Tracheopathia osteoplastica associated with iron deficiency anemia

Tracheopathia osteoplastica (TPO) is a benign disease of trachea characterised by numerous cartilaginous or bony structures protruding into tracheobronchial lumen. We report a case of a 85-year-old male patient in whom tracheopathia osteoplastica was diagnosed incidentally during bronchoscopy which was missed on chest computed tomography examination. The patient also had iron deficiency anemia, the cause of which was not identified. We review TPO and discuss the associated abnormalities reported in the literature.
