The transition between atypical hyperplasia and lymphoma with angioimmunoblastic lymphadenopathy and dysproteinaemia (AILD) was studied in serial lymph node biopsy specimens from five patients using DNA analysis with Southern blot analysis, polymerase chain reaction, chromosomal analysis, and immunophenotyping. The chromosomal analysis showed additional abnormalities as the disease progressed to those present initially, and immunological staining showed a corresponding increase in the numbers of CD4- and Ki67-positive cells. In the first biopsy from each patient a diagnosis of atypical hyperplasia with AILD was made and lymphoma excluding by the finding of only a few atypical lymphoid cells and the preservation of follicles with germinal centres. DNA analysis of lymph nodes at this stage showed either germ lines or oligoclonal rearrangements of the T-cell receptor (TCR) and immunoglobulin heavy chain genes. In the final biopsy, when a diagnosis of lymphoma with AILD was made, either a monoclonal rearrangement of the TCR was observed or one of the rearranged bands had increased in density. These results suggest selective proliferation of a clone of abnormal cells may account for the progression of atypical hyperplasia to lymphoma with AILD.
