Clinical and pathological features of non-Hodgkin's lymphoma of the tonsil. Review of the literature and report of 10 cases.

Ten patients with tonsillar lymphomas diagnosed and treated in our hematology unit from 1979 to 1986 are reported. The heterogeneous histology at presentation, the aggressiveness of the histologic types during relapse, and the relatively low incidence of gastrointestinal tract involvement are discussed. A review of the literature is presented. In view of the better survival rate obtained with chemotherapy or combined chemo- and radiotherapy, we confirm that lymphomas of the tonsil should be aggressively treated, regardless of the staging. Among our 10 cases, 2 are of special interest since they progressed into highly malignant disorders: B-acute lymphoblastic leukemia and Burkitt's lymphoma.
