The tracheal tumor is uncommon, and tracheal inflammatory pseudotumor seems to be rare with only four cases reported in the Japanese literature. We here in report a case of tracheal inflammatory pseudotumor in a 61-year-old Japanese man presenting with dyspnea and wheezing 2 weeks after a sub total gastrectomy Billroth I for gastric cancer in april 1991. At bronchofiberscopic examination a rounded tracheal mass 40 mm distal to the vocal cord was found. High vascular on the surface and obstruction of about 90% of the tracheal lumen was noticed. Surgery was attempted immediately and 25 mm of the trachea was excised. The histopathological findings revealed an inflammatory pseudotumor. We concluded that the tumor was caused by injury during tracheal intubation.
