Abstract:
A 49-year-old man with severe airway stenosis and SVC syndrome underwent urgent Y-stent placement before diagnosis. Subsequent EUS-B-FNA enabled adenocarcinoma diagnosis. This case highlights that transbronchial biopsy in marked stenosis risks fatal obstruction; thus, transesophageal biopsy should be prioritised to ensure safe diagnosis and genomic testing.
