Carcinoid is one of the most common tumors of the gastrointestinal tract followed by the tracheobronchial tree. Bronchial carcinoid compromises 20% of total carcinoid and accounts for 1–5% of pulmonary malignancies. Carcinoid can be typical or atypical, with atypical carcinoid compromises 10% of the carcinoid tumors. Carcinoid usually presents as peripheral lung lesion or solitary endobronchial abnormality. Rarely it can present as multiple endobronchial lesion. We hereby present a rare case of an elderly gentleman who had undergone resection of right middle and lower lobe of lung for atypical carcinoid. Seven years later he presented with cough. CT scan of chest revealed right hilar mass. Flexible bronchoscopy revealed numerous endobronchial polypoid lesions in the tracheobronchial tree. Recurrent atypical carcinoid was then confirmed on biopsy.

We report an extremely rare case of 79-year-old man, who was discovered with coincidental lung metastasis of prostate cancer and primary lung cancer. The patient presented with low prostatespecific antigen and two lung lesions: one in the right lower lobe, and one in the right upper lobe, 3 years after, he was treated with external beam radiotherapy for Gleason score 4+3=7, cT3aN0M0 prostate cancer. A computed tomography-guided needle biopsy of a nodule in the right lower lobe revealed suspicious metastasis of prostate cancer. Thoracoscopic excisions of both lesions were performed, and each lung lesion was diagnosed as being metastatic prostate cancer and primary lung cancer.

Abstract Background: Bronchoscopy using radial probe endobronchial ultrasound (EBUS) is performed when a peripheral lung lesion (PLL) is suspected to be malignant. However, pulmonary tuberculosis is unexpectedly diagnosed in some patients, and healthcare workers could therefore be exposed to tuberculosis if sufficient precautions are not taken. In this study, we examined the incidence of and factors associated with unexpected diagnosis of pulmonary tuberculosis during bronchoscopy using radial probe EBUS.Methods: This retrospective study included 970 patients who received bronchoscopy using radial probe EBUS between December 2015 and November 2018. Clinical, histological, radiological, and microbiological data were reviewed.Results: Pulmonary tuberculosis was unexpectedly diagnosed in 31 patients (3.2%) during bronchoscopy using radial probe EBUS. Patients with a lower age were significantly more likely to be diagnosed with tuberculosis than elderly patients (odds ratio [OR], 0.951; 95% confidence interval [CI], 0.924–0.978; P = 0.001). Among the various CT findings, a low HUs difference between pre- and post-enhanced CT (OR, 0.976; 95% CI, 0.955–0.996; P = 0.022), the presence of concentric cavitation (OR, 5.211; 95% CI, 1.447–18.759; P = 0.012), and the presence of satellite centrilobular nodules (OR, 22.925; 95% CI, 10.556–49.785; P < 0.001) were independently associated with unexpected diagnosis of tuberculosis.Conclusions: The risk of healthcare workers being exposed to Mycobacterium tuberculosis during bronchoscopy using radial probe EBUS has been underestimated. Our results suggest that healthcare workers in the bronchoscopy suite should consider high-grade respiratory protection when examining patients with risk factors for an unexpected diagnosis of pulmonary tuberculosis.
