Abstract
Pleomorphic adenoma (PA) is a benign tumor of the salivary glands commonly seen in the parotid and submandibular salivary glands. Rarely, it is seen in the minor salivary glands located at lips, palate, and other parts of the upper aerodigestive tract. We report a case of an unusually large PA of the hard palate in a female patient involving left maxillary sinus and nasal cavity. After excising, the tumor with adequate clinical margins (1 cm), a large postsurgical defect was managed by the use of obturator and it gradually healed by secondary intention in about 6-month period. The unique feature in our case was that in spite of the long duration of the tumor (30 years), it did not undergo malignant transformation.
