Cytochemical identification of T lymphocytes on the basis of alpha-naphthyl acetate esterase (NAE) activity was compared with immunologic markers for cell suspensions and/or cryostat sections of 113 specimens. Nonneoplastic tissues (peripheral blood, lymph nodes, spleens, tonsils, thymus, and pleural fluid) and specimens from various lymphoproliferative disorders, including acute and chronic lymphocytic leukemia, lymphosarcoma cell leukemia, hairy cell leukemia, non-Hodgkin's lymphomas of B-and T-cell types, and Hodgkin's disease, were evaluated. T (E-rosetting) cells demonstrated several patterns of NAE reactivity: 1) a strong globular reaction product, the most specific pattern for T-cell identification, 2) granular cytoplasmic staining, or 3) no reactivity. B lymphocytes revealed a granular pattern of NAE staining, were devoid of enzyme, or, in rare instances, exhibited strong NAE activity. Percentages of lymphoid cells with strong (globular) NAE activity closely paralleled T-cell (E-rosette) values in the majority of cases, with the best correlations observed for peripheral blood studies. However, discordant results were noted for some neoplastic and nonneoplastic tissues, including cases of T-cell lymphoma or leukemia. Markedly discrepant results were noted for thymic lymphocytes, most of which revealed E-rosette formation and weak or absent NAE activity. Lymph nodes involved by Hodgkin's disease demonstrated a heterogeneous pattern of staining in E-rosetting cells and in Reed-Sternberg variants. Cryostat section studies of reactive lymph nodes and nodular lymphomas demonstrated strong NAE staining in lymphoid cells of T-cell (interfollicular, internodular) areas, with little or no positivity in follicles or nodules (B-cell areas). NAE staining patterns further suggested that T cells comprise part of the follicular cuff and possibly represent a minor population of some neoplastic nodules. Although NAE determinations do not represent a consistently reliable alternative to immunologic methods for T-cell identification, this easily applicable cytochemical marker is complementary to other techniques in assessing neoplastic or nonneoplastic tissues, particularly cryostat sections. (Am J Pathol 97:17--42, 1979).

Lymph nodes removed from 28 untreated patients with Hodgkin's disease all contained markedly increased amounts of hemosiderine, whether or not they were histologically involved in the disease. This finding was particularly striking in patients with the nodular sclerosis type of disease. Abnormal deposits of iron were also noted frequently in lymph nodes containing metastatic carcinoma, lymphoma of non-Hodgkin's type, and reactive hyperplasia, but in each case, with the exception of metastatic squamous cell carcinoma, the amount was significantly less than seen in Hodgkin's disease. The findings suggest that in patients with Hodgkin's disease and perhaps in those with other disorders in which abnormal tissue retention of iron underlies sideropenic anemia, lymph nodes are an important site of iron retention.

A 59-year-old man was initially diagnosed as having Hodgkin's disease, nodular sclerosis type, and complete remission was achieved after combination chemotherapy. One year later, he developed a high fever and recurrence of the Hodgkin's disease was diagnosed. Salvage chemotherapy was ineffective, and the patient died. Autopsy specimens showed infiltration of lymphoma cells into multiple organs. Lymph nodes showed characteristics of non-Hodgkin's lymphoma, with expansion of anaplastic large cells; this differed from the histological features at initial diagnosis. Immunohistochemical staining was positive for CD30/Ki-1, but negative for CD15 (LeuM1). These findings were compatible with Ki-1 lymphoma, suggesting that this may be a case of CD30/Ki-1 lymphoma preceded by Hodgkin's disease and that a certain proportion of Ki-1 lymphomas and Hodgkin's disease may share the same cellular origin.

Clinical and morphological findings of lymph nodes in 150 consecutive untreated non-Hodgkin lymphoma (NHL) patients were retrospectively studied. One hundred and fifteen (77%) patients had B-NHL and 35 (23%) T-NHL, 96 (64%) patients had NHL low grade malignancy and 54 (36%) NHL of high grade malignancy according to the Kiel classification. Lymph nodes exceeding 2 cm in diameter (p less than 0.05), hepatomegaly (p less than 0.05), splenomegaly (p less than 0.05), and the duration of lymphadenopathy for more than 6 months preceding diagnosis (p less than 0.01) were significantly more common in low than high grade malignancy of NHL patients. Febrile episodes at the diagnosis were significantly more common in high than in low grade malignancy of NHL patients (p greater than 0.05). Lymph nodes exceeding 2 cm in diameter (p less than 0.05) in B-NHL, and lymph nodes above the diaphragm (p less than 0.05) and skin infiltration (p less than 0.001) were more common in T-NHL than in B-NHL patients. At the diagnosis low grade NHL patients have significantly more often splenomegaly, hepatomegaly, large palpable lymph nodes, and long lasting lymphadenopathy before diagnosis. High grade malignancy NHL patients have more often general symptoms, B-NHL patients have more often large palpable lymph nodes, T-NHL patients have more often skin infiltration and lymph nodes above the diaphragm. Precise clinical characterization of patients in addition to pathohistological diagnosis are very important in this highly variable disease.

Lymph nodes were examined from four patients with incipient adult T-cell leukemia-lymphoma (ATLL) who had mild lymphadenopathy, fatigue, no or a few atypical lymphocytes in their peripheral blood, and integrated proviral human T-cell lymphotrophic virus type I (HTLV-I) DNA in the nodes. The HTLV-I DNA was detected by southern blot analysis and/or polymerase chain reaction in the lymph nodes of all cases. The nodal architecture was preserved. Some scattered or aggregated highly lobular, cerebriform, or Reed-Sternberg-like giant cells were observed, with occasional mitoses and diffuse infiltration of small to medium-sized lymphocytes, with no or minimal nuclear abnormalities in the enlarged paracortex. The giant cells were usually positive for Ki-1 and also for UCHL-1 and other T-cell markers but negative for Ber-H2. Rearrangement and/or deletion of T-cell receptors were found in three of four patients. All patients died within 2 years, with transformation to overt leukemia-lymphoma occurring in three patients, and pulmonary carcinoma in one. The incipient or prelymphomatous phase of ATLL should be differentiated from Hodgkin's disease because of the distinctly different prognoses of these two diseases.

Lymph nodes from patients with acute infectious mononucleosis (AIM) typically show marked paracortical expansion and a prominent immunoblastic proliferation that can occur in nodules and sheets, as well as within sinuses. The marked immunoblastic proliferation, coupled with Reed-Sternberg-like cells and a polymorphous inflammatory cell background, may simulate either non-Hodgkin's lymphoma or Hodgkin's disease. A recently described entity, Ki-1-positive lymphoma, or large cell anaplastic lymphoma, shares some clinicopathologic and phenotypic features with AIM and must be considered in the differential diagnosis. The present case describes a 20-year-old male who had signs and symptoms consistent with AIM, which he was later proven serologically to have, but whose cervical lymph node showed features suspicious for large cell anaplastic lymphoma. In addition, the Ki-1 (CD30) antigen was expressed by some of the atypical immunoblasts, further raising this possibility.

Lymph nodes obtained from 7 HIV-positive and 20 HIV-negative patients with Hodgkin's disease were examined for the presence of Epstein-Barr virus antigens and genome. EBV antigens were observed in only 2 out of 20 HIV-negative patients, whereas lymph nodes of HIV-positive patients did not reveal evidence of EBV antigens. By in situ hybridization and Southern blot analysis, EBV genome was found in 5 out of 7 HIV-positive patients; the EBV genome was detected in the nucleus of Reed-Sternberg and Hodgkin's cells. EBV DNA was observed by in situ hybridization and Southern blot analysis in only 3 out of 20 HIV-negative patients with Hodgkin's disease. In both groups, Reed-Sternberg and Hodgkin's cells were negative for C3d EBV receptor. Our results show a statistically significant increased expression of EBV DNA in HIV-positive patients with Hodgkin's disease, as compared with HIV-negative patients with HD.

Esophageal involvement of non-Hodgkin's lymphomas is extremely unusual; primary lymphoma of the esophagus is even less common. This report describes a case of malignant small lymphocytic-plasmacytoid lymphoma with primary esophageal localization. Endoscopic diagnosis was confirmed by histological examination of a large portion of tumoral tissue spontaneously expelled after esophagogastroscopy. Lymph nodes, bone marrow, and other gastrointestinal sites were not involved in the disease. We describe the clinical history of the patient, with the remissions induced by chemotherapy, over a 5-yr observation up to the patient's death, which was not directly related to the tumor.

Lymph nodes or tumor biopsies of 60 persons suspected of having a malignant lymphoma were examined for the presence of Epstein-Barr virus nuclear antigen (EBNA) by anticomplement immunofluorescence. In 8 cases the tissue specimens were also assayed for Epstein-Barr virus (EBV) DNA by nucleic acid hybridization. Serum samples of patients and controls were tested for EBV-related antibodies. The histological tests in 37 cases showed a malignant non-Hodgkin lymphoma, and in 23 cases a reactive lymphadenopathy. A Burkitt lymphoma of a European boy and a polymorphic centroblastoma contained EBNA and approximately 27 or 30 genome equivalents EBV DNA per cell, respectively. EBNA was also demonstrated in about 20% of the cells of a lymph node from a patient with recurrent reactive lymphadenopathy.
