Abstract
Pleomorphic adenoma is the most common type of salivary gland tumor, frequently occurring in the parotid gland. Here, we report a case of pleomorphic adenoma of the minor salivary gland of the upper lip of a 29-year-old male. He noticed the tumor a year ago, and it gradually increased in size over the past six months. The tumor was painless and movable, with an elastic consistency. The tumor surface was normal, and computed tomography, magnetic resonance imaging, and ultrasound imaging showed that the tumor had clear boundaries. It was approximately 20×20×20mm in size. Tumor excision was performed under general anesthesia, following a clinical diagnosis of left upper lip tumor. The histopathological diagnosis was pleomorphic adenoma. The postoperative course of the patient was uneventful, and there was no evidence of recurrence.
