Abstract Chronic infection with hepatitis C virus (HCV) may lead to B cell activation and transformation into non-Hodgkin lymphoma (NHL). Molecular mechanisms of B cell transformation by HCV are poorly understood. One of the most common lymphoproliferative disorders in HCV-infected patients is splenic marginal zone lymphoma (SMZL). A case of a 42-years old man, affected by HCV-related SMZL, effectively treated with an IFN-free, NS3-NS4A inhibitor-based regimen, is hereby described. The patient was treated for 16 weeks with faldaprevir, deleobuvir, and ribavirin, achieving a very rapid viral eradication without relevant toxicities. A rapid haematologic response was noted as well, with a statistically significant correlation between viral decay and lymphocyte improvement (coefficient r = 0.55, p = 0.042). The viral clearance led to SMZL cure, even without the use of IFN. Thus, the causative role, played by HCV in SMZL development, is once again reinforced, whereby the antiviral, rather than the anti-proliferative activity of IFN is indirectly proven. A regimen including DAAs should be considered when treating a HCV-related extra-hepatic disease. Copyright © 2014 European Association for the Study of the Liver. Published by Elsevier B.V.
