增大。临床检查显示，在侧切牙和犬齿附近有一个溃疡肿块，尺寸为52 x 38 mm。组织学上，肿瘤表现为上皮细胞的片状和条索状增生，具有颗粒状的嗜酸性细胞质和圆形至卵圆形的细胞核。在其他区域，上皮细胞显示透明、空泡化的细胞质和嗜酸性、均质物质灶，代表淀粉样沉积。本例骨外透明细胞CEOT被认为是这种肿瘤的一种非常罕见的形式。
Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. Extraosseous CEOT is one of the rarest forms of this tumor, and few such cases involving the maxillary gingiva have been reported in the literature. Here we present a case that showed progressive enlargement in the left maxillary gingival area over a period of 11 years. Clinical examination showed an ulcerated mass measuring 52 x 38 mm located adjacent to the lateral incisor and canine. Histologically, the tumor showed proliferation of sheets and cords of epithelial cells with granular, eosinophilic cytoplasm and round to oval nuclei. In other areas, the epithelial cells exhibited a clear, vacuolated cytoplasm and foci of eosinophilic, homogeneous material representing amyloid deposition. The present case of extraosseous CEOT with clear cells was considered to be a very rare form of this tumor.
