Description
Background Most of the lymphomas arising in the oral cavity are of B-cell origin. Among these, diffuse large Bcell lymphomas are the most common. Diffuse large B-cell lymphomas may exhibit more than one chromosomal rearrangement and are then referred to as ‘double-hit’ or ‘triple-hit’ lymphomas. Case report We present a case of an intraoral ‘double-hit’ lymphoma in a 76-year-old male who had been referred by an oral surgeon in private practice. Intraoral examination exhibited a firm, exophytic lesion in the region of the right hard palate and buccal mucosa with extension to the soft palate. Radiographic examination exhibited a massive thickening of the right sinus membrane, and arrosion of the lateral and basal cortical sinus walls in the right maxilla. After diagnosis of the lesion, the patient was treated with six cycles of chemotherapy. Discussion Lymphomas arising within the oral cavity account for less than 5% of all oral malignancies and typically affect the palatine tonsils and the palate. ‘Double-hit’ lymphomas are associated with older age, usually present with an advanced stage of disease, and show an aggressive clinical behaviour. They normally have a poor prognosis, even when treated with intensive chemotherapy regimens. Nevertheless, in the case presented, the patient was free of symptoms 1 year after initial diagnosis.
