Clinico-anatomical features of two diseases distinguished recently from the large group of long-known lymphoproliferative diseases: Lennert's lymphoma designated also as lymphogranulomatosis X and angioimmunoblastic lymphadenopathy, are described. Typical morphological features and clinical signs of each diseases are presented and similarity of many of them is noted which gives ground to consider some cases of angioimmunoblastic lymphadenopathy and its variant, immunoblastic lymphadenopathy to be equivalents of some observations classified as Lennert's lymphoma. Frequent malignization of the processes and their transformation into immunoblastic lymphoma is noted especially. Further ways for the study of this problem are outlined and the main approaches for differential diagnosis of the described nosological forms, Hodgkin's disease and non-Hodgkin's lymphomas are indicated. |
