Bilateral pulmonary nodules and mediastinal lymphadenopathy in a patient with Sjogren's syndrome
Abstract:
Bronchus-associated lymphoid tissue is a normal component of the lung's immune system and may be analogous to gut-associated lymphoid tissue, a form of mucosa-associated lymphoid tissue. Bronchial-associated lymphoid tissue lymphoma is a distinct subgroup of low-grade B-cell extranodal non-Hodgkin lymphoma, classified as marginal-zone lymphoma. It is a rare disorder and appears with a distinct clinical and radiological presentation. We report a case of a patient with a history of Sjogren's syndrome who presented with bilateral pulmonary nodules and mediastinal lymphadenopathy, and who was diagnosed as having bronchus-associated lymphoid tissue lymphoma.
