In order to determine the frequency and characteristics of patients with liver abnormalities as the presenting manifestation of Hodgkin's disease (HD), 421 consecutive HD patients were studied. Six patients in the series (1.4%) presented with liver abnormalities that led to of a liver biopsy and the subsequent diagnosis of HD. All had fever prior to HD diagnosis, four frank jaundice, and one hepatic failure. No patient had pruritus. Moderate hepatomegaly was present in four patients. Cholestasis was observed in all cases; in most patients a moderate increase in the transaminase activity was also seen. Two patients had a mild rise in the serum LDH, four had leukopenia, and one eosinophilia. At liver histologic study, Reed-Sternberg cells were demonstrated in four patients; in the remaining two, the presence of atypical histiocytes, lymphocytes, and eosinophils was highly suggestive of HD, the latter diagnosis being confirmed by subsequent study of bone marrow and/or retroperitoneal lymphadenopathies. In three of the six patients, HD was not demonstrated in sites other than the liver. Three patients older than 60 years died shortly after HD diagnosis. By contrast, three patients younger than 40 years showed a dramatic response to chemotherapy: two of them had a further relapse, and one is considered cured after 14 years of continuous remission. Liver disease constitutes an infrequent form of HD presentation which must be included in the differential diagnosis of any patient with fever of unknown origin.

The effects of silty clay loam soil on the performance and biochemical parameters of chicks were investigated when the soil was added to aflatoxin B1 (AFB1)-contaminated diets. One hundred 14-d-old White Leghorn chicks were fed a control ration (clean corn), a low aflatoxin-contaminated ration (120 ng AFB1/g), a high aflatoxin-contaminated ration (700 ng AFB1/g), or high aflatoxin-contaminated rations (700 ng AFB1/g) +10% or 25% soil. Body weight, feed consumption and blood samples were monitored weekly. Decreased feed consumption, body weight gain and efficiency of feed utilization, increased SGOT and LDH activities, and cholesterol and triglyceride concentrations, and decreased uric acid concentrations and ALP activity were observed in the chicks fed the high aflatoxin-contaminated ration without soil. Hepatomegaly was prominent in chicks fed the high aflatoxin-contaminated ration without soil, and some livers had extensive hepatocyte vacuolation, hepatocellular swelling, fatty change and hydropic degeneration, and stained positive for fat accumulation. Addition of soil reduced the detrimental effects of AFB1 for some parameters, although the reduction was less when 10% soil was fed compared with the 25% soil feeding.

We report on a 43-year-old man with a primary sarcoma of the liver. The patient was admitted to the hospital for evaluation of dyspnea, abdominal pain in the right upper quadrant, diarrhea, and fever. Physical examination revealed hepatomegaly. Increased laboratory values were found for gamma-GT, LDH, CA 125, and NSE, but not for aspartate and alanine aminotransferase. Computed tomography presented a tumor in the right lobe of the liver. Venous cavography revealed a caval tumor thrombus reaching up to the right atrium. Major liver resection combined with replacement of the vena cava inferior was proposed, but before operation the patient complained about shortness of breath. Spontaneous fragmentation of the tumor thrombus with consecutive embolization of the lungs was suspected. Despite lysis therapy the patient died because of right ventricular failure. Autopsy revealed a tumor measuring 8 cm in diameter, which was located in the right lobe of the liver and invaded the inferior vena cava. Because of multiple tumor aggregates seen in the left and right main pulmonary arteries acute tumor embolization of the lungs was regarded as cause of death. Histologically the tumor was composed of bizarre giant cells surrounded by irregular spindle cells. The positive immunoreactivity pattern of the tumor cells for vimentin, lysozym, and CD68 justified the diagnosis of a malignant fibrous histocytoma (MFH) of the liver.

Several authors have tried to solve the problems in the classification of CMML. A fully suitable classification does not exist. The goal of our study was to determine common and different signs of MD and MP type of CMML and to observe frequency of shifts from MD to MP-CMML. Sixty nine CMML patients were divided according to FAB proposal into two groups: 31 patients into the MD group (WBC < or = 13 x 10(9)/l) and 38 patients into the MP group (WBC < or = 13 x 10(9)/l). Presenting features and the course of the disease in both groups were evaluated. The median age of patients was not different in both groups (71.5 and 74 years, respectively), male/female ratio was 1.1 and 2.4, respectively. The median follow-up time was 15.5 months (1-58.8) in MP group and 24 months (2-118) in MD group. In MP group splenomegaly, hepatomegaly, lymphadenopathy, abnormal karyotype and skin involvement were found more often than in MD group. Median LDH value was higher in MP group. Probability of survival was higher in the MD group than in MP group (median 30 and 11 months, respectively). Leukaemia transformation frequency was similar in both groups. In 12 out of 24 (50%) MD group patients WBC increased during the course of the disease over 13 x 10(9)/l. Oscillation of WBC values below and over 13 x 10(9)/l was observed in three patients. During the follow-up time number of patients with splenomegaly and/or immature granulocytes in the PB increased. After inclusion of 12 patients who shifted from MD to MP group a new CMML group resulted characterised by longer median survival (17 months) due to a higher number of patients in an earlier stage of the disease. Failure of evolution of myeloproliferative signs and lower frequency of AL in the remaining group might be explained by an early stage of CMML, untimely deaths due to unrelated causes and/or by patients suffering of RA with monocytosis rather than of CMML. In summary, our data suggest, that evolution from MD-CMML to MP-CMML is a frequent event and that MD-CMML could be the early stage of CMML in most of cases. The WBC at diagnosis as the single criterion for subclassification of CMML does not seem to be fully justified. We propose that CMML should not be divided in MD and MP types and that monitoring of patients and search for other signs of myeloproliferation such as PB immature granulocytes, splenomegaly, lymphadenopathy, skin involvement, pleural or peritoneal effusions, spontaneous growth of CFU-GM in vitro should be taken in consideration for a better classification of CMML, which would have an impact on the therapeutic approach.

An increase of angiogenesis has been shown in idiopathic myelofibrosis with myeloid metaplasia (MMM) by microvessel density count method but evaluation of circulating angiogenic factors is still incomplete. In 31 patients affected by MMM and in 12 healthy subjects we evaluated the serum levels of VEGF (vascular endothelial growth factor) and correlated VEGF with clinical and laboratory features of disease. We found that MMM patients had circulating VEGF concentrations much higher than controls (Median 1208 ng/ml vs 138 ng/ml, P < 0.0001). No correlation was found between VEGF and Hb, WBC, PLT, LDH, creatinine, bone marrow cellularity, fibrosis, splenomegaly, hepatomegaly, and therapy. However, in the subgroup of patients with a normal or low VEGF concentration, a direct correlation between VEGF and platelet count (r = 0.90, P = 0.002) was detected. Moreover, patients with a platelet count < 300 x 10(9)/l had VEGF serum levels lower than patients with a higher PLT count (median VEGF 864 vs 1557 pg/ml, P = 0.001). In six patients and in eight controls we also had the opportunity to measure VEGF in the plasma and we calculated that VEGF concentration was much higher in platelet-rich than in platelet-poor plasma and that platetets of MMM patients contained four times more VEGF than those of healthy controls. These results indicate that VEGF is overproduced in MMM, thus confirming an increased angiogenic activity. Platelets are probably a major source of VEGF in MMM but not the only one.

We report a case of a 52-year-old male who developed classical Hodgkin's lymphoma (HL) four years after diagnosis of stage Rai II (Binet B) chronic lymphocytic leukemia (CLL). The patient was treated with fludarabine and cyclophosphamide with partial response. Subsequently, he presented with a 6-month history of weight loss and fatigue, and 6 weeks of fever, a progressively enlarged liver and elevated serum LDH level. An inguinal lymph node biopsy revealed both classical Hodgkin's lymphoma, nodular sclerosing type grade 2 and CLL. A bone marrow biopsy showed no Reed-Steinberg cells and an infiltrate composed of only scattered small lymphocytes consistent with CLL. Immuno-histochemical studies of the lymph node were consistent with both CLL and HL phenotypes. A cytogenic examination of the bone marrow revealed an abnormal karyotype (Y-) in 15% of the cell population. Treatment with MOPP/ABVD was started and fever subsided within 3 days. Our case is one of the very few descriptions of a rare Richter's variant of CLL with progression to HL in a CLL patient treated with fludarabine. Since fludarabine has become standard therapy in CLL such Richter's variant could be the result of therapy, an induced prolonged and severe immunosuppression. Clinicians should be aware of such association, which could become more frequent among CLL patients treated with purine analogs.

Lymphomas secondarily involving the breast are uncommon, although they do represent the largest group of tumors metastatic to breast. A 20-year-old female with lymphoblastic lymphoma (LBL) presented here with 3 month history of weight loss, night sweats, fatigue and a mass in her left breast. Her physical examination revealed a left breast mass, lympadenopathy, bilateral pleural effusion and hepatomegaly. WBC count was 17,710/mm3 and LDH was mildly elevated. Breast ultrasound showed a 1.7 cm mass in the inner lower quadrant of left breast. Biopsy of the breast mass showed diffuse infiltration with small, round atypical cells which did not stain with CD20, CD43, CD34, cytokeratine and were positive for CD3. She was diagnosed as leukemic phase of a precursor T-cell LBL and treated with 6 cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone), intrathecal methotrexate and cranial radiotherapy, achieving a complete response. She then was started on maintenance therapy. Four months later she returned with CNS involvement and was started on induction treatment. She had a very aggressive course of disease and died only 12 months after diagnosis. Breast involvement is very rarely seen in precursor T-cell LBL/ALL and in this patient occurred secondarily as part of widespread disease.

Transplantation-associated thrombotic microangiopathy has been associated with significantly reduced survival following allogeneic bone marrow transplantation. We describe here the course of Transplantation-associated thrombotic microangiopathy and hepatic veno-occlusive disease, and response to plasma exchange therapy. A 19-year-old male patient underwent hematopoietic stem cell transplantation (HSCT) from his HLA-matched brother for lymphoblastic lymphoma in the first complete remission. Transplantation-associated thrombotic microangiopathy was diagnosed 17 days after transplantation. At that time, neurological abnormalities were not present. Cyclosporin A (CsA) was discontinued. Hematological stabilization was recorded. On day +20, abdominal distention, painful hepatomegaly and ascites complicated the clinical picture. With a high hepatic venous pressure gradient (18mmH20), veno-occlusive disease of the liver was diagnosed and defibrotide was started, which resulted in a dramatic cessation of pain and increase in urinary output. However, transplantation-associated thrombotic microangiopathy-related symptoms progressed and plasma exchange was instituted, which resulted in worsening of veno-occlusive disease symptoms. He was referred to the Intensive Care Unit due to respiratory compromise and was intubated. Plasma exchange was continued in order after hemofiltration. In three days, fever resolved, hemofiltration could be stopped, and ventilator dependence ended. After 19 aphereses, serum LDH level returned to normal and schistocytes were minimal on microscopic examination of the blood film. Platelet count increase was more gradual. Plasma exchange was discontinued. On the 40th day of defibrotide, all symptoms related with veno-occlusive disease were resolved and defibrotide was stopped. We think that our case is important to establish the relation and management strategy of these two small vessel complications of HSCT.

There is controversy over whether to scan extrathoracic sites for metastases in patients with non-small cell lung cancer (NSCLC). We tested the efficiency of clinical factors to determine whether metastasis has occurred, and whether routine scanning for NSCLC is required. Nine hundred and forty five patients scanned for extrathoracic metasates were included. Clinical factors indicating metastasis were determined using multivariate analysis. Of the 945 cases, 377 (39.9%) had metastasis. Bone metastases were determined by focal skeleton pains, elevated serum alkaline phosphatase levels, adenocarcinoma, KPS</=70, sensitivity of 90.6, specificity of 12.7, PPV of 16.3, NPV of 87.8, and silent metastases rate (SMR) of 9.4%. Brain metastases were determined by neurological symptoms, adenocarcinoma, hematocrite <40 for men and <35 for women, KPS</=70, sensitivity of 89.9, specificity of 7.9, PPV of 9.2, NPV of 88.3, and SMR of 10.1%. Abdominal metastases were determined by abdominal pain/tension, hepatomegaly, elevated GGT levels, serum LDH levels >500 IU, a N2 or N3 case, KPS</=70, sensitivity of 95.9, specificity of 7.1, PPV of 13.3, NPV of 92.1 and SMR of 4.1%. Of the 224 patients with stage I and II disease, 73 had metastasis with a rate of 10.9% silent metastasis. We concluded that routine scanning of NSCLC for staging is necessary.

Burkitt's lymphoma is a rare disease that belongs to the aggressive non-Hodgkin's lymphoma. Herein, we report a case of primary hepatic Burkitt's lymphoma. A 19-year-old man visited the hospital for right upper quadrant pain. He felt fatigue for two months. Physical examination revealed hepatomegaly and no palpable lymph node. He had no fever, weight loss, or night sweating. Laboratory finding showed mild anemia (hemoglobin, 12.4 g/dL), mild elevated transaminase (ALT, 52 IU/L), elevated lactate dehydrogenase (LDH, 437 IU/L), and alkaline phosphatase (ALP, 129 IU/L). The viral marker was positive for HBsAg, HBeAg, anti-HBs, and anti-HBc (IgG), and negative for anti-HBe, anti-HCV, and anti-HIV. CEA, AFP, and CA19-9 levels were within normal ranges. The HBV DNA quantitation was 1.3 x 10(9) copies/ml. Abdominal-Pelvis CT scan and abdominal MRI finding were compatible with malignant lymphoma. Liver biopsy examination confirmed Burkitt's lymphoma. No metastasis was detected in the thoracic cavity, bone marrow, and spinal fluid. The patient was treated with the combination regimen of cyclophosphamide, doxorubicin, vincristine, prednisone and high dose methotrexate. Cytosine arabinoside and methotrexate were added for CNS prophylaxis by intrathecal installation. Chemotherapy was administered every 3 weeks for fifteen cycles. Serial follow-up CT scan showed a marked decrease in the size of hepatic lesions. Follow-up CT scan and PET-CT scan were performed 4 weeks after the final cycle disclosed no definite residual or active lesion confirming the state of complete remission.
