Bronchoscopy In Malignant Growths Of The Trachea
Category: BRONCHOSCOPY IN MALIGNANT GROWTHS OF THE TRACHEA
Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery
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.
