Bronchial leiomyoma

A bronchial leiomyoma is a relatively rare form of lung tumours. These tumours can form in the lower respiratory tract tissue of the bronchi, trachea and other lung tissue. They may also be derived from blood vessels.<ref name = saoud2016/> These tumors typically form from the smooth muscle tissue lining the bronchi. They grow as a solitary tumor attaching themselves to the sides of the bronchi.<ref name = card2014/>

Diagnosis

This type of tumor can be mistaken for asthma or chronic pulmonary obstructive disease.<ref name = saoud2016/> The determination of a leiomyoma is done by chest x-rays, blood sample and taking a tissue sample of the tumor. An associated test is for tuberculosis, but the results are negative for this infection.<ref name = card2014/>

Treatment

Surgical removal is the usual treatment to remove the tumor. A less invasive method of removing a small leiomyoma is through a bronchioscopy. Recovery is usually complete.<ref name = card2014/>

Epidemiology

Bronchial leiomyomas are only 0.1% to 2% of benign lung tumours.<ref>http://www.humpath.com/spip.php?article21941</ref><ref name= saoud2016>,
