[Pathomorphology and clinico-pathology of Lennert lymphoma].

31 cases of malignant lymphoma classified earlier in the Malignant Lymphoma Reference Center as Lennert lymphomas (LL) have been reinvestigated. In 14 cases out of the 31 presence of a small number of Sternberg-Reed (SR) cells has been revealed and the diagnosis of Hodgkin disease (Hk) was made. 4 cases proved to be angioimmunoblastic lymphomas. In 2 cases out of 13 LL-s micro-SR-cells have been found and in one of these cases later Hk disease has developed. In the further 4 cases in the first biopsies polynucleated lymphocytes and giant cells of non -SR-type have been noticed. In this patients later on malignant lymphomas of T-cell type have developed.
