Pleomorphic Adenoma of the Deep Lobe of the Parotid Gland Presenting With Dysphagia: A Case Report

Abstract

Dysphagia is a common clinical manifestation with a wide range of underlying medical conditions. Here, we present a case of a 52-year-old man with dysphagia, found to have a pleomorphic adenoma in the right parotid gland causing significant pharyngeal wall distortion. The patient underwent a successful total parotidectomy with facial nerve preservation using a transparotid-transcervical approach. A histological examination confirmed the diagnosis. While the patient experienced temporary facial weakness postsurgery, he had a successful recovery with no further issues during the 2-year follow-up. This case highlights the importance of considering parotid gland tumors as a potential cause of dysphagia when a mass is present in the oropharynx. Additionally, it demonstrates the feasibility of using a transparotid-transcervical approach for total parotidectomy with facial nerve preservation.

Surgical management of a giant parotid gland pleomorphic adenoma in Northern Sri Lanka: A case report

“…It is more commonly found in the superficial lobe of the parotid gland. Less than 20 % of pleomorphic adenomas only arise in the deep lobe of the parotid gland [ 4 ]. Our case also showed involvement of the deep lobe of the parotid gland, which is a rare occurrence.…”

“…It is a benign mixed tumour as it has a dual origin from epithelial and mesangial elements [ 2 ]. There is a popular rule of 80s; 80 % of all salivary tumours originating from the parotid gland, 80 % of them are benign, 80 % of benign parotid tumours are PA, and 80 % of them involve the parotid gland's superficial lobe [ 3 , 4 ]. Other origins are from minor salivary gland (10 %) where hard palate being most common site and submandibular glands (5 %).…”
