The pleornorphic adenoma in the oral cavity is a tumor originating from both major and minor salivary glands. This tumor is the most common neoplasm among all salivary gland tumors and its incidence is the highest concerning the parotid gland in major salivary glands and at the palate in minor salivary glands. However, it is said that this tumor seldom occurs on the lip.
We have recently experienced one case of pleornorphic adenoma considered to have originated at the minor salivary gland in the upper lip.
