Abstract

While cell suspension immunophenotypic studies are widely used as an aid in the diagnosis and classification of lymphomas and leukemias, much less attention has been directed toward interpretation of the results in reactive lymphoid proliferations. Cell suspension immunophenotypic data were therefore analyzed for 119 lymph nodes with reactive lymphoid proliferations which were divided into five major histologic categories: follicular hyperplasia, marked (FH,M), or moderate (FH); dermatopathic lymphadenopathy (DL); diffuse hyperplasia (DH); or "other." With the aid of a computer-assisted morphometer, the following were also measured and calculated: proportion of node occupied by follicles, mean relative follicle size, and mean follicle shape factor. Finally, in 57 cases, the influence of human immunodeficiency (HIV) status on the findings was analyzed. Although individual cases varied widely, cases of DL had significantly more CD3+ (T) cells, higher CD4:CD8 ratios, and fewer CD19+ (B) cells than other categories. Cases of FH,M had significantly lower CD4:CD8 ratios and more CD19+, CD10+, and transferrin receptor positive cells. Cases of FH,M and FH known to be HIV-negative had higher CD4:CD8 ratios than the HIV-positive cases. P...Continue Reading
