A 65-year-old woman was referred for the evaluation of a large mass on the right maxilla, which rapidly grew after tooth extraction in this region. Intraoral examination revealed an extensive well-defined nodular lesion located in the maxillary alveolar process, expanding both vestibular and palatal cortices, covered by normal oral mucosa pervaded by telangiectasia, of fibrous consistency, and asymptomatic. Panoramic x-ray did not present marked bone involvement, and an incisional biopsy was performed with the clinical hypothesis of maxillary sinus carcinoma and salivary gland malignant tumors. Histologic analysis showed neoplastic infiltration with lymphoid differentiation, and the final diagnosis was diffuse large B-cell lymphoma. The patient was referred to the oncologist and started a chemotherapy protocol with a remarkable reduction of the lesion after the first month of treatment with low adverse effects. Lymphomas of the oral cavity are rare, representing only 3.5% of the cases reported in the literature.
