Biclonal trisomy 3 in a case of epithelioid cellular lymphogranulomatosis (Lennert's lymphoma).
Biclonal trisomy 3 in a case of epithelioid cellular lymphogranulomatosis (Lennert's lymphoma) was demonstrated by Q-banding polymorphisms of chromosome #3. Seventeen of 19 mitoses with trisomy 3 showed duplication of 1 of the homologous chromosomes and the remaining 2 showed duplication of the other chromosome. It is assumed that both chromosomes #3 independently underwent nondisjunction and that this led to the development of the two abnormal clones. Moreover, there appeared to be a qualitative difference between the two clones, because one of them made up a major proportion and the other a minor proportion of the cells in both of the two samples studied at different times.
