Primary Hepatic Diffuse Large B-Cell Lymphoma in a Patient with Chronic Hepatitis C
Division of Clinical Pathology, University Hospital, Geneva, Switzerland.American Journal of Surgical Pathology (Impact Factor: 5.15). 10/1999; 23(9):1124-30. DOI: 10.1097/00000478-199909000-00017
Epidemiological and experimental data suggest that the hepatitis C virus infection might be associated with the development of distinct types of non-Hodgkin's lymphomas. Here, we report a case of a patient with chronic hepatitis C and type II mixed cryoglobulinemia, who developed a primary hepatic non-Hodgkin's B-cell lymphoma. A diffuse, large B-cell lymphoma was diagnosed based on morphological, immunophenotypical and molecular genetic findings. Hepatitis C virus replication, as evaluated by strand-specific reverse transcriptase-polymerase chain reaction, was detected in the nonneoplastic liver, but not in the lymphomatous tissue. High grade non-Hodgkin's lymphomas, although rare complications, have to be considered as part of the spectrum of hepatitis C virus-related hepatic lesions.

ABSTRACT: In order to gain further insight into the mechanisms of calcium (Ca) homeostasis in hypercalciuria, we studied 32 lithiasic patients who were divided into three groups: normocalciuric patients (NC; n = 11), patients with absorptive hypercalciuria (AH; n = 12) and patients with renal hypercalciuria (RH; n = 9). The patients were investigated on 3 occasions: during a random diet, after a Ca-restricted diet and during a Ca tolerance test. The following determinations were made: Ca intake, Ca tubular reabsorption (Ca TR), plasma 1,25-dihydroxyvitamin D [1,25(OH)2D] and parathyroid hormone (PTH) levels, natriuresis and urinary protein-bound Gla. The latter was measured as a marker of urinary nephrocalcin excretion. Ca TR was decreased in hypercalciuric patients (HC). AH but not RH patients normalized their Ca TR during fasting. Plasma PTH and 1,25(OH)2D levels were similar in all the groups on the 3 occasions. Natriuresis was elevated in RH during the fasting period (p < 0.02 vs. AH). Compared with NC, protein-bound Gla urinary excretion rates (UER) were enhanced in AH after the Ca-restricted period (p < 0.02) and in RH during fasting (p < 0.02). In AH, a strong positive correlation was found between Ca TR and protein-bound Gla UER (r = 0.79, p = 0.002) following a Ca-restricted diet. In the HC group as a whole, fasting protein-bound Gla UER were correlated to plasma 1,25(OH)2D levels (r = 0.68, p < 0.001). In conclusion, the results suggest that PTH directly or indirectly through 1,25(OH)2D increases nephrocalcin synthesis.(ABSTRACT TRUNCATED AT 250 WORDS)Mineral and Electrolyte Metabolism 01/1993; 19(6):377-84.

ABSTRACT: Epidemiologic data presented in this review suggest the involvement of hepatitis C virus (HCV) in the patho- genesis of some histotypes of B-cell non-Hodgkin's lymphoma, in particular immunocytoma and lymphomas growing primarily in the liver and major salivary glands. Experimental data further support this hypothesis. Recent findings include demonstration that patients with hematologic malignancies can be treated safely with standard and high-dose chemotherapy even in the presence of HCV infection.Current Oncology Reports 04/2000; 2(2):172-5.

ABSTRACT: Primary angiosarcoma of the liver accounts for up to 2% of all primary liver tumors and is the second most common primary malignant neoplasm of the liver. Approximately 10 to 20 new cases are diagnosed every year in the United States and the prevalence varies from 0.14 to 0.25 per million. In an autopsy series from Chicago, one hepatic angiosarcoma was noted for every 30 cases of hepatocellular carcinoma.Clinics in Liver Disease 03/2001; 5(1):219-57, viii.
