Dentigerous cyst exhibiting prominent mucous cell metaplasia: report of a unique case mimicking central mucoepidermoid carcinoma
MEDICAL MOLECULAR MORPHOLOGY(2021)
摘要
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.
