TRACHEA - Papilloma

The specimen shows an adult trachea; in the lower-third, some 6 cm. above the bifurcation, there is a coarsely papillary nodule, some 2 x 5 cm. in diameter, attached to the antero-lateral wall. The polyp almost completely obstructs the trachea.
This patient showed paroxysmal nocturnal dyspnoea for 16 months prior to admission. Histologically, this appeared to be an inflammatory rather than neoplastic lesion.
