Aim and Objective
Submandibular oncocytomas are rare benign salivary gland neoplasms, normally involves the parotid gland and few instances are stated in the submandibular gland region. As the clinical and histopathological features are overlapping to another salivary gland tumor like pleomorphic adenoma or warthin tumour, they are often misdiagnosed. They are typically found in patients aged 50–70 years with no gender preference. The aim of this paper is to assess the clinicopathological functions, diagnostic standards and treatment of submandibular gland oncocytomas via a series of three case reports.
Method and Results
We report a three case series of unilateral submandibular gland oncocytoma with female to male ratio 2:1, Size of tumor ranged from 1.8 to 10 cm, 2 cases have painless swelling and one involved tender mass. FNAC and CT scan confirmed the presence of an oncocytoma. The patient underwent unilateral submandibular gland resection and on follow up no evidence of any recurrence was identified.
Conclusion
Submandibular oncocytomas often present as solitary slow growing painless masses, which are firm on clinical examination. CT followed by fine-needle aspiration cytology (FNAC) would be the preferred diagnostic modalities. Due to its low rate of malignant transformation and recurrence, the best treatment is local resection with follow-up as necessary.
