Eight cases of primary gastric lymphomas have been investigated by AgNORs method to individualize the patterns of distribution of NORs. Modifying and exemplifying the scheme of Nikicicz and Norback, previously applied to blood smears and bone marrow in patients affected by leukaemia, the authors found 8 principal distribution patterns of AgNORs. Recording the percentage of the single patterns in every case it was possible to individualize two quite homogeneous groups. The authors maintain that in this way, avoiding complex numerical evaluations and statistical analysis, it is possible to easily classify the gastric lymphomas. We suggest that an improvement of the results could be achieved by comparing the immunophenotype of the cellular lymphomatous populations, and the AgNORs pattern with patients survival.
