Removal of a Massive Pleomorphic Adenoma on the Palate Using Subtotal Maxillectomy: A Report of a Rare Case and Literature Review

Pleomorphic adenoma is the most prevalent salivary tumor, 65% of which occur in major glands. This tumor varies in terms of size depending on the gland where it is located. The most common sites of the minor salivary glands are the palate, lips, cheeks, and throat. Palatal pleomorphic adenoma is laterally located, rarely crossing the midline. This tumor is painless with slow growth rate, which often appears in the fourth or fifth decade of life with female predominance. The tumor may enlarge with delayed treatment. This study aimed to present the case of a 51-year-old woman with an oversized mass on the palate (diameters: 8.5x5.5x2.5 cm), which extended from the anterior portion of the hard palate to the soft palate with a slow growth rate within 10 years. The case definition was accompanied by the determined surgical treatment.
