A 68-year-old woman was admitted in March 1997 because of lumbago, fever, vomiting, and general malaise. Laboratory data disclosed anemia and severe hypercalcemia (7.7 mEq/l). Multiple osteolytic lesions were detected in the patient's vertebra, pelvis, and bilateral tibia by x-ray films and 99mTc bone scintigrams. Bone marrow aspiration sample was not obtained due to dry tap. Marked myelofibrosis and proliferation of lymphoid cells were revealed by a bone marrow biopsy specimen. Immunohistochemical analysis showed that cells in the biopsy specimen were positive for L-26 and LCA, but not for UCHL-1. Gastrointestinal endoscopic examination found multiple polypoid lesions in the stomach; biopsy specimens of the lesion tissue disclosed invasion by B lymphoid cells. A diagnosis of diffuse large B cell lymphoma was thus made. THP-COP chemotherapy was performed, but only minimal response was obtained. Lymphoma cells subsequently invaded the brain stem, and the patient eventually died of respiratory failure.

Lymphomatoid granulomatosis is an angiodestructive, angioinvasive lymphoproliferative disorder. It involves most frequently lungs, central nervous system and skin. Recent studies indicate that lymphomatoid granulomatosis is an Epstein-Barr virus associated B cell disorder with a background of reactive T lymphocytes. In a 49 year old woman presenting with fever, malaise and pulmonary masses the diagnosis of lymphomatoid granulomatosis was established histologically by open lung biopsy. Following the initial diagnosis the patient was found to have gastric and skin involvement. The skin lesion was diagnosed as diffuse large B-cell lymphoma.

Immune abnormalities have been found in many patients receiving anti-epileptic drugs. However, the effects of carbamazepine are still conflicting. We report the case of a 31-year-old woman who began carbamazepine treatment because of idiopathic epilepsy of adulthood. After three years of treatment she developed arthralgias and malaise. Complete immunologic evaluation showed a total absence of immunoglobulin M with decreased levels of immunoglobulin A, positive antinuclear antibodies and monoclonal paraproteinemia type IgG-kappa. The possibility of B cell lymphoma or myeloma was ruled out. Skin testing was negative. Bone marrow examination was normal. After carbamazepine discontinuation, levels of IgA and IgM increased until reaching normal values over 3 years. The monoclonal gammopathy of undetermined significance also disappeared over this period. During this period of immunodeficiency, the patient did not complain of any infectious complications.

We conducted a phase II study to evaluate the efficacy and safety of cladribine (2-chlorodeoxyadenosine [2-CdA]) for patients with refractory or relapsed indolent B-cell lymphoma or mycosis fungoides. Forty-five patients were enrolled, and 43 patients, including 34 with follicular lymphoma, were eligible. 2-CdA was given by continuous intravenous infusion at a dose of 0.09 mg/kg daily for 7 consecutive days, and this schedule was repeated every 4 weeks up to a maximum of 6 cycles. The overall and complete response rates were 58.1% (25/43; 90% confidence interval, 44.5%-70.9%) and 14.0% (6/43), respectively. The disease progression-free proportions of all 43 eligible and all 25 responding patients at 2 years were 30.3% and 48.1%, respectively. Neutropenia and thrombocytopenia of grade 3 or 4 were observed in 53.3% and 37.8% of patients, respectively, with prolonged cytopenia observed in patients with increased numbers of treatment cycles. Nonhematologic toxicities of grade 3 or greater included diarrhea, arrhythmia, malaise, and gastrointestinal bleeding in 1 patient each, an increase in glutamic-pyruvic transaminase level in 2 patients, and infection in 5 patients. Two treatment-related deaths were observed. Four patients developed myelodysplastic syndrome (MDS) at 13 months to 2 years after completion of the 2-CdA treatments. 2-CdA is an active agent with acceptable toxicity for refractory or relapsed indolent lymphoma; however, prolonged myelosuppression and the potential development of MDS should be carefully monitored.

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.

A 54-year-old woman was admitted due to high-grade fever, cervical lymphadenopathy and general malaise in May 2003. On examination, severe anemia was noted, direct Coombs and cold hemagglutinin tests were positive and the haptoglobin level was low in the peripheral blood. However, a bone marrow examination revealed marked erythroid hypoplasia. A diagnosis was made of co-existing combined type autoimmune hemolytic anemia (AIHA) and erythroid hypoplasia. A pathologic diagnosis of de novo CD5-positive diffuse large B-cell lymphoma (de novo CD5+ DLBCL) was made based on a cervical lymph node biopsy. The patient was treated with CHOP accompanied by rituximab (R-CHOP), resulting in complete remission after 3 courses of chemotherapy. The AIHA and erythroid hypoplasia subsided after 2 courses of R-CHOP. The sera obtained during erythroid hypoplasia significantly inhibited the growth of erythroid progenitor cells (erythroid colony-forming units, CFU-E) from her bone marrow collected after recovery. We report here a patient with de novo CD5+ DLBCL associated with both AIHA and erythroid hypoplasia, suggesting that the lymphoma triggered an abnormal immunity which generated some humoral inhibitors against erythropoiesis.

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.

A 59-year-old woman received eight cycles of R-CHOP for diffuse large B-cell lymphoma from July, 2004. Pretreatment HBV serological tests were positive, however, the transaminases were within normal limits, and she remained asymptomatic. Lamivudine (LAM) was administered orally from the start of R-CHOP. HBV-DNA levels gradually decreased and were not detected until December, 2004. LAM was administered until 3 months after the end of chemotherapy, with the entire treatment lasting less than 1 year. Two months after the cessation of treatment, she was re-admitted for general malaise. A liver function test revealed severe abnormalities, and HBVDNA levels were increased. Clinically, she was experiencing acute hepatitis due to HBV reactivation. She was then treated with LAM and interferon-beta immediately. Her HBV-DNA levels soon decreased, and liver function improved.

Intravascular large B-cell lymphoma (IVL) is a rare subtype of B-cell lymphoma presenting with neurological and dermatological lesions in addition to generalized symptoms such as fever and malaise. It may also be associated with variable manifestations of affected organs due to extranodal progression predominantly in the lumen of the small vessels. Here, we report a case of IVL with the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) as the sole manifestation at the initial presentation. The present case suggests that hormonal disturbances may progress in advance in IVL, before generalized symptoms develop.

Early diagnosis of intravascular large B-cell lymphoma (IVLBCL) is difficult, but is critical for longer survival for the patients. We report a case of IVLBCL that was diagnosed with the help of FDG-PET. A 76-year-old woman was referred to us for the evaluation of her elevated serum LDH. She presented with general malaise and high fever. There were no skin lesions or neurological involvement. FDG-PET imaging showed increased uptake of FDG in the vertebra, bilateral femurs, sternum, and iliac bones. A diagnosis of IVLBCL was made by bone marrow biopsy. She was successfully treated with rituximab and modified CHOP therapy.
