Abstract
A 65-year-old white male patient attended a surgical service because of a maladaptation of upper denture. Clinical examination showed white and erythematous lesions in the vestibular alveolar ridge and hard palate, respectively, with a slight volume increase. Tomographic examination showed expansive lesion associated with the destruction of the left hard palate and maxillary sinus. Incisional biopsy was performed in both lesions, and the specimens were referred for anatomopathologic examination with clinical suspicion of epidermoid carcinoma. Histopathologic examination revealed malignant glandular neoplasm characterized by proliferation of sheets and nests of hyperchromatic cells with scarce cytoplasm forming double layer ductile structures containing intraluminal eosinophilic material and solid areas with central necrosis and discrete mitosis figures. The diagnosis of adenoid cystic carcinoma was established. The patient underwent left maxillectomy, and histologic examination of the surgical specimen confirmed the previous diagnosis and pT4 to pNX staging. The patient is undergoing radiotherapy treatment.
