Leiomyoma of the trachea--an unusual tumour.

A case of leiomyoma of the thoracic trachea is described in a 35-year-old man. The tumour was excised by sleeve resection and end-to-end anastomosis of the trachea was performed. Leiomyoma is a very rare benign tumour of the trachea. Only 15 cases have been reported in the English literature. Our case was not only confirmed by electron microscopy, but is the first reported case in the respiratory tract to be confirmed by positive immunostaining for desmin.
