Tracheal leiomyoma is a form of a benign tracheal tumor.
On this page:
Epidemiology
They are thought to account for around 1% of all tracheal tumors.
Clinical presentation
Presentation depends on tumor location and size with some reports suggesting patients becoming symptomatic when tumor obstructs more than 75% of the tracheal lumen 2. While they are present and any age, leiomyomas of the respiratory tract are thought to mostly present around a 4th decade 5.
Pathology
Like leiomyomas in general, they are composed of smooth muscle cells. They are often circumscribed firm, whitish-pink tumors. Occasional areas of cystic degeneration may occur (often due to poor vascularization). They can be sessile or widely pedunculated.
Complications
Ulceration and secondary infection may occur 3.
