We present the clinical and immunological features of a rare case of chronic lymphoid leukaemia with lymphoplasmacytoid morphology. The patient was first admitted suffering from weakness, pallor, dyspnoea, marked splenomegaly, hepatomegaly and systemic lymphadenopathy and panhypogammaglobulinaemia. White blood cell count revealed important leukocytosis (220 x 10(9) WBC/l) with 2% neutrophils and 98% lymphoid cells showing lymphoplasmacytoid features, while lymphoid cells of identical morphology severely infiltrated the bone marrow and lymph nodes. The disease, initially controlled by non aggressive chemotherapy over a period of 30 months, later evolved to a clinical and haematological picture suggestive of Richter's syndrome. Immunophenotyping of the leukaemic cells demonstrated a monoclonal expansion of B-cells bearing surface markers of typical CLL (CD5, CD19, CD20, CD21, CD22, CD23, CD24, CD40 and low density IgM+IgD/kappa) and also the CD11c and CD38 antigens. A proportion of these cells expressed activation markers (CD25, CD69 and CD71). Following in vitro activation with TPA or PWM, the cells responded by weak incorporation of 3H-TdR but failed to secrete immunoglobulins. These findings confirm the broad morphological, phenotypical and clinical spectrum of chronic lymphoid leukaemias.

A 5-year-old girl was diagnosed as having idiopathic thrombocytopenic purpura (ITP) based on symptoms of nasal bleeding and purpura. The platelet count was 35,000/microliters without anemia or leukopenia. Micromegakaryocytes were observed in normocellular bone marrow without dyserythropoiesis or dysgranulopoiesis. She had periosteal fibroma of the rib and atopic dermatitis with elevated serum IgE. Prednisolone and azathioprine were administered but with no response. The cumulative dose of azathioprine was 20 g for 28 months. Nine years after the diagnosis of ITP, she was admitted because of dyspnea and anemia. The white cell count was 26,900/microliters with 17% monocytes. The hemoglobin was 3.9 g/dl and the platelet count was 9,000/microliters. Dyserythropoiesis, dysgranulopoiesis and micromegakaryocytes were observed in hypercellular bone marrow. The chromosome analysis demonstrated 47, XX, +21. She was diagnosed as having chronic myelomonocytic leukemia (CMMoL) and received bone marrow transplantation (BMT) from an HLA-identical sibling conditioned with high-dose busulfan and melphalan. After 17 months of remission, the disease recurred with an abnormal karyotype of 47, XX, +21, 7q+. Despite a second BMT conditioned with high-dose etoposide, cyclophosphamide and total body irradiation, she died of the disease. Refractory thrombocytopenia as a subgroup of myelodysplastic syndrome, rather than ITP, might have preceded the development of CMMoL, with the possibility of azathioprine-induced leukemia.

A 19-year-old man with acute lymphoblastic leukaemia developed fever, general deterioration and somnolence 3 days after a cycle of cytostatic treatment. He had anaemia (haemoglobin 6.6 g/dl), leukopenia (100/microliters) and thrombocytopenia (7,000/microliters). As an acute septicaemia was suspected he received broad spectrum antibiotic therapy, together with two units of red cell and platelet concentrates. However, his condition worsened rapidly over the next 5 hours (meningism, seizures, fever to 41.1 degrees C, dyspnoea). Another blood count revealed severe haemolysis. Computed tomography of the skull demonstrated multilocular intraparenchymal gas formation. Although the antibiotic treatment was extended the patient died several hours later. Retrospective examination for suspected transfusion mismatch provided no evidence for erythrocyte incompatibility. But there was liberation of T-antigen as sign of a bacterial cause of erythrocyte damage. An anaerobic blood culture grew Clostridium perfringens. This case demonstrates that acute intravascular haemolysis in septicaemia should be considered in the differential diagnosis of transfusion mismatch.

A 41-year-old woman was hospitalized because of dyspnoea, myalgia-like aches in the shoulders and back, recurrent fever up to 38 degrees C and a feeling of being in poor health for some 6 weeks. She had allergic rhinitis and, for the past 3 years, bronchial asthma. One year ago maxillary sinusitis had been diagnosed. The blood sedimentation rate was increased and there was marked eosinophilia (74% eosinophils in the differential blood count). The titres of antibodies against cytoplasmatic components of neutrophil granulocytes (pANCA and cANCA) were negative. The chest radiograph showed marked pleuropulmonary shadows. Pulmonary aspergillosis, Wegener granulomatosis, panarteritis nodosa and hypereosinophilic leukaemia were excluded on clinical and biochemical grounds, as well as by bone-marrow biopsy. Transbronchially obtained lung tissue histologically demonstrated interstitial and intra-alveolar infiltration with eosinophilic granulocytes and confirmed the clinically suspected diagnosis of Churg-Strauss syndrome. Under treatment with prednisone, 100 mg daily, the symptoms improved within a few days and the chest radiograph became normal within 14 days. 15 months later the patient, now on prednisone by mouth, 5 mg daily, was free of symptoms.

A patient with an intermediate grade B-cell non-Hodgkin's lymphoma who presented with severe dyspnea caused by lymphoma-related lactic acidosis is described. The serum lactate and pyruvate levels paralleled the disease activity. Although oncologists are familiar with the relationship between bulky solid tumors and lactic acidosis, well-documented lymphoma cases are extremely rare.

Five episodes of fungemias are described; all had occurred in children with leukemia or lymphoma between January 1, 1978 and December 31, 1990. These fungemias comprised 3.4% of the total septicemias encountered during that period. Three episodes occurred during the induction phase and two during relapse. All patients had fever of varying degree and duration. In addition to steroids, all were receiving combination antibiotics before the fungemia had occurred. All patients had severe neutropenia lasting more than one week. Bacteremia preceded fungemia in four patients. Two episodes were diagnosed antemortem. The same species were isolated from other sites in three cases. Fever, chills and gastrointestinal symptoms were the most common clinical features; other symptoms included cough, dyspnea, oliguria and azotemia. One patient experienced skin lesion, dysphagia, hoarseness and hemiparesis. Only one patient survived. The prognosis from fungemia in leukemia and lymphoma patients is very poor. Empiric antifungal therapy is indicated in neutropenic patients who have recurrent or persistent fever despite one week of broad spectrum antibiotics. Early diagnosis and treatment will aid in improving the overall poor outcome of this disease.

A 46-year-old woman with acute promyelocytic leukemia (APL) was treated with all-trans retinoic acid (ATRA) and chemotherapy according to the AML-92, M3 regimen of the Japan Adult Leukemia Study Group (JALSG). Between days 7 and 18 of therapy, she suffered chest discomfort, fever, cough, dyspnea and general fatigue. A chest roentogenogram showed bilateral interstitial infiltrates. Her leukocyte count began to increase rapidly to 6,400/microliters on day 14. Marked hypoxia (PO2 35.9 mmHg) suggested occurrence of retinoic acid (RA) syndrome. She underwent endotracheal intubation and mechanical ventilation with administration of methyl-prednisolone (m-PSL) pulse therapy. Her symptoms promptly abated. Therapy with ATRA was continued and her leukocyte count reached 44,800/microliters on day 19 of therapy. She achieved complete remission on day 48.

High cardiac output failure/state (HCOF) is regular feature of some illnesses e.g. thiamine deficiency, hyperthyroidism, severe anemia, Paget's disease or arteriovenous fistulae. HCOF in multiple myeloma is reported quite rarely. 31-year-old man was admitted because of fatigue, dyspnea and subfebrilities. Heart rate was 116/min, sinus rythm blood pressure 110/60 mmHg. Chest film showed cardiomegaly with sings of interstitial pulmonary edema, echocardiography mild dilatation of the left ventricle with hyperkinetic wall motion and small pericardial effusion. Hemoglobin was 104 g/l, leukocyte count 13.5 x 10(9)/l with 30% of plasmatic cells. Serum protein electrophoresis demonstrated a monoclonal gammapathy, X ray studies of the skelet multiple osteolytic lesions. Diagnosis of plasmocytic leukemia-form of multiple myeloma was established and chemotherapy (vincristine + adriamycine + dexamethason) was started. Patient cardiac status deteriorated. Cardiac catheterisation demonstrated mean righ atrial pressure of 25 mmHg, mean pulmonary artery pressure of 28 mmHg and pulmonary artery wedge pressure of 24 mmHg. Co was 20.0 l/min (C.I. 11.5 l/min/m2). In continuing of chemotherapy and symptomatic therapy for heart failure patients status gradually improved and complete remission of the myeloma and normalisation of cardiac parameters was achieved. Heart failure in multiple myeloma patients has been attributed to amyloidosis of myocardium, hyperviscosity syndrome, co-existing CAD or anthracycline toxicity. HCOF should be considered in patients with clinical evidence of heart failure and normal left ventricular function.

In this review, we discuss the possible relationship between the clinical characteristics and the integration patterns of human T-cell lymphotropic virus type I (HTLV-I) proviral DNA in patients with adult T-cell leukemia/ lymphoma (ATL). Some ATL patients show unusual integration patterns such as multiple or defective HTLV-I and have clinical characteristics unlike those of most ATL patients who have the characteristic integration pattern of one complete provirus. Multiple HTLV-I integrations can be detected as two or more bands using the standard Southern blotting method when the tumor cellular DNA is digested with an endonuclease that does not cleave within the provirus. This includes cases of one tumor cell clone carrying two or more copies of the provirus, or alternatively two or more cell clones, each carrying one copy of the provirus. The former group of patients always manifest severe dyspnea and hypoxemia with unusual organ infiltrations including the retina and muscle and an extremely aggressive clinical course. On the other hand, the latter group of patients have an indolent course with skin lesions or small T lymphocytes with cleaved or lobulated nuclei. A solitary defective HTLV-I in some ATL patients can be detected as one smaller band after digestion of cellular DNA with an endonuclease that does not cleave within the provirus. These patients generally have a favourable clinical course with small cleaved or bilobulated T lymphocytes without lymphadenopathy or skin lesions. These findings suggest that there are clinical implications for the integration patterns of HTLV-I and this may be one of the explanations for the heterogeneous behaviour of the disease. Such studies may provide information on the relationship between virus integration and the clinical manifestations and also improve our understanding of the pathogenesis of ATL.

A 54-year-old male was admitted because of dyspnea on exercise. His peripheral blood revealed pancytopenia with severely hypoplastic bone marrow. Bone marrow aspiration showed a marked hypocellular marrow with 62.4% of blast cells. Cytochemical studies showed that peroxidase activity, alpha-nephtyl buthylate esterase activity and PAS reaction were negative, and that only ASD-chroloacetate esterase activity was positive. Surface marker analysis of blast cells showed positive result for CD5, 7, 33 and 34 antigens. The T-cell receptor beta gene was rearranged, but the immunoglobulin H chain gene showed a germ line configuration. Terminal Deoxynucleotydyl Transferase (TdT) was positive, but cellular surface and cytoplasmic immunoglobulin were not recognized. A diagnosis of hypoplastic mixed lineage leukemia was made and treated with low dose cytosine arabinoside, he resulted in complete remission. The relation between hypoplastic leukemia, AML-M0 and mixed lineage leukemia was also discussed.
