Some immunological peculiarities in generalized plasmacytoma and their possible clinical interpretation

According to the immunological classification, plasmacytoma is assigned to the group of secretory immunocytomas. The designation "immunoproliferative hemoblastosis" implies certain peculiarities of immunological reactivity in its malignant transformation. The study deals with some of the more recent concepts on the immunochemical properties and morphological differentiation of plasmatic or plasmacytoma cells. Mention is also made of the results of some tests for evaluation of the function of T and B lymphocytes in patients suffering from a generalized plasmacytoma, during the course of chemotherapy.
