Malignant lymphoma in primary Sjögren's syndrome: an update on the pathogenesis and treatment.

Objectives: Sjögren's syndrome (SS), a chronic autoimmune disorder, particularly compromises the function of exocrine glands. Its association with lymphoma is well documented. Our aim was to systematically review the molecular, clinical, histopathologic, and therapeutic aspects of these SS-related malignant lymphoproliferations.
