A 76-year-old woman was admitted to the University of Tokyo Hospital in June 2002 because of fever of unexplained origin. She had suffered a high grade fever (above 39 degrees C) for 2 weeks. Initial evaluation revealed elevated CRP and pancytopenia. Bone marrow aspiration (BMA) was performed, and a diagnosis of pure red cell aplasia (PRCA) was made. One month later, she complained right hypochondrial pain, and aspiration from her enlarged gall bladder was performed. Her fever and PRCA ameliorated, and she was discharged in August, 2002. In April 2003, she was readmitted to our hospital because of the recurrence of high grade fever, elevation of CRP, and pancytopenia. BMA was performed and revealed diffuse large B cell lymphoma. In the case of extranodal lymphoma which only presents pyrexia, differentiation with other diseases is very difficult especially in the elderly. It is necessary to bear in mind the possibility that a hematological malignancy, especially malignant lymphoma, can be latent in elderly patient with fever of unknown origin.

A 40-year-old, gravida 3, para 2 woman was initially referred to our department at 31 weeks' gestation complaining of fever, night sweats, malaise in association with jaundice and pancytopenia. Cesarean section with excisional iliac lymph node biopsy was carried out following a period of expectant management. An 1,840 g healthy male infant with an Apgar score of 9 at 34 weeks of gestation was delivered. Histologic examination of the excised lymph node revealed non-Hodgkin's lymphoma (Histiocyte and T cell predominant B cell lymphoma). The patient was evaluated to have Stage II B disease. A chemotherapy regimen of CHOP/Rituximab was instituted with successful maternal-fetal prognosis.

During treatment for inflammatory bowel disease (IBD) 2 men with ulcerative colitis, aged 52 and 38 years, and a 37-year-old man with Crohn's disease developed Epstein-Barr virus (EBV)-related non-Hodgkin's B-cell lymphoma. The first 2 patients underwent proctocolectomy and the use of immunosuppressive agents was discontinued, after which the lymphoma disappeared. The third patient had icterus, hepatosplenomegaly and pancytopenia; he died from multiple organ failure. Azathioprine and 6-mercaptopurine are first choice therapy in the treatment of steroid-refractory IBD. These immunomodulating agents are associated with the development of EBV-positive lymphomas in the setting of solid organ transplantation. This type of lymphoma is a rare complication in IBD, although the incidence in referral centres appears to be increasing. Since azathioprine is an important drug in IBD, there is a need for identification of IBD patients at risk of developing a lymphoma. EBV-DNA in plasma or in faeces may be a candidate tumour marker.

X-linked lymphoproliferative disease is a rare T and NK cell immune deficiency which most frequently presents as fulminant infectious mononucleosis following infection with the Epstein-Barr virus (EBV). We report the case of a 4-year-old boy from a Spanish family presenting with severe infectious mononucleosis. In the course of the disease he developed hepatic failure, pancytopenia and neurologic impairment, leading to death after less than 2 months. The results of bone marrow biopsy and autopsy indicated a histological diagnosis of both high-grade B-cell lymphoma and virus-associated haemophagocytic syndrome, thereby confirming the simultaneous presence of two different manifestations of X-linked lymphoproliferative disease (XLP) in this patient. The family history revealed four close male relatives dying under similar circumstances, one of whom died following a vaccination against measles. Molecular genetic studies identified a novel mutation in the SH2D1A gene in several members of the family, establishing the diagnosis of XLP. Fatal EBV infection in male infants is highly indicative of XLP. Virus-associated haemophagocytic syndrome and B-cell lymphoma can occur concomitantly and may be difficult to distinguish due to their similar histological pictures.

Plasmablastic lymphoma is an aggressive subtype of diffuse large B-cell lymphoma that is mainly observed in patients with the human immunodeficiency virus (HIV) infection, and it tends to arise in the oral cavity. We present a case of an HIV-infected patient with plasmablastic lymphoma with prolonged survival. The 30-yr-old woman was found to have an oral lesion at the time of the diagnosis of HIV infection. Histological and immunochemical examination of biopsy of the oral lesion showed plasmablastic lymphoma (CD138+). She received two cycles of cyclophosphamide, vincristine, doxorubicin, and prednisolone (CHOP) that started 10 weeks after the initiation of antiretroviral therapy. The continuing pancytopenia and an adenoviral febrile infection did not permit further antineoplastic treatment. A gradual decrease of the oral lesion was noted after the second cycle of chemotherapy that led to the disappearance of the lesion 7 months later. The patient remains in complete remission 61 months after the diagnosis of plasmablastic lymphoma.

A 63-year-old male presented with fever and general malaise in June 2004. On admission hepatosplenomegaly was apparent, but without lymphadenopathy. The laboratory examination revealed pancytopenia and increased levels of lactate dehydrogenase, direct bilirubin and soluble interleukin-2 receptor. Histological analysis of the bone marrow biopsy specimen demonstrated proliferation of atypical lymphoid cells positive for CD20 in the small capillaries, leading to the diagnosis of the Asian variant of intravascular large B-cell lymphoma (AIVL). The presence of rearrangement of the immunoglobulin gene confirmed the diagnosis. The patient responded well to CHOP therapy followed by seven courses of rituximab-combined CHOP therapy and has remained in complete remission up to the present. This case implies that bone marrow biopsy could be a useful examination for diagnosing AIVL and that rituximab-combinedchemotherapy could improve survival in patients with the disease.

We report a case of Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorder (PTLD) after CD34-selected autologous peripheral blood stem cell transplantation (PBSCT). A 54-year-old woman with multiple myeloma underwent CD34-selected autologous PBSCT. The patient's post-transplantation course was complicated by fever, pancytopenia and CMV antigenemia. On day 128 post PBSCT, a skin biopsy from an erythematous nodule on the right anterior chest revealed a deep dermal infiltrate of atypical CD20 and CD79a-positive B-cells with centroblastic large cell morphology. EBV reactivation was confirmed by immnohistochemistry, in situ hybridization and Southern blot analysis. These findings represent monomorphic PTLD having pathological features of a large cell-type B-cell lymphoma. Bone marrow aspiration also demonstrated hemophagocytic syndrome (HPS), accompanied with infiltration of EBV-positive B-cells. Despite treatment with rituximab and hydroxyurea, the patient died 155 days after transplantation.

In immunosuppressed patients, a high rate of complications due to opportunistic infection is known. We report the case of a 36 year old patient with ulcerative colitis and a septic complication with ongoing pancytopenia. Due to colonic perforation, colectomy had to be performed. Despite this intervention, the septic constellation persisted. The pancytopenia in peripheral blood counts also persisted with the necessity of repetitive transfusions. A bone marrow biopsy showed an infiltration with Leishmania bodies in macrophages. Tissue culture allowed for typing of the parasites as belonging to the L. donovani/infantum complex, DNA sequencing confirmed infection with L. infantum. This infection must have been contracted during a vacation on Mallorca about 1.5 years earlier. Administration of liposomal amphotericin B cured the patient. Surprisingly, histological examination of the resected colon reveiled the presence of an immunoblastic B-cell lymphoma. In this case, immunosuppression was a prerequisite for the manifestation of leishmaniosis.

We report a case of B-cell lymphoma during pregnancy associated with hemophagocytic syndrome and placental involvement. A 33-year-old Japanese woman developed pancytopenia, hepatosplenomegaly, and a high-grade fever for 2 weeks at 23 weeks of gestation. The demonstration of hemophagocytes in her bone marrow confirmed the diagnosis of hemophagocytic syndrome. She was referred at 25 weeks of gestation for evaluation of hemophagocytic syndrome. The screening for infection and autoimmune disease was negative. Clinical manifestation suggested malignant lymphoma as the underlying cause of hemophagocytic syndrome, but we could not confirm any lymphoma involvement in the bone marrow aspiration. Glucocorticoid therapy did not arrest the hemophagocytic process. Her general status worsened, and reduction of amniotic fluid was noted. At 28 weeks of gestation, we performed a Cesarean section because of fetal distress. Microscopic examination of placental specimen revealed diffuse infiltration of large, atypical lymphoid cells involving the intervillous space. Using immunohistochemical study, we made the diagnosis of B-cell lymphoma. R-CHOP (rituximab/cyclophosphamide/doxorubicin/vincristine/prednisone) chemotherapy was administered on the eighth postpartum day. After 2 cycles of R-CHOP chemotherapy, hematopoiesis became normal and hepatosplenomegaly almost completely disappeared. After 6 cycles of R-CHOP, the patient received autologous peripheral-blood stem cell transplantation, and she is currently in complete remission 1 year after diagnosis. The infant did well, without clinical or laboratory manifestations of malignant lymphoma. In cases with suspected malignancy associated with hemophagocytic syndrome during pregnancy, it is important to verify placental microscopic examination for evaluating the causative disease of hemophagocytic syndrome.

A 70-year-old woman complained of mild shortness of breath. Laboratory findings revealed pancytopenia, positive lupus anticoagulant and severe hypocomplementemia without anti-nuclear or anti-DNA antibodies. After the failure of prednisolone treatment, an acquired C1-esterase inhibitor (C1-INH) deficiency was diagnosed. There were no episodes of angioedema or deep vein thrombosis. Three months later, extreme splenomegaly was detected. Lymph node biopsy suggested splenic marginal zone B-cell lymphoma. Acquired C1-INH deficiency due to a lymphoproliferative disorder should be considered as a possible diagnosis for patients with severe hypocomplementemia.
