We studied 11 cases of malignant lymphoma diagnosed concurrently with or following lymph node infarction. Cases included seven B-cell lymphomas, three T-cell lymphomas, and one case of Hodgkin's disease. Sections of viable and infarcted tissue were immunostained in parallel using a panel of antibodies effective in routinely processed, wax-embedded tissue. The panel included anti-leucocyte-common antigen (CD45), T-cell-associated antigens (UCHL1, MT1), B-cell-associated antigens (MB1, 4KB5 (CD45R), MT2, LN1), a B-cell-specific antigen (L26), C3D-1 (CD15), and BER-H2 (CD30). Antibodies to intermediate filament cytoskeletal proteins, epithelial membrane antigen, and Factor VIII-related antigen were also used. In eight cases, staining of the infarcted material gave evidence of a lymphoid proliferation of either T- or B-cell type; an in the case of Hodgkin's disease, the results supported this diagnosis. The immunophenotype derived in the infarcted tissue mirrored the findings in the viable material in these eight cases of non-Hodgkin's lymphoma. A case of testicular infarction with concurrent intraosseous lymphoma was also examined. Staining in this case provided evidence of infarcted lymphoma. Thus, immunostaining of infarcted lymphoid tissue with these novel antibodies provides valuable information that conventional light microscopy cannot offer.

High grade malignant non-Hodgkin's lymphoma (NHL) was the presenting manifestation of the acquired immunodeficiency syndrome (AIDS) in 3/81 reported cases of AIDS in Denmark (by April 2, 1986). Asymptomatic HIV infection, 1 and 5 yr prior to the onset of lymphoma, was documented in 2 cases. 1 patient became infected by Factor VIII treatment, 2 were male homosexuals. 2 patients had an uncommon tumour presentation in the oral cavity, 1 patient presented with an abdominal mass. The histologic subtypes were immunoblastic (2), and small noncleaved cell, Burkitt's (1). Helper/suppressor T-cell ratio was decreased at onset of lymphoma in 2 cases. All 3 patients have died, 4, 6, and 24 months after diagnosis of NHL. Only 1 patient died of NHL, 1 died of an unclassified pneumonia and the third developed progressing supranuclear HIV-associated polyneuropathy without evidence of CNS lymphoma. Thus, high grade malignant B-cell NHL is a regular initial manifestation of AIDS, and may develop after years of asymptomatic HIV infection.

Levels of copper, haptoglobin, fibrinogen and Factor VIII were measured in 30 patients with non-Hodgkin's lymphoma on 90 occasions in an attempt to demonstrate a possible correlation between hypercupremia and other acute phase reactants. The four parameters were measured simultaneously in active disease and in remission. The serum copper, along with other parameters, was significantly elevated in the active disease (P less than 0.001) and there was a high correlation between the levels of serum copper, fibrinogen and haptoglobin (P less than 0.001).

Angiogenesis has a major role in the pathogenesis of malignancies. Studies involving the role of angiogenesis have been most commonly performed in solid tumors. However, studies related to hemapoietic neoplasia and angiogenesis are relatively limited. We investigated the role of angiogenesis in non-Hodgkin's lymphomas (NHLs) and its relation with clinical and histopathologic prognostic indicators. In this respect, angiogenesis markers were evaluated in 71 patients with NHL and these were compared with other prognostic indicators including age, gender, histological grade, stage, extranodal involvement and survival. Microvessel density (MVD) using Factor VIII monoclonal antibody and vascular endothelial growth factor (VEGF) using monoclonal antibody for VEGF expression were studied in paraffin-embedded tissue samples. We did not find a significant relationship between MVD and patient characteristics including age, gender, stage, histological grade, nodal status, international prognostic index (IPI), and response to treatment. MVD was found to be greater in cases with B symptoms compared to those without B symptoms (14.6 +/- 5.7 and 11.4 +/- 5.3, respectively, p = 0.002). No significant relationship was found between VEGF and age, gender, stage, histological grade, IPI, and overall survival. The complete and partial response rate to therapy was significantly higher in VEGF-negative patients than in the VEGF-positive patients (p = 0.003). In conclusion, there appears to be a role for angiogenesis and angiogenic factors in NHLs. The combination of anti-angiogenic drugs with conventional anti-neoplastic treatment will probably be used in the future. Larger series of patients are needed to determine the prognostic value of angiogenesis in NHL.
