Abstract

Follicular bronchiolitis (FB) is an uncommon pulmonary lymphoproliferative disorder that is characterized by the presence of peribronchiolar hyperplastic lymphoid follicles with reactive germinal centers. FB could be associated with systemic illnesses including immunodeficiency, infection, and autoimmune diseases. In Korea, a single case of FB with rheumatoid arthritis was recently described but there has been no report on FB associated with other rheumatic diseases. Herein, we describe the first case of FB presenting nodular ground-glass opacities (GGO), which mimicked lung cancer, in patients with primary Sjögren's syndrome (SS). The differential diagnosis of nodular GGO lesions should include FB although it is a rare manifestation in SS patients.
