Clinicopathological characteristics of lymphoproliferative disorders in 232 patients with rheumatoid arthritis in Japan: A retrospective, multicenter, descriptive study

Abstract

LPD occurred mainly in methotrexate users, while RA disease activity did not seem to be associated with LPD development. Although the clinical manifestations vary among pathological subtypes, manifestations of LPD in patients with RA can include lymphadenopathy, extranodal mass, and mucocutaneous ulcer.
