[Initial diagnosis of malignant lymphomas with manifestations in the mouth cavity and adjacent tissues].

The present study investigates a series of 89 lymphomas of the head and neck seen over a 40-year period. The lymphomas were classified according to the Kielclassifikation and staged using the Ann Arbor system. A total of 78 patients had a non-Hodgkin's lymphoma, 50 high grade and 28 low grade. Eleven patients had Hodgkin's disease. Fifty-seven cases were extra-nodal and 52 nodal; 20 were combined. The 5-year survival with Hodgkin's disease was 52.2%, with non-Hodgkin's disease, 66.5%. Low- and high-grade lymphomas had the same 5-year survival (P = NS). Stages I and II had a better prognosis than stages III and IV (P = 0.3).
