An 84-year-old female was admitted to our hospital because of fever. Physical examination and computed tomography revealed hepatosplenomegaly without lymphadenopathy. Anemia and thrombocytopenia were noted and the serum levels of LDH, IL-6 and sIL-2R were elevated. Bone marrow aspiration showed infiltration of lymphoma cells and proliferation of histiocytes with hemophagocytosis. Southern blot analyses revealed rearrangements of both IgJH and IgJK genes. She received corticosteroids with improvement of her general state but she died on the 110th hospital day. Necropsy of the spleen showed diffusely proliferating large lymphoma cells, immunoreactive for B cell marker L-26, and scattered histiocytes with hemophagocytosis.

While various infectious agents have been reported to induce hemophagocytic syndrome (HPS), protozoan malaria-associated HPS has not been documented. We describe a patient with Plasmodium falciparum malaria complicated by HPS. A 24-year old man with a history of recent travel in tropical areas was hospitalized with high fever and hepatosplenomegaly. Blood smear showed many of the erythrocytes infected with the ring form of P. falciparum. Laboratory data disclosed bicytopenia with coagulopathy, a high serum level of LDH, hyperferritinemia and hypercytokinemia. Bone marrow smear demonstrated proliferation of mature histiocytes with vivid hemophagocytosis. He was free from other active, disseminated viral, bacterial and fungal infections which have been reported to induce HPS. He recovered rapidly from HPS after resolution of the original malarial infection.

Involvement of malignant lymphoma in the liver inducing fulminant hepatic failure has rarely been reported. Therefore, a close association between some lymphoma types with severe liver damage and the mechanism underlying the liver damage is intriguing. Three malignant lymphoma cases, which were clinically diagnosed as fulminant hepatitis, were collected from the autopsy records of Kawasaki Medical School (Kurashiki, Japan). All three cases were characterized by the presence of hepatosplenomegaly without superficial lymph node swelling, high elevation of transaminase and lactate dehydrogenase (LDH; especially LDH-2), and a quite aggressive clinical course. Immunohistochemically, the tumor cells in all three cases were positive for T cell intracellular antigen (TIA-1), which is a cytolytic protein in cytotoxic T and natural killer (NK) cells. The lymphomas were CD8+ peripheral T cell lymphoma (case 1), CD56+ T/NK cell lymphoma (case 2), and T cell lymphoma in a patient with mosquito hypersensitivity (case 3). Epstein-Barr virus infection was demonstrated on the tumor cells of cases 2 and 3 using an in situ hybridization method and those cases showed high titers of serum interferon-gamma and Fas. Frequent apoptosis of liver cells, where the lymphoma cells had infiltrated, was revealed by a terminal deoxyribosyl transferase-mediated deoxyuridine nick end-labeling (TUNEL) method. The findings in this study suggest that fulminant hepatic injury is closely associated with cytotoxic molecule TIA-1 expression of the lymphoma cells and that some specific mechanism may be involved in liver damage.

A 26-year-old female was admitted because of multiple fractures in lower extremities. While in the hospital, she developed a high fever and generalized skin eruption. Physical examination revealed bilateral cervical lymphadenopathy and mild hepatosplenomegaly. The white cell count was 11,200 with 11% atypical lymphocytes. Serum GOT, GPT, LDH were markedly elevated. Infectious mononucleosis was suspected, but the serological test for EB virus did not show evidence of acute EB virus infection. Anti-HSV, CMV, hepatitis A virus antibody titers also did not show significant change during the coarse. The serological test for HHV-6 only showed increased titer of IgM and IgG antibodies. Rapidly elevated IgG antibody titer was indicative of reactivation of HHV-6. So, she was diagnosed as mononucleosis-like syndrome caused by HHV-6, probably reactivated infection. Her symptoms gradually disappeared during a month.

The Asian variant of intravascular large B-cell lymphoma (IVL) is characterized by hemophagocytic syndrome, i.e. the clinical features include pancytopenia, hepatosplenomegaly, and rarely mass formation. It usually lacks any neurological abnormality or skin lesions, which are typical features of classical IVL. Sixty-seven cases of IVL reported in Japan since 1990 were classified into two groups, and their clinicopathologic features were compared. Forty-five cases of IVL that met the clinical and laboratory criteria for the Asian variant were classified into Group A (average: 66 yr; male: 62%), and 22 cases that did not meet the criteria were classified into Group C (average: 65 yr; male: 73%). Hemophagocytosis was described only in Group A. The positivity rates for bone marrow invasion, fever, hyperbilirubinemia and elevated levels of LDH and CRP were significantly (p = 0.0037, p < 0.0001, p = 0.0428, p = 0.0108 and p = 0.0008, respectively) higher in Group A than in Group C. On the other hand, the positivity rates for neurological abnormality and skin lesions were significantly (p < 0.0001 and p = 0.0011, respectively) higher in Group C than in Group A. Our reassessment of the reported cases of IVL in Japan identified two major categories of IVL: the classical form and the Asian variant.

A 9-year-old-boy with severe haemophilia A (factor VIII < 1%) developed colicky abdominal pain with swelling in the left iliac fossa for 4 weeks. His LDH level was 1423 IU/l (normal range < 220 IU/l) and his uric acid, 6.8 mg/dl. A computerised tomography (CT) scan of the abdomen demonstrated a tumour of the terminal ileum and mild hepatosplenomegaly. Pre-operative screening for factor VIII inhibitor was negative. Post-operatively, the patient needed high doses of factor VIII to maintain haemostasis. The tumour was found to be a high-grade lymphoma of Burkitt's type. He recovered from his operation and chemotherapy was commenced. Investigations demonstrated an anti-von Willebrand factor (VWF) antibody. He subsequently relapsed and died of progressive disease. Development of anti-VWF antibody in lymphoma is well known, but development of this antibody in a haemophilia A patient developing lymphoma has not been reported. The present case shows that antibody to VWF should be considered as a possible reason for an increased factor VIII requirement in such patients.

A 7-year-old previously healthy Czech boy was admitted due to fever, hepatosplenomegaly and pancytopenia. Aspiration of bone marrow revealed no signs of hemoblastosis (nor hemophagocytosis). He was treated with antibiotics and virostatics without effect. Progression of hepatosplenomegaly and pancytopenia induced suspicion of hemophagocytic lymphohistiocytosis (HLH). Five weeks later, bone marrow hemophagocytosis of erythrocytes, nuclear elements and platelets was detected. He was given corticoids and intravenous immunoglobulins and transferred to our haematology department. Laboratory findings of mild pancytopenia, hypofibrinogenaemia, hyperlipidaemia and elevated levels of ferritin, LDH and immunoglobulins were compatible to the diagnosis of HLH. Immunologic evaluation revealed T-lymphocyte activation. Appropriate immunosuppressive treatment with Dexamethasone, etoposide and Cyclosporine A was launched, followed by transient subside of fever and improvement of peripheral blood count, but not regression of hepatosplenomegaly. Four weeks later, relapse of fever and deterioration of blood count led to intensification of immunosuppression. However, no effect was evident. Moreover, hypertrophic cardiomyopathy with ventricular arrhythmia occurred. Treatment with antilymphocytic globulin for resistant course of HLH was planned. Before that, a fifth bone marrow aspiration was performed. Surprisingly, many Leishmania amastigotes were observed within marrow macrophages. Leishmania infection was confirmed by positive serology. Immunosuppressive treatment was withdrawn and changed for causal treatment with liposomal Amphotericin B. Positive clinical effect with subside of fever was evident in ten days, splenomegaly gradually resolved during three weeks, restoration of normal blood count lasted six weeks. No relapses of HLH nor leishmaniasis occurred. In control bone marrow aspirate performed three months later, the parasites were not detected. Ten months after the event, the patient is in complete remission of HLH with normal immunologic parameters. Most probably, he contracted visceral leishmaniasis during a visit of a Neapol area in Italy 3 months before the onset of the disease.

A 36-year-old woman was referred to our hospital because of leukocytosis in June 2000, and was admitted to our hospital and diagnosed as having adult T-cell leukemia/lymphoma (ATL; acute type). Complete remission was achieved with eight courses of CHOP therapy, but ATL relapsed and she was readmitted to our hospital in September 2001. Laboratory examination showed elevated levels of serum LDH and soluble IL-2 receptor, and hypercalcemia. CT examinations showed swelling of the abdominal lymph nodes and hepatosplenomegaly. CHOP therapy improved the symptoms, but recrudescence soon occurred. After two courses of salvage therapy which resulted in no remission, the patient received an allogeneic peripheral blood stem cell transplant (allo-PBSCT) from her HLA-matched sibling donor after preconditioning with BU + CY in January 31, 2002. Cyclosporin A (CsA) and short-term MTX were used to prevent GVHD. Bone marrow engraftment was prompt and acute GVHD was not found. Two months later, recurrence was seen in the form of subcutaneous tumors, but the tumors spontaneously disappeared following CsA withdrawal. At the time of writing, eight months after the transplant, remission has been maintained. A graft-versus-leukemia (GVL) effect may have been the curative action in this case.

A 66-year-old man was admitted to our hospital for fever on January 19, 1998. He began showing periodic high fever in June 1997 and an increased serum LDH in August 1997. His history included surgery for esophageal cancer in 1993. On admission, the patient's body temperature was 38.5 degrees C. Physical examination was negative for lymphadenopathy, hepatosplenomegaly, and skin rash. Peripheral blood revealed a hemoglobin level of 8.6 g/dl and a platelet count of 7.9 x 10(4)/microliter. Bone marrow examination showed hypocellularity with marked histiocytic hemophagocytosis. The various bacterial cultures were negative. Serum LDH was elevated to 1,606 IU/l, and ferritin was greater than 3,000 ng/ml. Antinuclear antibodies were negative. No significant elevation of viral antibody titers including that to Epstein-Barr virus was found. Hemophagocytic syndrome (HPS) was diagnosed, but no underlying diseases was identified. The patient's condition was complicated by interstitial pneumonia and pleural effusion. gamma-globulin and pulse methylprednisolone both proved ineffective for the HPS; however, complete remission was achieved with cyclic intravenous administration of etoposide (VP-16, 150 mg/day). Interestingly, the interstitial pneumonia resolved promptly with etoposide therapy. The patient relapsed, in July 2001, exhibiting high fever, cytopenia, and marrow hemophagocytosis. His condition was ameliorated by administration of etoposide. This was a rare case of chronic and recurrent HPS of unknown etiology accompanied by interstitial pneumonia. Etoposide should be considered as a primary therapy for HPS and its complications in cases such as our patients.

Neurological and skin involvements usually dominate the clinical presentation of intravascular lymphomatosis (IL), while fever is the most frequent general sign. However, an onset only characterized by fever of unknown origin (FUO) has been rarely reported. We would like to describe a further case of IL, which presented a long-lasting FUO before the diagnosis. At admission, physical examination detected hepatosplenomegaly without lymph nodes enlargement or dermatological or neurological abnormalities. Significant laboratory data included severe anemia, leukopenia, thrombocytopenia, and increased serum LDH. Moreover, a chest CT evidenced bilateral multiple pulmonary infiltrates and pleural effusion. After the development of proteinuria, a diagnosis of large B-cell intravascular lymphoma was made with a renal biopsy 10 months after the onset of the clinical manifestations. So far, more than 100 cases of IL have been reported and the diagnosis often turned out to be difficult, as clinical signs did not point to a lymphoproliferative disorder. This report confirms that FUO is not only frequently associated with IL but that it even marks the real onset of the disease. We are then tempted to conclude that undiagnosed fever is not so rare in IL and if we call it FUO, it is only because diagnosis is necessarily elusive and hence time-consuming.
