Endobronchial ultrasound-guided transbronchial needle aspiration in intrathoracic lymphadenopathy with extrathoracic malignancy

Figure 1 Endobronchial ultrasound-guided transbronchial needle aspiration for mediastinal lymphadenopathy in patients with history of resected breast cancer. A-D: Female (F)/age: 49 yr, left breast cancer resected 6 yr prior; A: Positron emission tomography-computed tomography (PET-CT) showed subcarinal region lymph node enlarged with maximum standardized uptake (SUV_max) value of 8.1 and right pleura effusion; B: Endobronchial ultrasound (EBUS) scanning for the subcarinal region lymph node; C: Cytology showed adenocarcinoma cells. Hematoxylin and eosin (H&E) staining 40 × 10; D: Histology showed pulmonary adenocarcinoma, H&E staining 40 × 10; E -F: F/age: 45 yr, left breast cancer resected 3 yr prior; E: PET-CT showed right lower paratracheal region lymph node enlarged with SUV_max value of 8.8; F: EBUS scanning for the right lower paratracheal region lymph node; G: Cytology showed adenocarcinoma cells; H: Histology showed breast cancer metastasis, H&E staining 40 × 10).
