The most common histopathology in sinonasal region malignancies is squamous cell carcinoma. Salivary gland tumors and lymphomas located in this region are extremely rare. In this article, three rare cases of malignancy affecting the palatomaxillary region are presented. These are non-Hodgkin lymphoma, adenoid cystic carcinoma and pleomorphic adenoma ex carcinoma cases. Radiologic imaging methods, diagnostic workups and treatment methods were discussed. Destructive lesions are seen in the computed tomography and magnetic resonance imaging in all the cases. Chemotherapy and radiotherapy were performed as a primary treatment for sinonasal lymphoma case. Surgical approach was the first treatment option for adenoid cystic carcinoma and pleomorphic adenoma ex carcinoma cases. Even if pre-operative punch biopsies yield benign results, the possibility of malignancy should be considered in large destructive lesions of this region. Postoperative radiotherapy and/or chemotherapy treatment may be required due to the anatomical difficulties of the region.
