Pleomorphic adenoma (PA) is a benign epithelial tumor arising from the major salivary glands. Only 6.4% occur in minor salivary glands. Among minor salivary glands, palate is considered as the most common intraoral site, followed by cheek and very rarely in upper lip. Clinically, the lesion occurs as a painless, slow-growing, dome-shaped mass with a smooth surface. The microscopic examination shows a mixture of glandular epithelial and myoepithelial cells within a mesenchyme-like background. The treatment consists of surgical excision down to the underlying periosteum. This case report describes a rare and unusual lesion found in a 12-year-old male patient, which was diagnosed as PA of the minor salivary gland in the upper lip
