Parotid Tail Pleomorphic Adenoma Extending to the Parapharyngeal Space

Abstract

Parapharyngeal space tumors are rare, accounting for 0.5% of head and neck neoplasms. Most of them are benign and originate in the salivary glands, especially the pleomorphic adenoma. We presented a 47-year-old man with parotid tail pleomorphic adenoma extending to the parapharyngeal space. The patient applied to our clinic with the complaints of a painless mass on his neck and in his mouth for 3 months. After fine needle aspiration biopsy, the mass was diagnosed as pleomorphic adenoma. The patient was hospitalized and operated in our clinic. As we see in literature review, parapharyngeal space tumors are rare, and most of them are pleomorphic adenomas arising from the deep lobe of the parotid gland and extend into the PPS.
