Pleomorphic Adenoma of Hard Palate: A Case Report and Review of Literature.

ABSTRACT

Pleomorphic adenoma is a benign mixed tumor, which is composed of myoepithelial and epithelial cells. A fibrous capsule separates these cells from the surrounding tissues. Pleomorphic adenoma has unusual histopathologic features. It is the most common benign tumor affecting both major and minor salivary glands. Parotid salivary gland is affected mostly in the major group, and palate is the most common site affected in minor salivary glands. The upper lip is the second most common site followed by buccal mucosa. Less than 3% of the salivary gland tumors account for head and neck tumors. In few cases, benign pleomorphic adenoma may turn malignant also. In this case report, a female patient aged 32 years who reported with a complaint of painless swelling in the palate is presented.
