Chromosomes in malignant lymphomas (study on short-term lymph node cultures).

In 15 cases, chromosome studies were performed in short-term lymph node cultures, using the banding technique. Clonal aberrations were found in two cases of Hodgkin's disease and in two of lymphosarcoma. In agreement with earlier observations, the cases of lymphosarcoma with abnormal karyotypes proved hyperdiploid. No chromosomal aberrations were found in three cases of reactive lymphoreticular hyperplasia.
