Salivary gland carcinomas are a clinically diverse group of neoplasms with histological patterns overlapping other tumors, thus complicating their diagnosis. Mucoepidermoid carcinoma (MEC), first described by Masson and Berger in 1924, is a well-recognized salivary gland neoplasm, accounting for 5-10% of all salivary gland tumors. MEC frequently involves the major salivary glands and is rarely seen involving the jaws. The biological behavior of MEC is usually more aggressive with higher nodal and metastatic status at the time of presentation, which notably reduces the survival rate. Hence, early and accurate diagnosis utilizing advanced imaging modalities can reduce its morbidity. The present case is a rare presentation of MEC involving the palate, where (18) F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) was utilized for diagnosis and treatment.
