Lennert's lymphoma

Four cases (3 M, 1 F) of Lennert's lymphoma were presented. The age (38-76 years), the clinical aspect and the morphopathological features were characteristic. Despite an intensive chemotherapy, 3 of the 4 patients died between 2 and 16 months (mean survival time 7 months). The controversies about the nosological delimitation and the cellular nature of Lennert's lymphoma are presented. Because of the poor prognosis, it should be considered as a high-grade malignant non-Hodgkin lymphoma.
