[The relationship between Sjogren's syndrome, systemic sclerosis and lymphoproliferative diseases].

Unlabelled: Despite the large number of studies devoted to the study of systemic sclerosis (SSc), the high risk of developing lymphomas in this disease, the relationship of their development with certain subtypes of SSc and specific SSc-associated autoantibodies is still debated in the literature.

Aim: To study demographic, clinical, laboratory and immunological characteristics of patients with a combination of primary Sjogrens syndrome (pSS) and SSc and diagnosed lymphoproliferative diseases (LPDs); to characterize morphological/immunomorphological variants and course of non-Hodgkins lymphomas (NHL), developing in patients with these rheumatic diseases (RDs).

Materials And Methods: In 19982018 at the Nasonova Research Institute of Rheumatology, 13 patients with clinical and laboratory manifestations of pSS (12) and SSc (13) were diagnosed with various lymphoproliferative diseases (LPDs).
