Pleomorphic adenoma, considered the most frequent benign mixed neoplasm of the minor salivary glands, occurs mainly in the region of the hard palate, with slight predilection in females and peak of incidence between the third and fifth decades of life. An increase in recurrence rates has been associated with the histopathological variants of the tumor, cellular characteristics, stroma, and capsule rupture during surgical removal of the lesion. The present case report aims to describe the surgical approach performed on the patient, a 45-year-old woman with a recurrent Pleomorphic Adenoma (PA) in the region of the hard palate on the right side, 10 years after initial enucleation of the lesion; her main complaint was an increase in volume in the palatal region. After extensive local surgical excision of the tumor and 2 years of follow-up, there were no signs of recurrence. Computed tomography and a correct histopathological diagnosis are essential to enable the establishment of an appropriate surgical treatment, with the purpose of achieving complete removal of the lesion, with wide surgical margins, including the lining mucosa and the underlying periosteum, as described in the present case.
