Tracheobronchial Amyloidosis in a Patient with Sjgren's Syndrome

A 65-year-old woman was referred to our respiratory department because of incidentally detected endobronchial deposits. She had been diagnosed with Sjogren's syndrome 12 years earlier. Bronchoscopy showed protrusion of the reddened, shiny or edematous mucosa at the orifice of the lower lobe bronchus, suggesting a submucosal tumor. Based on the pathological findings of the transbronchial biopsied specimens, the patient was diagnosed with non-classified type tracheobronchial amyloidosis associated with Sjogren's syndrome, which was negative for both. and. chains, transthyretin and amyloid A. She has remained in good health without a relapse of the tumor.
