一个透明细胞变异的钙化上皮牙源性肿瘤（CCEOT）影响骨外网站的描述。一位60岁男性病患，因前颚舌侧牙龈肿胀而就诊。活检结果提示透明细胞牙源性癌，并进行下颌骨边缘切除术。切除的标本由嗜酸性和透明细胞组成，并有淀粉样物质沉积。透明细胞呈PAS阳性颗粒。在切除的病变中没有钙化。根据这些特征，最终诊断为外周CCEOT无钙化。3年随访后无明显复发迹象。
A clear cell variant of calcifying epithelial odontogenic tumor (CCEOT) affecting an extraosseous site is described. A 60-year-old male patient presented with gingival swelling on the lingual side of the anterior mandible. The results of biopsy suggested clear cell odontogenic carcinoma, and marginal resection of the mandible was performed. The resected specimen was composed of eosinophilic and clear cells with deposits of amyloid-like material. The clear cells exhibited granules that were positive for PAS. There was no calcification in the resected lesion. Based on these features, the conclusive diagnosis was peripheral CCEOT without calcification. No signs of recurrence were evident after 3 years of follow-up.
