A Japanese male aged 61 presented with persistent pain in the left posterior area of the mandible for several weeks. A panoramic X-ray revealed a unilocular lesion showing characteristics of a dentigerous cyst associated with an impacted third molar. A cystectomy was performed and histopathological examination revealed a cystic lesion with a fibrous wall. The lumen was covered with non-keratinizing squamous cells with obvious intercellular bridges, which were intermingled with partially ciliated goblet-cell-type mucous and columnar cells. Such cystic lesions should be carefully examined to distinguish them from the glandular odontogenic cyst and central mucoepidermoid carcinoma of the jawbone.
一位 61 岁的日本男性出现左下颚后部持续性疼痛数周。全景 X 光片显示单侧病变，具有与阻生第三磨牙相关的含牙囊肿特征。进行了囊肿切除术，组织病理学检查显示囊腔病变伴纤维壁。腔隙被覆非角化复层鳞状细胞，有明显的细胞间桥，间杂有部分纤毛杯状细胞型黏液和柱状细胞。此类囊性病变应仔细检查，以与颌骨的腺牙源性囊肿和中央黏液表皮样癌相鉴别。
