Abstract |
Granular cell tumor(formerly named to be granular cell myoblastoma) was first described by Abrikossoff in 1926 and is a rare tumor thought to be of Schwann cell origin. It can occur at any soft tissue of the body, but most cases are found at the tongue, skin, breast and GI tract. Only 6% of them occur in respiratory system. We report two cases of asymptomatic granular cell tumor of the bronchus that were detected incidentally by bronchoscopy. One patient had aspiration pneumonia, the other had immotile cilia syndrome. The former patient was simply observed and bronchoscopic extirpation of the tumor was done in the latter patient. |
