Abstract
Pleomorphic adenoma (PA) most commonly affects the major salivary glands but can also involve the minor salivary glands, particularly those of the hard and soft palate. However, the current study aims to present a case of upper lip PA. A 29-year-old male presented with a painless, firm, slow-growing swelling (1.5 × 1.5 cm) on the left upper lip. Ultrasonography showed a solid, hypoechoic nodule with irregular margins and mild peripheral vascularity. The encapsulated tumor was excised, and histopathology confirmed PA. At the 7-month follow-up, no evidence of recurrence was observed. Though typically seen in adults aged 40-70, PA can affect younger patients. Complete excision with clear margins is essential due to the risk of recurrence or malignant transformation. PA should be considered in the differential diagnosis of upper lip swellings.
