Southern Medical Journal, 1983
We have described a unique example of intratracheal neurofibroma in a patient with neurofibromatosis. Although tracheal neoplasms are rare, they should be considered in the presence of obstructive respiratory symptoms. Careful scrutiny of plain roentgenograms with special views should be undertaken for optimal evaluation.

AbstractEctopic thyroid tissue within the trachea (intratracheal or endotracheal tissue) is a rare cause of upper airway obstruction. The symptoms may be classical or, as in most cases in which the voice is not affected, the first sign may be a wheeze. This may result in the symptoms being mistaken for asthma.
