Atypical Presentation of Pleomorphic Adenoma: Case Report

Introduction: Salivary gland tumours are uncommon, accounting for less than 5% of all head and neck neoplasms. Most of the malignancies in this area are located in the major salivary glands, which include the parotid, submandibular, and sublingual glands. The numerous small salivary glands can be found under the mucosa all throughout the aerodigestive tract. They make up less than 5% of all tumours of the salivary glands.

Presentation of Case: A 50-years old patient presented to our department for discomfort over the Right half of the head and giddiness intermittently for a period of about 13 months, pain over the right side of the neck, difficulty in swallowing, and swelling of the right tonsil for about four months. On examination of the throat, a moderately enlarged right tonsil with minimal congestion was seen. We performed a tonsillectomy and the anatomopathological examination concluded to pleomorphic adenoma.

Conclusion: Pleomorphic adenoma is a rare benign tumor of Salivary gland; it’s exceptional to be located in the tonsil. The treatment choice of pleomorphic adenoma is wide surgical excision. Because of high recurrence rate after surgical excision, long-term follow-up is necessary.
