Adult T-cell leukemia/lymphoma (ATLL) is an HTLV-I associated lymphoid malignancy frequently seen in Japan. Abdominal involvement in 40 patients with ATLL were assessed by ultrasonography and the findings seen in four clinical types, acute, chronic, lymphoma and smoldering, were compared. Splenomegaly was frequently found in the cases of acute and lymphoma types, and the sizes of the spleens measured by ultrasonography correlated well with the disease activity. Hepatomegaly was also found more frequently in acute and lymphoma types, and hepatosplenomegaly was proved to be due to the infiltration by ATL cells. Nodular lesions in spleen and liver and abdominal lymph node swelling were also found frequently in the lymphoma type but rarely in the other types. Ascites, pleural effusion, and pericardial effusion were found in the active stage of acute and lymphoma types. Ultransonography also could detect findings associated with therapies. Thus, ultrasonography studies were found to be very useful for assessing the clinical classification, examining various pathological conditions associated with ATLL, and monitoring the disease activity.

Tender hepatomegaly and ascites occurred in a young woman receiving cytosine arabinoside and daunorubicin for acute myelogenous leukemia. Whereas veno-occlusive disease was suspected clinically, liver biopsy showed nodular regenerative hyperplasia with no evidence of hepatic vein abnormalities. It is postulated that nodular regenerative hyperplasia can be initiated by hepatotoxicity of chemotherapy agents used to treat leukemia and/or that these agents exacerbate clinical manifestations of this histological abnormality. Nodular regenerative hyperplasia should be added to the list of liver problems occurring in patients with leukemia.

A 68-year-old woman with Felty's syndrome had massive hepatomegaly. Liver biopsy showed diffuse infiltration of the sinusoids with mature lymphocytes (sinusoidal lymphocytosis of the liver). Nodular regenerative hyperplasia of the liver and portal fibrosis were not found. Although liver involvement is frequent in association with Felty's syndrome, sinusoidal lymphocytosis of the liver is unusual.

Nodular regenerative hyperplasia of the liver developed in five patients who had the toxic oil syndrome caused by ingestion of adulterated cooking oil. This hepatic complication was detected from 19 to 37 months (mean-2.5 years) after the onset of the toxic oil syndrome. Nodular regenerative hyperplasia was asymptomatic, although all patients had persistently abnormal liver function. Hepatomegaly was present in four cases, mild jaundice in three and signs of portal hypertension in two. Pathogenesis of nodular regenerative hyperplasia in toxic oil syndrome is unknown, but probably microcirculatory disturbances within the liver might have played a role. Fibrosis in Zone 3, sinusoidal dilatation and occasionally intralobular hemorrhage were seen in three cases; in one of them, characteristic lesions of veno-occlusive disease were also present. In another case, endarteritis changes of hepatic arterioles were evident.

Mastocytosis is a disease of mast cell hyperplasia that may involve several organ systems, including liver. Between 1988 and 1991, we conducted a retrospective-prospective study of 41 patients with mastocytosis and found 61% had evidence of liver disease. Hepatomegaly was detected in 24%, splenomegaly in 41%, and elevated serum alkaline phosphatase, serum aminotransaminases, 5'nucleotidase, or gamma-glutamyltranspeptidase (GGTP) in 54% of the patients. Alkaline phosphatase levels directly correlated with GGTP levels, hepatomegaly, splenomegaly, and liver mast cell infiltration and fibrosis. Elevated alkaline phosphatase levels and splenomegaly were observed more frequently in patients with categories II and III mastocytosis. Five patients in combined disease categories II or III developed ascites or portal hypertension and died of complications of mastocytosis; three had hypoprothrombinemia at the time of death. Thirty-five liver biopsy specimens from 25 patients were examined. Mast cell infiltration was commonly observed in the biopsy specimens, more severe in those patients with either category II or III disease, and correlated with hepatomegaly, splenomegaly, alkaline phosphatase levels, and GGTP levels. Mast cells were often only detected by using special stains (toluidine blue and chloracetate esterase). Increased portal fibrosis was seen in 68% of the biopsy specimens and correlated with mast cell infiltration and portal inflammation. Cirrhosis was not observed. Nodular regenerative hyperplasia, portal venopathy, and venoocclusive disease was observed in eight biopsy specimens and may have been the cause of the portal hypertension or ascites in four patients. These findings demonstrate that liver disease with mast cell infiltration is a common finding in patients with mastocytosis.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Nodular regenerative hyperplasia (NRH) of the liver is an infrequent entity that is usually diagnosed after the appearance of clinical signs of portal hypertension such as hepatomegaly, splenomegaly or upper gastrointestinal bleeding due to esophageal varices, which are the most frequently found clinical manifestations in NRH. Ascites is a less frequent finding and has always been described in association with other manifestations of portal hypertension. We describe a new case of NRH with atypical presentation in which ascites was the sole clinical manifestation.

Patients with common variable immunodeficiency disorders are monitored for liver function test abnormalities. A proportion of patients develop deranged liver function and some also develop hepatomegaly. We investigated the prevalence of abnormalities and types of liver disease, aiming to identify those at risk and determine outcomes. The local primary immunodeficiency database was searched for patients with a common variable immunodeficiency disorder and abnormal liver function and/or a liver biopsy. Patterns of liver dysfunction were determined and biopsies reviewed. A total of 47 of 108 patients had deranged liver function, most commonly raised alkaline phosphatase levels. Twenty-three patients had liver biopsies. Nodular regenerative hyperplasia was found in 13 of 16 with unexplained pathology. These patients were more likely to have other disease-related complications of common variable immunodeficiency disorders, in particular non-coeliac (gluten insensitive) lymphocytic enteropathy. However, five had no symptoms of liver disease and only one died of liver complications. Nodular regenerative hyperplasia is a common complication of common variable immunodeficiency disorders but was rarely complicated by portal hypertension.

Nodular regenerative hyperplasia of the liver -a type of noncirrhotic portal hypertension- is a rare condition of unknown etiopathogenesis that has been associated with multiple disorders, including diverse types of hematologic disease. We report the case of a 36-year-old female patient diagnosed with cutaneous T-cell lymphoma of the mycosis fungoides variety, staged as T2N0M0B0, where a transjugular liver biopsy demonstrated the presence of nodular regenerative hyperplasia with a hepatic venous pressure gradient of 15 mm Hg. The study was triggered by the incidental radiologic finding of hepatomegaly with indirect evidence of portal hypertension. We are not aware of any previous reports on the association of nodular regenerative hyperplasia with mycosis fungoides in the medical literature.
