Five new cases of tracheobronchopathia osteochondroplastica (TBOCP) are reported and clinical, radiological and pathological features are reviewed. TBOCP is a rare disease characterized by cartilaginous and bony nodules lining the mucosa of the trachea and major bronchi. The endoscopic features realize pathological evolution by stadiums. The prognosis is usually favourable. The etiology of TBOCP remains unknown, even though some cases were reported in association with amyloidosis.
