ABSTRACT

We have read with great interest in the article by Wang, et al on the higher incidence of non-Hodgkin lymphoma (NHL) in patients with primary Sjögren syndrome (pSS) and the higher incidence of pSS in patients with NHL¹ Thank you for the discovery of the bilateral relationship between pSS and NHL in this nationwide population-based study¹.
