title: Hematologic manifestations of primary Sjögren's syndrome.
abstract: Sjögren's syndrome (SS) is a chronic autoimmune disorder, primarily characterized by the mononuclear cell infiltration of exocrine glands exiting in parenchymal damage and secretory impairment. The spectrum of the disease extends from an autoimmune exocrinopathy to a systemic process with extraglandular manifestations. SS is defined as primary (pSS) when isolated, or secondary when associated with another autoimmune disease. Patients with pSS may present hematologic abnormalities, such as anemia, hemocytopenias, monoclonal gammopathies and lymphoprolipherative disorders, predominantly non-Hodgkin's lymphoma of B-cell origin. The increased prevalence of B-cell malignancies suggests that SS may be a boundary disease between autoimmunity and lymphoproliferation. In this paper, the hematologic manifestations of pSS are reviewed.
