“…This association was first proposed in 1953 (ZATUCHNI et al, 1953) and successively several epidemiological studies have been performed to explore this risk (Chatterjee et al, 2005, Hill et al, 2003, Duncan & Winkelmann, 1979. A number of sporadic case reports have underlined the association between SSc and NHL, particularly with aggressive B-cell subtypes (Arnaud et al, 2006, Derk et al, 2004, Haviv et al, 1997 and some authors observed an increased risk of NHL among SSc patients, primarily within the first year after the onset of disease, but not beyond 4 years of follow up (Landgren et al, 2006, Mellemkjaer et al, 2008, Rosenthal et al, 1993. Conversely, other studies failed to demonstrate a consistent association between SSc and lymphomas (Chatterjee et al, 2005, Rosenthal et al, 1995, Roumm & Medsger, 1985.…”
