A case of pleomorphic adenoma on the upper lip

Abstract

Pleomorphic adenoma is the most common salivary neoplasm and occurs mainly in major salivary glands, especially the parotid gland. It is characterized by a variable histopathologic appearance, and a high recurrence rate with malignant transformation depending on previous surgical treatment method used. A benign mixed tumor occurring in minor salivary glands is believed to show the same clinicopathologic appearance and a relatively low recurrence rate as in major salivary glands. Pleomorphic adenoma is the most common intraoral salivary gland tumor and characteristically presents as a slow, painless growth. Herein, we report a case of a patient with pleomorphic adenoma that affected the upper lip.
