Out of a total of 48 patients with malignant lymphomas of the maxillofacial area, only 2 patients had been referred with a correct tentative diagnosis within a period of 11 years. In 83% the main symptom was painless swelling of the affected structures. Almost 50% of the extranodal manifestations were found in the mouth.
