Rhabdomyosarcomeis a commun tumor in children with all its types (pleomorphic, embryonal,alveolarand spindle cell rhabdomyosarcoma). However, it is a very rare tumor in adults, the commun type isthe pleomorphicrhabdomyosarcoma but it is very rare in the head and neck region. The diagnosis of the pleomorphic RMS is made by the histopathologic study, this shows the interest of a biopsy before the surgicalprocedure. The treatment of patients with malignant mesenchymal tumors of the head and neck region is multidisciplinary (radical surgery with postoperative radiotherapy and or chemotherapy) with poor prognosis.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
