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 male 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 three months. After fine needle aspiration biopsy the mass was diagnosed as pleomorphic adenoma. The patient 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 deep lobe of the parotid gland and extend into the PPS.

“…Core needle biopsy is also a choice of modality. However, literature shows that fine needle aspiration is more advantageous when compared to core needle biopsy is terms of potentially increased risk of tumour spillage, capsule rupture and tumour recurrence, which ultrasound-guided core needle biopsy is associated with (depending on needle diameter and sample volume) [20]. In our opinion, open biopsy is not necessary.…”

The Role of Glutathione S-Transferases in Pleomorphic Adenomas of the Salivary Glands

“…It's a noncancerous tumor made up of epithelial and myoepithelial cells (Khandker et al, 2019). The parotid and submandibular glands are the most prevalent sites of PA (Polat et al, 2013). PA can affect people of any age, however, it is more common in people between the ages of 30 and 50, with a small female predominance (Alves et al, 2002;Fatah and Khaleel, 2016).…”
