Endobronchial lesion · bronchoscopy

An endobronchial lesion is an abnormality visible within a bronchial lumen or mucosa.

Locate the lesion anatomically and assess extent; correlate CT before selecting sampling.

Describe mass, thickening, ulceration, vascularity and obstruction; distinguish a lesion from extrinsic compression.

A tumour is possible, but a visible abnormality may also be benign or inflammatory.

Macroscopic appearance does not determine histological type; a peripheral lesion may not be directly visible.

CT and symptoms guide strategy; histology, cytology and further analyses require suitable samples.

Haemoptysis or substantial obstruction warrants assessment of clinical consequences and sampling risk.

Endoscopic appearance does not always distinguish cancer from benign lesions; inadequate sampling may be inconclusive.

Locate and describe the lesion, then obtain confirmation suited to the diagnostic question.
