Abstract

The Pleomorphic Adenoma is the most frequent benign tumor of the salivary glands. The cheeks, lips and gingiva are rare sites of appearance. The objective of this study is to report a case of a Pleomorphic Adenoma arising from the buccal mucosa. A 57-year-old female patient who presented with an increase in volume in the right facial region with one year of evolution, asymptomatic and without treatment. Physical examination revealed a nodular lesion of approximately 3 cm in diameter, located in the right cheek. MRI revealed a hyperintense image in STIR sequence. Excisional biopsy of the lesion was made under balanced general anesthesia, where extracapsular dissection of the tumor was performed, using a transoral approach. The histopathological study resulted in pleomorphic adenoma. Despite the low rate of recurrence of this neoplasm, short, medium and long term follow-ups are recommended.
