We report two cases in which TCP\u2010EBUS enabled successful endobronchial ultrasound\u2010guided transbronchial needle aspiration (EBUS\u2010TBNA) of the upper\u2010lobar station 12U lymph node (#12U LN) via B\n                    <jats:sup>3<\/jats:sup>\n                    after conventional bronchoscopic forceps sampling failed to provide a definitive diagnosis. In the first case, forceps biopsy of a left upper lobe tumour was non\u2010diagnostic; TCP\u2010EBUS\u2010guided EBUS\u2010TBNA of the left #12U LN established lung adenocarcinoma with N1 involvement. In the second case, the initial bronchoscopy yielded only cytological evidence of carcinoma without histological confirmation; TCP\u2010EBUS\u2010guided sampling of the right #12U LN revealed metastatic small cell carcinoma. In both cases, the pathological diagnosis of EBUS\u2010TBNA guided subsequent treatment. These cases suggest that BF\u2010UCP190F expands the diagnostic range of bronchoscopy and may serve as a valuable rescue technique for sampling upper lobar hilar lymph nodes in clinical practice.\n
