    Notes: This paper describes the histological picture of four tumours of the follicular compartment of the lymph node, in which the proliferating cell appeared to be the dendritic reticulum cell (DRC). This assumption was based on the results of light microscopical, ultrastructural, immunological, and enzymehistochemical investigations. The tumour cells resembled DRC's closely in (1) the striking pattern of interdigitations and occasional tight junction-like contacts between the neo-plastic cells on electron microscopical analysis; (2) presence of receptors for the activated third component of complement on the membrane of the cells; (3) absence of monoclonal immunoglobulins and T-cell antigen on the surface and of lysozyme, α1-antitrypsin or α1-antichymotrypsin in the cytoplasm of the neo-plastic cells. Moreover, (4) the tumour cells showed moderate α-naphtyl acetate esterase, weak to absent acid phosphatase and (with one exception) strong 5-nucleotidase activity. Furthermore, (5) the neoplastic cells expressed la-like antigens on the surface in all four cases. The relation with follicle centre cell lymphomas, the differential diagnosis and clinical data are discussed.

    Notes: One hundred and nineteen methacrylate-embedded trephine biopsy specimens from 80 patients with Hodgkin's disease are reviewed. Although marrow involvement was found in 4% of the untreated patients, the present study was mainly concerned with the marrow unaffected by specific infiltrates and in negative specimens. The non-involved bone marrow in Hodgkin's disease invariably showed alterations of three types; stromal damage, inflammatory infiltration, and disturbed haematopoiesis. Each of these features can be found in the absence of one or both of the others. In severe examples, all three of these components usually occur simultaneously, giving histological pictures that mimic Hodgkinspecific infiltrates, sometimes in association with clinical suggestions of bone marrow involvement or replacement. But trephine biopsies of sufficiently high histological quality offer alternative explanations for the pancytopenia, for instance intramedullary phagocytosis, reactive sclerosing inflammation resembling auto-immune disorders, or a disturbance of haematopoiesis itself. This disturbance could be due to a defect inherent in the haematopoiesis associated with Hodgkin's disease, possibly predisposing for leukaemia in longterm survivors who have received chemotherapy and/or irradiation. The disturbed erythropoiesis proved to be strongly correlated with the stage of the disease at the time of biopsy. This finding could contribute to staging procedures, when laparotomy is contraindicated.

    Notes: Summary We compared three consolidation regimens in patients with acute myelogenous leukemia in first remission. Thirty-four patients received only intensive consolidation chemotherapy (SIC); 28 patients were scheduled to undergo an autologous bone marrow transplant (auto-BMT) and 44 patients an allogeneic BMT (allo-BMT). Twenty-seven of them were referred in first remission for allo-BMT. Nineteen patients achieved a complete remission after salvage treatment. All other patients obtained a remission after one or two courses of a standard combination of cytosine arabinoside and daunorubicin. Except for the patients who were referred in remission, all patients received intermediate dose cytosine arabinoside and amsacrine as a first consolidation treatment. The median ages of the three groups were 48 (SIC), 39 (auto-BMT) and 33 years (allo-BMT). Two patients relapsed before auto-BMT and 1 before allo-BMT. The median interval from the date of complete remission to the auto- or allo-BMT was 3 months. In total, 80% of the patients of the SIC group relapsed, compared to 50% of the patients belonging to the auto-BMT group and 35% of the 44 patients who were scheduled to receive an allo-BMT. The overall median disease-free survival was 14 months, 30% of the patients being alive and disease-free at 3 years. The disease-free survival rate at three years was 25% for the SIC group, 30% for the allo-BMT group and 40% for the ABMT group (P=0.45). Our study shows no benefit for bone marrow transplantation over intensive consolidation treatment. However, large randomized trials are required to define the real value of these treatment modalities.

    Notes: Abstract  Thirty-two patients with untreated ALL (n=26) or lymphoblastic lymphoma (n=6) between 17 and 65 years of age were treated with a short remission induction course with VP16-213, amsacrine, intermediate dose Ara-C for 6 days, prednisone and intrathecal methotrexate, followed by a consolidation course with vincristine, amsacrine, high dose Ara-C for 4 days, prednisone and intrathecal methotrexate. After subsequent cranial irradiation, no further maintenance was planned. However, some patients underwent an allogeneic (n=5) or autologous (n=5) bone marrow transplantation after the consolidation treatment. Twenty-three of 32 patients (72%) achieved a complete remission. Ten of 13 patients with T-ALL or lymphoma, six of eight patients with pre-B or common ALL, and seven of 11 patients with B-ALL or Burkitt's lymphoma achieved a complete remission. The median duration of remission was 24 months. Overall survival for the whole group was 35% at 5 years. The disease-free survival was 45% at 5 years. Long-term survival for patients with B or T-ALL was approximately 60%, compared with 15% for those with common or pre B-ALL. Short term intensive courses including intermediate or high dose Ara-C during remission and consolidation treatment lead to results comparable to those obtained with long-term maintenance regimens. Our regimen may be sufficient for patients with T or B-ALL. Larger randomized studies are needed to investigate the relative importance of our observations.

    Notes: Abstract We present a patient with chronic myelomonocytic leukemia who showed disseminated papules and nodules. Arguments in favor of leukemia cutis are the clinical appearance, the cyclic pattern with which the lesions appeared and disappeared, and the histologic features. The lesions reproducibly responded to treatment with antibiotics given for a Staphylococcus aureus infection. We speculate that at least in some patients, leukemic cells are recruited in the skin because of local infection and do not merely reflect autonomous growth but an inflammatory response.

    Notes: Abstract We report the case of a 60-year-old man with febris of unknown origin, severe pancytopenia, and rapidly developing splenomegaly due to reactive hemophagocytic syndrome and Hodgkin's disease. Reactive hemophagocytic syndrome is often rapidly fatal and, once this diagnosis is considered, an underlying infection or malignancy should be treated promptly. An extensive search of the literature revealed only two other cases of reactive hemophagocytic syndrome and Hodgkin's disease. This is the only reported patient who survived after being diagnosed as having reactive hemophagocytic syndrome and Hodgkin's disease.
