Mucoepidermoid carcinomas (MECs) arising within the jaws as primary central bony lesions are termed central MECs. Central MECs are extremely rare, comprising 2-3% of all mucoepidermoid carcinomas. We herein report a rare case of central MEC of the maxilla in a 52-year-old male whose plain radiographs showed a "ground glass" pattern and computed tomographic images, a hypodense mass with numerous calcifications. To the best of our knowledge, this is the first report of central MEC showing a "ground glass" appearance.

发生于颌骨内的原发性中央骨病变的黏液表皮样癌（MEC）被称为中央型黏液表皮样癌。中央型黏液表皮样癌极为罕见，占所有黏液表皮样癌的2% - 3%。我们在此报告一例52岁男性上颌骨中央型黏液表皮样癌的罕见病例，其平片显示“磨玻璃”样表现，计算机断层扫描图像显示为一个有大量钙化的低密度肿块。据我们所知，这是中央型黏液表皮样癌呈现“磨玻璃”外观的首例报告。
