[Non-Hodgkin's malignant lymphoma of the oral cavity and Waldeyer's ring--clinico-pathological Studies of biopsy cases].
Forty-five patients with stage IE and IIE malignant lymphoma originating from the oral cavity (23 cases) and Waldeyer's ring (22 cases) were histopathologically studied and their prognoses were assessed. Histologically, 42 cases were identified as diffuse lymphoma. The histiocytic (large cell) type was the prevailing type. The incidence of undifferentiated (large cell) type was relatively high and a few pleomorphic type and Burkitt type lymphomas were found in the oral cavity. The 5-year survival rate was 17% for the oral cavity and 50% for Waldeyer's ring. The survival rate of patients with stage IE malignant lymphomas of Waldeyer's ring was better than that of patients with stage IIE malignant lymphomas of Waldeyer's ring and stage IE X IIE oral malignant lymphomas.
