Endobronchial metastasis (EBM) is uncommon and frequently is seen in renal, breast, and colorectal carcinomas. Other reported primary tumors include melanoma, sarcomas, and tumors of the uterine cervix, testis, ovary, prostate, thyroid, pancreas, and adrenal glands. With reviewing the literature, we were able to find only one report of EBM from fibrosarcoma (in Spanish). We described a 56-year-old woman with EBM of oral fibrosarcoma with local recurrence 13 years after treatment of primary tumor. We conclude that the possibility of central airway metastasis should be kept in mind if patients with a past history of malignancy present with symptoms consistent with bronchial tumors, even if there are 13 years interval. Of several mechanisms EBM, we assume direct aspiration and implantation of tumor cells to bronchus from oral cancer.

Introduction: Endobronchial metastases (EBMs) are rare, with primary tumours predominantly of breast, renal, and colorectal origin. Bronchoscopy is the diagnostic gold standard, with histological confirmation through immunohistochemical study.
Cases: We presented three cases of EBMs, one secondary to colorectal cancer and two associated with renal tumours.

Background Early staging of lung carcinoma (CA) is pivotal in planning the treatment. Lymph node metastasis can be detected by imaging and invasive procedures. The 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) is an emerging noninvasive imaging modality in detecting nodal metastasis.

A man in his 60s, who had undergone surgery for rectal cancer, liver metastases, and lung metastasis, had a past history of myocardial infarction and ventricular fibrillation with reduced cardiac functions. He was referred to our department because of a pulmonary nodule shadow in the S2 right upper lobe and a bronchial cast shadow along the B2 bronchus. Robot-assisted thoracoscopic right S2 segmentectomy was performed and intraoperative bronchoscopy revealed a polyp-like tumor within B2a.

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration is a vital tool for mediastinal and hilar lymph node staging in patients with lung cancer. Despite its high diagnostic performance and safety, it has a limited negative predictive value. Our objective was to evaluate the diagnostic performance of deep learning-based prediction of lung cancer lymph node metastases using convolutional neural networks developed from automatically extracted images of endobronchial ultrasound videos without supervision of the lymph node location.
