Abstract
A 58-year-old female patient was referred because of a palatal nodular lesion. The patient reported that the lesion began 4 years ago, and she was attended by 5 different dentists without definitive diagnosis. Given its exacerbated growth in the last months, she sought care again, and then she was referred to our center. Clinical oral examination revealed an extensive nodular lesion located on the hard palate measuring 4 × 3 cm with well-defined limits, smooth surface, and pain with palpation. Our diagnostic hypotheses were pleomorphic adenoma and adenoid cystic carcinoma (ACC). Incisional biopsy was performed, and based on histopathologic and immunohistochemical findings, the diagnosis of ACC was established. Partial maxillectomy and rehabilitation with maxillary obturator prosthesis were performed. Currently, the patient is undergoing dental and psychological care in our center.
