A case of malignant lymphoma in maxillary gingiva

Malignant lymphoma is a neoplasm arising from the lymph node and lymphoid tissues. This tumor occurs frequently in the head and neck, but it occurs rarely in the oral cavity. Usually the first symptom of this tumor is painless swelling. A 56-year old man was reffered to the clinic with the chief complaint of severe pain and ulcer formation on the upper jaw gingiva. The specimen from the gingiva indicated malignant lymphoma histologically. The patient received radiotherapy and combination chemotherapy with ACOP. Therapy was not so effective in this case. The patient was dead 6 months after onset. In this report, the clinical course is presented with some comments based on the existing literature.
