Abstract: Pleomorphic adenoma, also known as mixed tumor, is the most common neoplasm arising from salivary glands, accounting for approximately 81.2% of all benign tumors in salivary glands. The parotid gland accounts for 85% of these tumors, with 10% arise in the submandibular gland and only 0.3% in the sublingual gland. The aim of this study is to describe the specific management of pleomorphic adenoma in its unusual location. Here, we present a case of pleomorphic adenoma of the sublingual gland in a 62-year-old woman, manifesting with a painless mass in the floor of the mouth for 5 years, appearing as a well-limited hypodense tissue lesion, enhanced after contrast injection, in the sublingual region and extending to the right mylohyoid muscle in computed tomography imaging. The tumor and sublingual gland were resected under general anesthesia. The histopathological diagnosis was pleomorphic adenoma. No evidence of recurrence was detected after three years follow-up.
