Bronchoscopy In Malignant Growths Of The Trachea

The trachea is often secondarily invaded by malignancy of the

esophagus, thyroid gland, peritracheal or peribronchial glands.

Primary malignant neoplasms of the trachea or bronchus have not

infrequently been diagnosticated by bronchoscopy. Peritracheal or

peribronchial malignancy may produce a compressive stenosis covered

with normal mucosa. Endoscopically, the wall is seen to bulge in from

one side causing a crescentic picture, or compression of opposite

walls may cause a scabbard or pear shaped lumen. Endotracheal and

endobronchial malignancy ulcerate early, and are characterized by the

bronchoscopic view of a bleeding mass of fungating tissue bathed in

pus and secretion, usually foul. The diagnosis in these cases rests

upon the exclusion of lues, and is rendered certain by the removal of

a specimen for biopsy. Sarcoma and carcinoma of the thyroid when

perforating the trachea may become pedunculated. In such cases

aberrant non-pathologic thyroid must be excluded by biopsy.

Endothelioma of the trachea or bronchus may also assume a pedunculated

form, but is more often sessile.
