Tracheobronchial amyloidosis with Sjögren’s syndrome: a case report
We report a case of tracheobronchial amyloidosis (TBA) in a 55-year-old woman with newly diagnosed primary Sjögren’s syndrome (SS), presenting with persistent cough, hemoptysis, and dry mucosal symptoms. Chest CT showed thickened airway walls and cystic lung changes, while bronchoscopy revealed nodu...

| Summary: | We report a case of tracheobronchial amyloidosis (TBA) in a 55-year-old woman with newly diagnosed primary Sjögren’s syndrome (SS), presenting with persistent cough, hemoptysis, and dry mucosal symptoms. Chest CT showed thickened airway walls and cystic lung changes, while bronchoscopy revealed nodular lesions with exposed vessels. Congo red staining confirmed amyloid deposition with κ light-chain dominance, consistent with AL amyloidosis. Despite immunosuppressive therapy, airway lesions persisted, highlighting the challenge of managing localized amyloidosis in SS. This case underscores the need for early recognition of TBA in SS patients presenting with respiratory symptoms. |
