Mucosa-associated lymphoid tissue lymphoma in Sjögren's syndrome: risks, management, and prognosis.

Sjögren's syndrome is a chronic inflammatory disease primarily affecting the exocrine glands. Its association with lymphoma is well documented, with salivary extranodal marginal zone lymphomas of the mucosa-associated lymphoid tissue type being the most common and constituting a major disease complication. These neoplasms are antigen-stimulated B-cell lymphomas characterized by localized stage, indolent clinical course, and recurrence in other extranodal sites. This article presents a review of the literature and discusses the clinical, histopathologic, therapeutic, and prognostic aspects of these tumors in Sjögren's syndrome. In addition, it highlights the predictor markers of lymphoma development.
