Pleomorphic Adenoma of the Hard Palate: Case Report

Pleomorphic adenoma (PA), or benign mixed tumor, is the most common salivary neoplasm. Most common intraoral location is the palate (specifically, the junction of the soft and hard palates), followed by upper lip, buccal mucosa, floor of the mouth, tongue, tonsil, pharynx, and retromolar area. They have, as the name suggests, mixed histology which consists of three components: an epithelial, a myoepithelial and a mesenchymal component. PA appears as firm, slowly growing and painless mass, sometimes they have mucosal ulceration as was the case with this patient. The mean age is between 43 and 46 years and there is a slight female predilection. Diagnosis of PA is established according to the physical examination, histopathology and cytology which are supported by radiographic findings of computed tomography (CT) scan and magnetic resonance imaging (MRI). Palatal PA are best treated by wide surgical excision including its surrounding capsule, involving the periosteum and overlying mucosa and followed by curettage of the underlying bone with a sharp instrument or bur to avoid recurrence. We report the case of a 41-year old man who was referred by his general dentist with complaint of a swelling in hard palatal region. The surgical specimen was sent for histopathological analysis and it confirmed to be pleomorphic adenoma.
