Pleomorphic adenoma is the most common salivary gland tumor. It frequently develops in the parotid and palatine glands, but rarely in the sublingual gland. This paper reports a case of pleomorphic adenoma of the sublingual gland in a 72-year-old woman who visited our clinic with the chief complaint of a mass in the right mouth floor. A well-defined, elastic hard mass was identified in the region. MR image findings did not detect the right normal sublingual gland. Based on the clinical diagnosis of sublingual gland tumor, the tumor was resected under general anesthesia and was histopathologically diagnosed as a pleomorphic adenoma. There has been no sign of recurrence for 3 years after the surgery.
