A case of B cell lymphoma with clinical and histological features of malignant histiocytosis was described. A 57-year-old male was admitted to Shinshu University Hospital because of transverse myelopathy. Five months before admission, he noticed urinary disturbance, which progressed to urinary obstruction. The following month, bilateral muscular weakness appeared in his legs. A few days later he could not stand up, and was admitted to a local hospital. Neurological examination revealed sensory disturbances below the level of Th12 in all modalities, and marked weakness and hyperreflexia in the lower limbs. A spinal tumor was suspected. However, myelography showed no abnormality. The patient's condition worsened and he became bed-ridden in February 1990. He was transferred to Shinshu University Hospital for further evaluation. On admission he was poorly nourished with fever, anemia, hepatomegaly, and bilateral pretibial pitting edema. No lymphadenopathy was observed. Neurological examination showed total sensory loss below the level of Th12, spastic paraplegia, hyperreflexia in the legs, and urinary obstruction. Laboratory findings revealed an elevated erythrocyte sedimentation rate, increased CRP, pancytopenia, and hypoalbuminemia. Serum level of IgG, IgA, IgM, LDH, ALP, GPT and total bilirubin were increased. CSF and MRI imaging of the spinal cord were normal. Proliferation of atypical histiocytes with marked erythrophagocytosis, which is a characteristic pathological feature of malignant histiocytosis, was observed in peripheral blood and aspirated bone marrow. Immunoenzyme staining of bone marrow using monoclonal antibody L-26, which is a B-cell marker, revealed B-cell lymphoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Two cases of Richter's syndrome are reported (in a 62 and 64 years old man) consistent with the appearance of B cell lymphoma of high malignancy in the course of CLL (low malignancy B cell lymphoma). In one patient, after 8-, and in the other one--after 53 months since the diagnosis of CLL, there was rapid clinical deterioration with lymphadenopathy, hepato- splenomegaly, fever and progressive cachexia, anemia and thrombocytopenia and leukopenia, unrelated to treatment. Both patients died, 4 and 3 months respectively, since the appearance of these symptoms. In the first cases Richter's syndrome was diagnosed histopathologically from the autopsy material. In the liver, spleen, adrenals and bone marrow, in addition to the characteristic infiltrates of CLL (small lymphocytes) there were areas of large cell proliferation consistent with high malignancy lymphoma. In the other case, the infiltrates of large cell lymphoma were found in the gall bladder removed because of acute cholecystitis, and in the lymph node from the hepatic hilar area. Immunocytochemical studies performed on the biopsy material indicated that the neoplastic cells had markers of B lymphocytes and cytoplasmic IgM kappa, as lymphocytes of CLL. In patients with CLL, who display rapid clinical deterioration and general symptoms with cachexia, the possibility of Richter's syndrome should be considered, and appropriate morphological studies performed.

This report describes a case of B cell lymphoma, the clinicopathological features of which are quite similar to those of malignant histiocytosis. The clinical features included fever, anemia, and marked hepatosplenomegaly without lymphadenopathy. Histological findings revealed diffuse and noncohesive proliferation of cytologically atypical cells and benign-appearing histiocytes in the splenic red pulp, where the erythrophagocytosis was frequently found. Immunological studies, however, revealed a B cell nature of proliferating atypical cells. Accordingly, the histology of this patient was interpreted as a neoplastic proliferation of B cells accompanied by marked proliferation and activation of the histiocytes.

A 47-year-old man, was referred for evaluation of asymptomatic splenomegaly in September 1981, and a diagnosis of hairy cell leukemia (HCL) at the initial clinical stage was made. The patient remained asymptomatic until May 1985, when splenectomy was performed because of anemia and splenomegaly. Bone marrow and liver biopsy specimens showed diffuse infiltration by abnormal tartase resistant acid phosphatase (TRAP) positive lymphocytes with typical aspect of hairy cells. Four months later, he developed fever of unknown origin and, at laparotomy, diffuse retroperitoneal lymph node enlargement and metastatic liver nodules were seen. Lymph node and liver biopsy specimens showed diffuse infiltration by abnormal large lymphocytes, which bore monoclonal surface immunoglobulin M and light chain kappa. Only six cases of non-Hodgkin's lymphoma associated with HCL have been published to date. This report describes an additional case of immunoblastic B-cell lymphoma, preceded 4 years earlier by the diagnosis of HCL.

Bone marrow biopsies and smears were examined from 70 patients with acquired immunodeficiency syndrome (AIDS) or AIDS related conditions: 32 patients with AIDS; 9, at risk, group patients with B-cell lymphoma; 22 patients with AIDS related complex (ARC) and 7, at risk, group patients with idiopathic thrombocytopenic purpura (ITP). The first three groups showed similarity with respect to frequency of nonspecific findings: hypo and hypercellularity, marrow damage, lymphoid aggregates, histiocytosis, plasmacytosis and features of myelodysplasia. AFB and fungal organisms were present in the biopsies of 17 per cent of AIDS and 18 per cent of ARC patients. The organisms were associated with bone marrow granulomas or histiocytosis, peripheral lymphopenia and anemia. Only one out of 9 biopsies in patients with previous diagnoses of lymphoma showed involvement of the marrow. One case each of Hodgkin's disease and non-Hodgkin's lymphoma were discovered incidentally among the 22 biopsies from ARC patients without a previous diagnosis of lymphoma. Except for those presenting with ITP alone, bone marrow changes are similar in patients with AIDS and AIDS related conditions.

Ten patients with non-Hodgkin's lymphomas (NHL), six untreated and four with previous chemotherapy, were treated with TA-077, a new derivative of nitrosourea. Partial remission was observed in three untreated cases (30%) of NHL [Case 1: 71-year-old female with B cell lymphoma/diffuse small cell type, Case 2: 79-year-old male with T cell lymphoma/diffuse large cell type, and Case 3: 64-year-old female with adult T cell leukemia lymphoma (ATLL)]. Remission durations were as follows: Case 1; 33 days, Case 2; 38 days and Case 3; 14 days. Side effects were transient anorexia (40%), nausea & vomiting (30%), liver dysfunction (10%) and delayed hematological toxicities (80%). Hematological toxicities consisted of leukocytopenia (80%), thrombocytopenia (60%) and anemia (20%). Our study suggests that TA-077 is a useful agent as one of the drugs used in combination chemotherapy against NHL, since it was effective for refractory T cell malignancies such as ATLL.

Linear IgA dermatosis is a malignancy associated rare bullous disorder similar to dermatitis herpetiformis. Linear IgA dermatosis differs from dermatitis herpetiformis in that the IgA deposits in the epidermal basement membrane are linear rather than granular. A patient is presented with coeliac disease who presented with linear IgA dermatosis and anaemia caused by chronic low grade B cell lymphoma.

We have previously reported that 3'-azido 3'-deoxythymidine (AZT) can possess a significant antineoplastic activity when combined with drugs that disrupt de novo thymidylate synthesis, such as 5-fluorouracil and methotrexate (MTX). The aim of the present study was to evaluate the efficacy and the tolerance of the combination AZT + MTX in human immunodeficiency virus (HIV)-related non-Hodgkin's lymphoma (NHL). Twenty-nine patients (22 men and 7 women), either newly diagnosed or pretreated, have been enrolled in the trial; the median age was 34 years, 45% had acquired immunodeficiency syndrome before lymphoma and 19 patients had less than 100 CD4 lymphocytes/microL. Histologic diagnoses were mainly Burkitt (27%) and diffuse large B-cell lymphoma (45%); extranodal involvement was present in 20 patients. The treatment plan included three weekly courses of MTX at 1 g/m2 (days 1, 8, and 15) plus oral AZT at 2 g/m2 (days 1, 2, and 3), 4 g/m2 (days 8, 9, and 10), and 6 g/m2 (days 15, 16, and 17), plus leucovorin rescue. From the eleventh patient on, in case of complete or partial remission, the treatment was continued with three additional courses, using AZT at the maximum dose. In 26 evaluable patients, the total (complete + partial) response rate was 77% (95% confidence interval, 58% to 89%), with complete remission (CR) in 46% of the patients (95% confidence interval, 29% to 65%). The median CR duration was 12.8 months. Grade III-IV neutropenia and anemia were observed in 52% and 31% of the courses, respectively. There was one therapy-related death due to bacteremia followed by septic shock; the only other recorded infection was a herpes vaginalis. In conclusion, we suggest that AZT + MTX is an effective and well-tolerated regimen in HIV-related NHL.

A 68 year old woman was hospitalized because of cervical lymphadenopathy. Hematological data on admission showed anemia, leukopenia with a normal platelet count. Serum serological studies revealed polyclonal hypergammaglobulinemia, a positive microsome and thyroid test, and positive reaction to antithyroglobulin antibody. Microscopic examination of a cervical lymph node revealed malignant lymphoma, diffuse large cells of B cell phenotype. The bone marrow smears revealed hypercellularity with dysplastic features including pseudo-Pelger and other nuclear abnormalities of neutrophils, micromegakaryocytes, dyserythropoiesis with megalobastic changes, 60% ring sideroblast and with no increase in proportion of blast cells (3.6%). A diagnosis of myelodysplastic syndrome (MDS, refractory anemia with ring sideroblast (RARS)) was made. Remission of ML obtained with radiation and subsequent systemic chemotherapy with CHOP-Bleo regimen, although she died 2.5 yr after the diagnosis due to relapse of ML without leukemic transformation of MDS. Although basic disturbances in these three conditions are not clear, it is evident that treatment was not concerned with the pathogenesis in this case, because the three conditions existed without treatment. It may be hypothesized that an initial event which selects a clone of stem cells that retains the capacity to differentiate into myeloid and lymphoid line would manifest with the features of RARS in the myeloid line and with the sort of immunological abnormalities reported in this case. Subsequent events select subclones and these progressively lose terminal differentiation, culminating as B-cell lymphoma.

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.
