A Rare Tumor of the Parotid Gland: A Case Report and Review of the Literature

Abstract

We report a rare case of a parotid oncocytoma in a 63-year-old woman. It is a rare benign tumor accounting for less than 1.5% of all salivary gland tumors. It is known as the parotid mitochondrioma because it is made of cells rich in mitochondria with granular cytoplasm. It is a rare entity poorly documented in the literature, and there are no pathognomonicsymptoms or imaging, which makes the diagnosis of this tumor challenging.Surgery is the main treatment, and the diagnosis is confirmed by the histological study of the specimen. Through this observation, and in light of the literature, we will underline the anatomoclinical and radiological peculiarities of this tumor, to induce clinicians to consider this histological type.
