143 patients with non-Hodgkin lymphoma (NHL) at the onset entered this perspective study on NHL-associated risk factors. They were 87 males and 56 females with a mean age of 52.3 years (range 14.6-82.3). An associated hepatitis C virus (HCV) infection was found in 16 of the 143 NHL cases (11.2%; 95% CI 6.5-17.5). They were 11 males and 5 females [mean age 59.9] year with disseminated (13/16) or localized NHL disease (3/16)]. The NHL histological subgroup was low grade (6/16), intermediate grade (2/16) or high grade (8/16). The cell origin was B in 15/16 cases and B cell-T cell rich in 1/16. The discovery of HCV infection was contemporary to lymphoma diagnosis in 6/16 cases but preceded the NHL onset in the other 10 patients. In these 10 patients the median time between HCV infection diagnosis and NHL onset was 3.6 years (range 1-14.5). These data confirm that in Italy the prevalence of HCV infection in patients with NHL (11.2%) is significantly higher than expected in the general population (1.3-3.2%). The finding that, in most cases, HCV infection was definitely antecedent to NHL onset, usually by years, adds evidence to the possible causative role of the HCV in lymphomagenesis.
[Chronic lymphatic leukemia and large granular lymphocytes]

Chronic large granular lymphocyte leukemia is a rather rare disorder (less than 5% of LLC). Its subtype CD3+/CD8+ is often a clonal disease and without malignant characteristics. This kind of disease shows a clinical and laboratory heterogeneity, probably due to the immunological and functional variety of granular lymphocytes. In some cases of LGL leukemia an associated pathology, especially rheumatoid arthritis and chronic infections, has been reported. On the contrary, the relationship with neoplasms has been rarely proved in literature: only occasional studies have been reported and anyway they are not supported by a sufficient number of cases. Two cases of LGL leukemia are here delineated: a woman with advanced breast adenocarcinoma and another one with Sjogren disease. The first one had a rapidly fatal course, while the other one had a prolonged clinical course with chronic neutropenia (13 years follow-up). The association between carcinoma and LGL leukemia may be just a casual finding but the hypothesis of a possible relationship is however very interesting on account of the important role of granular lymphocytes in controlling tumoral growth. Moreover, both patients had concomitant chronic HCV-correlated infection: maybe it will worth making a prevalence study with a greater number of cases, in order to evaluate a probable relationship between these pathologies. The growth factor G-CSF may be useful in the treatment of infections that often occur in patients with severe neutropenia.

We describe a case of MALT (mucosa-associated lymphoid tissue) lymphoma associated to post-hepatitis C liver cirrhosis, type II cryoglobulinaemia, gastrointestinal bleedings and thromboses. HCV infection justified the association between the first three pathologies, while gastrointestinal bleedings and thromboses were respectively attributed to portal hypertension secondary to liver cirrhosis and to some thrombophilic conditions. Among the latter there was also an antithrombin III deficiency. The singularity of the case and some difficulties met in its treatment, justify the report.
[Post-infantile giant cell hepatitis. Clinical and histological response to immunosuppressive therapy]

Giant cell transformation of hepatocytes combined with variable degrees of hepatocyte necrosis and liver fibrosis is distinctly uncommon in adults. In this age group it has most often been associated with autoimmunity, drug reaction and viral infection. Prognosis is considered quite severe ranging from mild fibrosis to established cirrhosis. We report a case of giant cell hepatitis that occurred in a 30 yrs old man, who had been taking ticlopidine for 3 years. The causative role of the drug is uncertain because aminotransferase did not fall after withdrawal. The patient fulfilled most of the criteria for a diagnosis of autoimmune hepatitis and was treated accordingly with prednisolone and azathioprine. Immunosuppressive therapy led to a clinical, biochemical and histological response.
