Chronic hepatitis C virus infection (CHCV) has high prevalence of immunological abnormalities. Extrahepatic manifestations (EHM) have been reported in association with CHCV infection, whose heterogeneity makes difficult any correlation between the two disorders. Among extrahepatic symptoms of C virus hepatitis, sicca syndrome is also registered. Sjogren's or sicca syndrome (SS) is a chronic, slowly progressive disease, with inflammatory-immune mediation characterized by lymphocytic infiltration of the lachrymal and salivary glands. A distinct primary form and a secondary one, occurring when presented in the context of an autoimmune or hepatic disease have been described. We present a case of SS in a patient with CHCV, commenting a possible link between primary SS and the CHCV, as well as the similarities and the distinctions among these conditions. Our conclusion is that CHCV can induce SS with some clinical particularities like presence of pericapillary and not pericanalicular lymphocytic infiltrate without destroying the salivary glands, in the absence of SS-A/SS-B antibodies. The favorable evolution of SS under IFN therapy is an argument for an authentic relation. Further studies are necessary to determine if CHCV is an etiological agent of SS or of it can induce a pseudo-sicca syndrome, characterized by a simple glandular inflammation consisting mainly in a simple lymphocytic adenitis.
