目标。据报道，大约8%的钙化上皮性牙源性肿瘤（CEOT）病例中存在透明细胞。本研究的目的是描述透明细胞CEOT （CCEOT）的临床和影像学特征。研究设计。通过对1958年至2001年的文献回顾，我们发现18例CCEOT，并新增1例（共19例，中心12例，外周7例）。14例（74%）肿瘤位于下颌骨，中心病变倾向于后区，周围病变倾向于前双尖区。x线表现：50%放射透光，50%混合放射透光-不透光；单房的92%;64%明确的无皮质边界，27%明确的皮质边界，9%不规则边界。与没有透明细胞成分的CEOT（6.7%）相比，皮质穿孔很常见（67%）。中心灶复发率为17%，外周灶无复发。CCEOT是CEOT的不同变体；其高倾向于皮质穿孔可能表明更具攻击性的行为。
Objectives. Clear cells have been reported in approximately 8% of cases of calcifying epithelial odontogenic tumor (CEOT). The purpose of this study was to describe the clinical and radiographic features of clear-cell CEOT (CCEOT).Study design. Eighteen cases of CCEOT were identified by review of the literature from 1958 to 2001, and a new one was added (total 19; 12 central, 7 peripheral).Results. Fourteen tumors (74%) were located in the mandible, with the central lesions favoring the posterior area and the peripheral lesions the anterior-bicuspid area. Radiographic features were as follows: 50% radiolucent, 50% mixed radiolucent-radiopaque; 92% unilocular; 64% well-defined noncorticated borders, 27% well-defined corticated borders, 9% irregular borders. Cortical perforation was common (67%) compared with CEOT without a clear-cell component (6.7%). Recurrence was reported in 17% of the central lesions and none of the peripheral ones.Conclusions. CCEOT is a distinct variant of CEOT; its high tendency for cortical perforation may indicate a more aggressive behavior.
