Introduction: The pleomorphic adenoma, a benign neoplasm, is one of the most common pathologies of the salivary gland. The treatment of choice for pleomorphic adenoma is surgical excision. The aim of this study is to report a case of a large pleomorphic adenoma located in accessory salivary gland in the hard palate region. Case report: A 22-year-old female patient was referred from her primary health unit due to an asymptomatic lesion located in the hard palate with a 1-year evolution. The intra-oral examination revealed an extensive nodule on the right side of the palate. The examination of the incisional biopsy revealed the histopathological diagnosis of pleomorphic adenoma. The patient underwent surgical excision, under general anesthesia, presenting a good postoperative evolution, without signs of recurrence. Discussion: The diagnosis of pleomorphic adenoma is a combination of the clinical aspects with the anatomopathological examination. Although it is a slow growing lesion, when treatment is not early performed, it may reach large dimensions, leading to an increased morbidity of the surgical procedure and to higher rates of recurrence and/or malignant transformation. Conclusion: We emphasize the importance of accurate diagnosis and effective treatment at the earliest possible time. When possible, acrylic intraoral prostheses/obturators may be used in association with surgical approaches, restoring function and increasing the comfort of the postoperative period.
