A CASE OF PRIMARY ADENOIDCYSTIC CARCINOMA OF TRACHEA

Abstract

A 27-year-old man was admitted to our hospital with the complaint of intense dyspnea. Up to that time, he had been treated. as asthma under a certain physician nearby over half a year. There was an uncertain finding in the simple X-ray, but tomography revealed the existence of a tracheal tumor expanding. Following fiberscopic exam. showed it occupying the inner cavity of trachea. The specimen wasdiagnosed histologically “Adenoidcystic Carcinoma.” And then we anesthetized him using a ventilation bronchoscope inserted through the narrow space in trachea. As the tumor extended over 5 to 6 cm getting close to carina and there was no sign of tracheal cartilage, it seemed to be thought impossible to do circumferential resection of trachea with primary end to end anastomosis. We put a straight silicone tube through the hole made by taking the portion of tumor to keep air way.
Soon after it was changed to silicone T-tube. Continuously irradiation was added with a total dose of 6, 000 rads. Now years after operation, in spite of the tumor remained, he is up and well without any trouble except the inserted T-tube. Adenoidcystic carcinoma is said to be slow in growth and rather benign in behavior, but because of its progressive nature, appropriate surgical procedures in combination with irradiation should be taken in each patient.
