Pleomorphic adenoma is the most frequently occurring benign tumor of the salivary glands, composed of both epithelial and mesenchymal tissue elements. In 1972, the World Health Organization (WHO) described it as a well-circumscribed neoplasm exhibiting a diverse or mixed histological appearance. Histologically, the tumor features a combination of identifiable epithelial structures along with mucoid, myxoid, and chondroid stromal components. It predominantly affects the parotid and submandibular glands but can also arise from the minor salivary glands”, often presenting as a painless intraoral mass, typically on the palate or lip. Although it is benign, pleomorphic adenoma carries a risk of malignant transformation estimated at around 9% and is known for its high recurrence potential. This case report highlights the clinical features, imaging findings, and histopathological characteristics of pleomorphic adenoma.
