Abstract :
)e origin of a salivary gland tumour is attributed to cells at various levels of di.erentiation which present histologically as diverse
tissues and cellular patterns. Mitochondria-rich, eosinophilic oncocytes are cells commonly encountered in salivary gland
neoplasms. We report a case of mucoepidermoid carcinoma (MEC) in the palate of a 43-year-old female that exhibited
a prominent oncocytic component. While the parotid and submandibular glands have been reported as predominant sites for
oncocytic MEC (OMEC), the palate and minor salivary glands are rare sites for occurrence. Also, most of the reported cases of
OMEC have been histologically of low-grade mucoepidermoid carcinoma with large cystic spaces and good prognosis. In this
article, we discuss the di.erential diagnosis and diagnostic workup of an MEC presenting with oncocytes.
