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.
