Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes. As the number of abnormal cells increase in a lymph node, the size of the lymph node increases.
