The study aimed at the diagnosis of toxoplasmosis in 73 children with malignancy; 31 with lymphoma (22 with Hodgkin's and 9 with non-Hodgkin's lymphoma) and 42 with leukemia (34 with acute lymphoblastic leukemia and 8 with acute myelogenic leukemia). In positive cases toxoplasmosis was manifested by any of the following; fever, lymph node enlargement, neurological manifestations and/or hepatosplenomegaly. The indirect hemagglutination test (IHA) for toxoplasmosis detected 4 (5.4%) positive cases with malignancy, 2 with Hodgkin's lymphoma, one with non-Hodgkin's lymphoma and one with acute lymphoblastic leukemia. The immunoglobulin M enzyme-linked immunosorbent assay (IgM ELISA) detected only one (1.4%) case with Hodgkin's lymphoma. Immunoglobulin G (IgG) ELISA detected 6 (8.2%) positive cases, 3 with Hodgkin's lymphoma, one with non-Hodgkin's lymphoma and 2 cases with acute lymphoblastic leukemia. Polymerase chain reaction for detection of parasite DNA in blood (PCR) was the most useful in diagnosing toxoplasmosis with malignancy, as it was able to detect 9 (12.3%) positive cases; 5 (6.8%) with Hodgkin's lymphoma, one (1.4%) with non-Hodgkin's lymphoma and 3 (4.1%) with acute lymphoblastic leukemia. No positive toxoplasmosis cases were detected with acute myelogenic leukemia by any of the above methods.

A 38-year-old male presented with fever and hepatosplenomegaly. Cells that had infiltrated to the bone marrow were consistent immunophenotypically and genotypically with natural killer (NK) cells. Oligoclonal Epstein-Barr virus infection was detected in the bone marrow cells. The patient was diagnosed as a case of aggressive NK cell leukemia/lymphoma. Combined chemotherapy was not effective and death occurred shortly after presentation. Although the karyotype of this case was too complicated to be accurately identified only by G-banding, spectral karyotyping (SKY) analysis not only identified all chromosomal materials of unknown origin, but also detected the cryptic translocation on the apparently normal chromosome. Moreover, SKY analysis identified der(4)t(4;14)(q12;q11.2). The chromosomal band 14q11.2 is a recurring breakpoint in T-cell non-Hodgkin's lymphoma, and is also the locus of the delta chain of the T-cell receptor. To our knowledge, t(4;14)(q12;q11.2) in T-cell or NK-cell malignancies has not been previously reported.

The presence of serum cold agglutinin can be the initial presentation of lymphoproliferative diseases. Conditions with persistent cold agglutinins are a spectrum of diseases that vary from benign lymphoproliferation of the "autoimmune-like chronic cold agglutinin disease" to malignant lymphoma. We report a case of a 72-year-old woman who presented with severe anaemia, hepatosplenomegaly and episodes of peripheral haemagglutination precipitated by cold exposure. The haemoglobin was 5.6 g/dL with a cold agglutinin titer of 1:256 at 4 degrees C and 1:8 at room temperature (30 degrees C). The cold agglutinin showed anti-I specificity and kappa light chain restriction. Peripheral blood showed atypical lymphoid cells with a B-cell immunophenotype. Immunoglobulin gene rearrangement study by polymerase chain reaction (PCR) showed an amplified band at 100 bp, consistent with a clonal proliferation of B-lymphocytes. We believe that our patient had cold antibody haemolytic anaemia as the initial presentation of a low-grade non-Hodgkin's lymphoma. The association of cold antibody haemolytic anaemia with low-grade B-cell lymphoma is unusual.

A case of angiotropic B-cell lymphoma associated with hemophagocytic syndrome (HPS) has been reported. In addition to fever, pancytopenia, hepatosplenomegaly, and lack of lymphadenopathy, unique clinical features, such as syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and pulmonary infarction, were manifested. Both soluble interleukin-2 receptor (sIL-2R) and IL-6 were elevated in the patient's sera in addition to an increase of serum lactate dehydrogenase and ferritin. In contrast, tumor necrosis factor-alpha and interferon-gamma were within normal ranges. Serum antibodies against Epstein-Barr virus and cytomegalovirus showed a past infection pattern. An autopsy examination revealed systemic intravascular proliferation of lymphoma cells with a B-cell phenotype, confirming the diagnosis of angiotropic B-cell lymphoma. Moreover, SIADH was suggested to result from the infiltration of tumor cells into the pituitary gland. Triple association of angiotropic B-cell lymphoma, HPS and SIADH is quite rare. Therefore, the present case seems to be helpful for clarifying the mechanism for HPS of non-Hodgkin's lymphoma with B-cell origin.

A 25-year-old man was admitted to our hospital because of hematuria, anemia and thrombocytopenia. Laboratory examinations revealed an increased number of bone marrow megakaryocytes and an increased level of platelet-associated immunoglobulin G, suggesting immune thrombocytopenia. Computed tomography of the abdomen showed enlargement of the bilateral kidneys with multiple low-density areas, although neither lymphadenopathy nor hepatosplenomegaly was evident. After amelioration of the thrombocytopenia by prednisolone therapy, open renal biopsy was performed and a diagnosis of diffuse large B-cell non-Hodgkin's lymphoma was made. The patient achieved complete remission after CHOP therapy. This was thought to be a rare case of primary renal non-Hodgkin's lymphoma initially presenting as immune thrombocytopenia, which was treated successfully by chemotherapy.

Two children with non-Hodgkin's lymphoma (NHL) as the presenting illness of acquired immunodeficiency syndrome (AIDS) are described. There was a delay in diagnosing the underlying AIDS in both cases. In the first case, an 18-month-old boy with stage IV, high-grade,T-cell NHL, the diagnosis of underlying AIDS was suspected only when he developed recurrent and profound opportunistic infection during chemotherapy. The second case, an eight-month-old female infant presented initially with hepatosplenomegaly and thrombocytopenia of undetermined cause. She had progressive abdominal distension and swelling of her right eye one year later due to high grade B-cell NHL. She was later found to be sero-positive for HIV during pre-chemotherapy screening. As the prevalence of HIV infection continues to increase, HIV infection should be considered in the differential diagnoses of childhood hepatosplenomegaly and thrombocytopenia, and as a possible underlying cause of childhood cancer, especially NHL.

Malignant lymphomas have been reported previously to coincide with adenocarcinomas of the stomach and, rarely, the kidney, breast, colon, liver, or lung. Here, we describe the first case to our knowledge of a malignant lymphoma and an extensive disease small cell cancer of the lung. A 60-year-old male was admitted for severe back pain and was found to have multiple enlarged lymph nodes, hepatosplenomegaly, and bilateral pleural effusions. A B-cell non-Hodgkin's lymphoma (NHL) was diagnosed from biopsies of the stomach and liver. Further staging revealed a dense infiltration of the bone marrow by both a small cell lung cancer and a malignant lymphoma. Both tumors responded well to chemotherapy. This unique case report demonstrates that the simultaneous occurrence of small cell lung cancers and malignant lymphomas is extremely rare and may effectively be treated with chemotherapy.

A rare simultaneous occurrence of multicentric Castleman's disease, non-Hodgkin's lymphoma, and Kaposi's sarcoma was diagnosed in a 70-year-old man who presented with fever, polyarthralgia, weight loss, vascular purpura, anemia, generalized lymphadenopathy, and hepatosplenomegaly. He had no risk of HIV infection and serological tests for HIV were negative twice, but a low number of T-cells and a reversed CD4/CD8 ratio were observed. During hospitalization, he developed Kaposi's sarcoma at the right sole. Lymph node biopsies revealed multicentric Castleman's disease together with a large B-cell lymphoma, which showed monotypic IgM-lambda lymphocytes. To our knowledge, this is the first report in which systemic manifestations of all three diseases occurred simultaneously prior to any specific treatment. The altered immune status and human herpesvirus-8 infection might have played a role in the pathogenesis of this occurrence.

Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) is a primary lymphoproliferative T-cell disorder, currently classified as a peripheral T-cell non-Hodgkin's lymphoma. AILD is characterized by generalized lymphadenopathy, hepatosplenomegaly, immunological abnormalities, polyclonal hypergammaglobulinemia and anemia. We report a case of AILD in an 80-year-old male who presented with a generalized pruritic maculopapular eruption and fever following doxycycline administration. The maculopapular rash progressed to formation of confluent nodules, plaques and finally erythroderma with lymphadenopathy and hepatosplenomegaly. Blood analysis revealed an elevated erythrocyte sedimentation rate and polyclonal hypergammaglobulinemia. Lymph node biopsy showed almost complete effacement of the nodal architecture with diffuse proliferation of small vessels forming an arborizing network, surrounded by atypical lymphocytes, usually CD3+ CD4+ and occasionally CD3+ CD8+. There were also larger cells (immunoblastic shape) that displayed CD20 positively, some scattered plasma cells, and eosinophils. Histology of a cutaneous lesion showed spongiosis and infiltration of the epidermis by atypical lymphocytes with large hyperchromatic nuclei, perivascular dermal lymphocytic infiltrate (CD3+) mixed with plasma cells and occasional large immunoblasts (CD20+). During hospitalization the patient developed hemolytic anemia (Coombs positive) and lung metastases. The prognosis of AILD is generally poor, with a median survival of less than 20 months. Our patient died two and a half months after the diagnosis was made due to sepsis caused by Staphylococcus aureus isolated in hemoculture.

A 31-yr-old man presented with a 1-wk history of fever, chills, weakness, headaches, and a significant 20-lb weight loss over the preceding 2 months. His past medical history was relevant for liver amebiasis during childhood. Two days before admission, the patient noticed jaundice. He denied abdominal pain or other GI symptoms, and there was no history of alcohol intake, medications, or illicit drugs. His physical examination revealed generalized jaundice, hepatosplenomegaly, and bilateral leg edema. Neurologically, the patient was agitated, with periods of disorientation, and he had bilateral flapping. His blood tests revealed pancytopenia, renal failure, liver failure, and coagulopathy. Because the patient had a fever, hepatosplenomegaly, and pancytopenia, a further workup also included a bone marrow and liver biopsy. No conclusive diagnosis could be made from the above tests, and the patient died 5 days after admission. Postmortem evaluation, including flow cytometry and gene rearrangement in the tissue obtained from the liver, revealed large B cell lymphoma. This case illustrates an unusual presentation of hepatic non-Hodgkin's lymphoma. Current information regarding this entity is scant, mainly owing to its rarity. We present a review of the literature, including the incidence, presentation, treatment, and prognosis of primary hepatic lymphoma.
