Central Mucoepidermoid Carcinoma of the Maxilla, a Challenging Diagnosis

Objective: To present a pictorial review on central mucoepidermoid carcinoma. Case report: Central mucoepidermoid carcinoma (CMEC), also known as intraosseous mucoepidermoid carcinoma (IMEC), is an extremely rare disease (less than 2-4% of all MEC). However, CMEC is the most frequent malignant salivary gland tumour found in intraosseous locations. Due to this unusual location, diagnosis of CMEC can be challenging. Therefore, CMEC is often mistaken for other intraosseous or odontogenic pathologies. Radiological assessment shouldinclude panoramic X-Ray, CBCT and thoracic CT, which should be performed after diagnosis. The recommended treatment includes radical resection surgery, followed by radiotherapy if indicated. A long-term follow-up is recommended for up to 10 years. Conclusion: The authors experienced the challenging diagnosis of CMEC through the case of a patient who presented with a slowly growing palatal mass.
