    Abstract:
    In this study, we analyze histological types of 77 cases H.D. and examine immunohistochemically the reactive cells surrounding Reed-Sternberg cells (40 cases). On the current techniques sections of lymph nodes were def ned H.D. types after the new criteria (Bennett & col., 1985, Buttler, 1992). Immunologic marker studies were performed on paraffin sections of H.D. tissue utilizing the avidin--biotin peroxidase complex technique with limited panel of monoclonal antibodies OKT3, OKB1, OKM1. On histopathologic grounds we established the diagnosis of lymphocytic predominance type in 6 cases--8%, nodular sclerosis type in 36 cases--47%, from which first degree--24 cases and second degree--12 cases, mixed cellularity type in 28 cases--36% and lymphocytic depletion type in 7 cases--9%. Immunohistochemically, in our 40 H.D. cases, the number of T. lymphocytes in all H.D. types, was highly variable, ranging from a minority to a vast majority of cells directly surrounding the Reed-Sternberg cells. These lymphocytes were positive for OKT3, which were more in tissue involved by nodular sclerosis or mixed cellularity types than in the lymphocytic predominance type. Thus, in our few cases of lymphocytic predominance type, the reactive proliferation was consisted of B. cells along side with a few T cells. Also the OKM1 positive mononuclear cells were few. In conclusion, our data support the necessity to extend of several immunohistochemical investigations used for distinguishing H.D. disease from benign hyperplasia and from non-lymphoid malignancies, and for concerning the functional lymphocytic composition and the role of monocyte-macrophage system in the immunological alteration in H.D.
