Abstract:
Deposition of amyloid proteins in extracellular space can occur due to uncontrolled inflammatory processes. Tracheobronchial amyloidosis (TBA) is a rare form of such disease. A 68-year-old woman was evaluated for chronic cough following a COVID-19 infection. Although post-viral sequelae were suspected, further investigation revealed TBA. This condition involves amyloid deposits within the airways. The temporal association with COVID-19 raises a potential etiological link, suggesting viral-induced inflammatory or immune-mediated processes may play a role. This case underlines the need to consider rare etiologies like TBA in patients with unresolved respiratory symptoms post-COVID-19.
