Abstract

Primary intraosseous mucoepidermoid carcinoma of the jawbones is an extremely rare malignant salivary gland tumour constituting 2- 4.3% of all the reported mucoepidermoid carcinomas. We report a case of intraosseous mucoepidermoid carcinoma of the mandible in an 80-year old female patient developing from a previously diagnosed dentigerous cyst. An excisional biopsy was performed and the histopathological features confirmed low grade-cystic intraosseous mucoepidermoid carcinoma. The origin of central mucoepidermoid carcinoma could be suggested to be from the epithelial lining of previously diagnosed dentigerous cyst. Thus, emphasizing the need for careful examination of the entire excision specimen to rule out such neoplastic transformation of epithelial lining of odontogenic cyst and provide appropriate and effective treatment.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
