Abstract
We describe 4 florid examples of tracheopathia osteoplastica (TPO) discovered incidentally at autopsy. the sparsity of previously reported cases of TPO from Australia possibly reflects a lack of awareness of this entity rather than its true incidence. the more recent literature concerning the etio-pathogenesis, pathology and clinical complications of this uncommon condition is reviewed. in our view TPO is a distinct entity and does not represent a late stage of diffuse tracheal amyloidosis.
