A rare case of diffuse primary tracheo-bronchial amyloidosis presented with respiratory symptoms. Despite bronchoscopic intervention, the patient succumbed to sepsis, highlighting the challenges in managing this condition.

Area of Science:

  • Pulmonology
  • Pathology

Background:

  • Amyloidosis is a rare condition characterized by the buildup of amyloid proteins in organs.
  • Primary tracheobronchial amyloidosis affects the airways, presenting diagnostic and therapeutic challenges.

Observation:

  • A 52-year-old man presented with dyspnea, hemoptysis, and malaise.
  • Initial diagnosis considered cancer, but diffuse primary tracheobronchial amyloidosis was confirmed.
  • Amyloid deposits were not A A type, and adjacent plasma cells were polyclonal.

Findings:

  • Bronchoscopic removal of amyloid masses resulted in severe bleeding.
  • The patient ultimately died from sepsis.

Implications:

  • This case underscores the diagnostic difficulties and aggressive nature of primary tracheobronchial amyloidosis.
