A case of primary lymphoma of the liver in a patient with acquired immunodeficiency syndrome (AIDS) is presented. Persistent fever, tender hepatomegaly, and mildly abnormal liver function tests combined with an elevated lactate dehydrogenase level gave the clue for the diagnosis. High-grade, non-Hodgkin's lymphoma of B-cell phenotype was demonstrated by percutaneous liver biopsy. Primary hepatic lymphoma is a rare event among patients with AIDS. We reviewed the cases in the literature and noted that a preponderance of these patients presented with multiple lesions (a rather rare occurrence in primary lymphoma of the liver in patients not infected with the human immunodeficiency virus).

We studied 14 adult patients presenting with fever and cytopenia of the peripheral blood and histiocytic hyperplasia with hemophagocytosis (HHH) in the bone marrow regarding an association of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) by using in situ hybridization (ISH) and also evaluated the clinical and laboratory findings according to the encountered organisms. ISH using a CMV RNA probe demonstrated infected cells in 6 out of 14 cases (43%), and ISH using an EBV EBER RNA probe demonstrated infected nuclei in 5 out of the same 14 cases (36%) of HHH. No cases showed a positive reaction with both probes. Three cases showed a negative reaction with both probes. The mean age of all patients was 29 years; and that of the CMV-positive patients was 27 years and that of the EBV-positive patients was 36 years. Organomegaly was found in 3 out of 6 CMV-positive patients (1 hepatomegaly, 1 splenomegaly, 1 hepatosplenomegaly), and 4 out of 5 EBV-positive patients (lymphadenopathy in all 4 cases, hepatosplenomegaly in 2 cases). One of the CMV-positive case had acute myeloblastic leukemia, and 2 EBV-positive cases had underlying malignancy (1 Hodgkin's disease, 1 non-Hodgkin's lymphoma). Seven out of the 14 HHH cases (50%) died within several months after diagnosis. Nucleic acid hybridization methods can be used for the routine examination of the association of CMV or EBV.

We examined 111 patients with acute type- or lymphoma type-adult T-cell leukemia (ATL) and compared them with 106 patients with non-Hodgkin's lymphoma (NHL). In addition to skin involvement and hypercalcemia which are already known to be frequent in ATL, ATL patients showed an higher incidence of hepatic involvement. There was more frequent palpable hepatomegaly, higher total bilirubin, GOT, GPT, lactate dehydrogenase (LDH), and alkaline phosphatase values in ATL than in NHL patients (p < 0.0001). Among 36 autopsied liver samples, invasion of ATL cells was confirmed in 22 cases. ATL patients with impaired hepatic function showed shorter survival times than patients without hepatic dysfunction. Moreover, ATL patients showed a worse performance status (PS), a higher incidence of lytic bone lesions, lower total protein (TP) and serum albumin levels than NHL patients. This invasive characters of ATL cells and consequent impaired general condition seemed to be factors affecting the poor prognosis recorded in ATL.

This paper describes a rare occurrence of primary lymphoma of the liver in a young female and demonstrates the possibility of making the correct diagnosis by ultrasonically guided fine needle aspiration biopsy. A 32-year old female suffering from upper abdominal pain, hepatomegaly, nausea, anorexia and weight loss for almost 2 months was admitted to our Department. After a clinical and instrumental (lab exams, ultrasonography, computed tomography) evaluation, we reached the correct diagnosis of hepatic primary non-Hodgkin's lymphoma by means of ultrasonically guided fine needle aspiration biopsy. Two weeks after hospitalization the patient was treated with 8 cycles of CHOP chemotherapy and then with alpha-2b interferon immunotherapy. The hepatic ultrasonography and CT abdominal scan showed the complete absence of the lymphomatous lesions 36 months later. Up to February 1998, the patient was well and led a normal life. We conclude that the CHOP chemotherapy plus interferon immunotherapy were effective and well tolerated with a complete response 38 months following diagnosis.

The incidence and pattern of liver involvement in 127 liver specimens (2 biopsy and 125 autopsy specimens) from cases of acute myelogenous leukaemia (25), chronic myelogenous leukaemia (7), acute lymphatic leukaemia (5), chronic lymphatic leukaemia (9), multiple myeloma (25), low-grade non-Hodgkin's lymphoma (25), high-grade non-Hodgkin's lymphoma (24) and myeloproliferative diseases (7) were investigated histologically and immunohistochemically. Liver infiltration was found frequently in chronic leukaemia and myeloproliferative diseases (80-100%), acute leukaemia (60-70%) and non-Hodgkin's lymphoma (50-60%), but was significantly less common in multiple myeloma (32%) than in any of the other diagnostic groups. Hepatomegaly was found in over 50% of cases in all the diagnostic groups, but was not always associated with infiltration. Diffuse, non-destructive infiltration was most common: in acute myelogenous leukaemia, both the portal triads and sinusoids were usually involved; in chronic myelogenous leukaemia, multiple myeloma and myeloproliferative diseases, infiltration was mainly sinusoidal; and in lymphatic leukaemia and non-Hodgkin's lymphoma the portal triads were mainly involved. Nodular infiltration was seen in multiple myeloma and non-Hodgkin's lymphoma. The primary tumours and liver infiltrates generally exhibited the same immunophenotype, although reactivity with the antibody L26 (CD20) was only found in the primary lesion in many high-grade B-cell lymphomas. Thus, liver involvement is common in haematological malignancies, but the incidence and pattern of infiltration vary amongst the different types.

We report a case of non-Hodgkin's lymphoma (NHL) presenting with acute renal failure. A-56-year-old male was admitted to our hospital on October, 1997 with fever and renal dysfunction. Physical examination showed no abnormality except for hepatomegaly. Body surface lymphadenopathy was not observed. Computed tomography (CT) of the abdomen showed markedly enlarged kidneys bilaterally and a mass of soft tissue density, which was considered as a swelling lymph node, around the aortic artery. The renal biopsy revealed parenchymal involvement of the NHL cells without normal tubulo-interstitial structure, but the glomeruli were almost intact. Our case rapidly fell into oliguria and acute renal failure, hence needed hemodialysis. After chemotherapy was performed, his renal function gradually improved and the kidney became smaller on subsequent CT. Unfortunately, the patient happened to suffer from methicillin-resistant staphylococcus aureus (MRSA) infection in a neutropenic state and died. Necropsy revealed recovery of the renal interstitium without residual NHL cells. Renal lymphoma without any other organ or nodal involvement is a rare type of NHL, which considered primary renal lymphoma (PRL). However, we believe this case to have been a result of lymphomatous infiltration of the kidneys in disseminated lymphoma.

T-cell-rich B-cell lymphoma (TCRBCL) is a recently recognized and ill-defined form of non-Hodgkin's lymphoma (NHL), with no generally accepted diagnostic criteria and with limited information regarding its incidence, cellular origin, morphologic spectrum and biologic behavior. The recent findings suggest that TCRBCL could be a biologically distinct disease characterized by male preponderance, advanced-stage disease initially and high incidence of extranodal localization, especially in the bone marrow. For the time being, proper diagnosis rests on the immunohistochemical identification of the scattered large malignant B-cells amid a sea of small reactive T-lymphocytes. In this study, the clinicopathologic features of 8 patients (pts) with TCRBCL are presented. The male to female ratio was 5/3, and the median age was 52 years (32-67). The disease was advanced in most patients: 5 pts with stage IV and 2 pts with stage III. The patients presented with generalized lymphadenopathy (5), splenomegaly and/or hepatomegaly (4) and bone marrow involvement (4). The diagnosis of TCRBCL was initially established in 6 pts, while the remaining 2 pts were initially diagnosed as having Hodgkin's disease (of mixed cellularity in 1 pt and lymphocytic predominance in another). Revision of the 2 samples comprising immunohistochemistry enabled diagnosis of TCRBCL. Immunohistomorphologically the present series can be differentiated from other types of lymphoma such as lymphocyte-predominant Hodgkin's disease and peripheral T-cell lymphoma.

We report on a case of CD20-positive peripheral T cell lymphoma. The lymphoma cell was positive for CD20 and T cell lineage markers such as cytoplasmic CD3, CD4, and CD5 and had a monoclonal rearrangement of the T cell receptor (TCR) gamma chain gene. The clinical characteristics resembled angioimmunoblastic lymphadenopathy: spontaneous regression of lymphadenopathy and immunological abnormalities such as polyclonal hypergammaglobulinemia, positive results of direct and indirect antiglobulin tests, and a high antinuclear antibody titer. We reviewed seven cases of CD20-positive T cell malignancies including the present case. Three were immature T cell malignancies (acute lymphoblastic leukemia) and four were peripheral T cell malignancies (non-Hodgkin's lymphoma and chronic lymphocytic leukemia). Hepatomegaly and/or splenomegaly were common features. Further cases must be evaluated to understand the clinical significance of the CD20 expression on the surface of T cell malignancies.

We report two patients with isolated bone marrow non-Hodgkin's lymphoma and we review the additional 23 cases thus far described. Bicytopenia or pancytopenia and an elevated erythrocyte sedimentation rate were universally present. Some 84% of the patients manifested fever of unknown origin (FUO), 64% constitutional symptoms, 48% hepatomegaly, and 52% splenomegaly. Of the variety of therapeutic protocols used, corticosteroids, alone or in combination, appeared to be the most effective. Survival ranged from 1 week to 4.5 years. Early diagnosis would avoid unnecessary work-up in patients with FUO and enable optimization of therapy.

We review the literature on primary hepatic lymphoma (PHL). PHL is a rare malignancy, and constitutes about 0.016% of all cases of non-Hodgkin's lymphoma. It has been reported to occur with increased frequency in patients with chronic hepatitis C infection. Most patients with PHL present with abdominal pain, constitutional symptoms and have hepatomegaly on examination. Imaging studies reveal solitary, or less often, multiple masses in the liver. The predominant histology is B-cell lymphoma, most commonly diffuse large cell type. Most patients are treated with chemotherapy, with some physicians employing a multimodality approach incorporating surgery and radiotherapy with chemotherapy. The prognosis is variable, with good response to early aggressive combination chemotherapy.
