윗입술에 발생한 다형 선종

초록

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.
