Cytologic diagnosis of malignant lymphoma can be extremely difficult because the cytologic features of the malignant cells in small cell and mixed small and large cell lymphomas may be indistinguishable from those of reactive lymphoid cells. In addition, large cell lymphoma can be difficult to distinguish from undifferentiated carcinoma in cytologic specimens. Using the avidin-biotin immunoperoxidase technique and antibodies to the B cell markers .alpha., .gamma. and .mu. H chains and .kappa. and .lambda. L chains, to the T cell markers Leu-1, Leu-2a and Leu-3a, to the lymphoid marker T200, to TdT [terminal deoxynucleotidyl transferase] and to Leu-M3, were used to study 35 cytologic specimens including pleural, cerebrospinal, and ascites fluids and fine-needle aspirations. Immunologic staining allowed them to make a definitive diagnosis of lymphoma or reactive effusion in every case studied and resulted in a significant modification of the morphologic diagnosis in over 50% of cases. In 16 cases the lymphoid cells were monoclonal B cells: 10 expressing IgM .kappa.; 4 expressing IgM .lambda.; 1 expressing IgA .kappa.; and 1 expressing .kappa. without demonstrable H chain expression. Although there are no good markers of nonoclonality for T cells, a positive diagnosis was made in 2 cases of T cell lymphoid malignancies by the expression of an aberrant phenotype on the malignant cells. The expression of TdT confirmed the diagnosis in 1 case of common ALL [acute lymphoblastic leukemia] and 1 lymphoblastic lymphoma. In a patient with a null cell large cell lymphoma, the expression of T200 on the malignant cells ruled out the possibility of carcinoma. In 15 cases the marker studies indicated a reactive lymphoid proliferation. Immunologic markers are apparently very useful in the cytologic diagnosis of lymphoma.
