“…The development of bronchoscopic procedures with endobronchial ultrasonography using a guide sheath has improved the ability to collect reliable samples (6). To our knowledge, difficulties in making the histological diagnosis of invasive mucinous carcinoma using bronchoscopy have not been emphasized previously.…”

We herein report the case of a 68-year-old man diagnosed with invasive mucinous adenocarcinoma of the lungs. Chest computed tomography showed subpleural ground-glass opacity and small nodules with cavitation. A culture of the bronchoalveolar lavage fluid resulted in the detection of Mycobacterium fortuitum. The patient's lung consolidation rapidly progressed; however, repeated bronchoscopy showed no atypical cells, thus suggesting a diagnosis of organizing pneumonia associated with M. fortuitum infection. However, the surgical biopsy specimen was diagnostic for adenocarcinoma, with no mycobacterial infection. Invasive mucinous adenocarcinoma should not be excluded in the differential diagnosis of patients with clinical features of organizing pneumonia and nontuberculous mycobacterium infection, even if a transbronchial biopsy confirms the absence of malignancy.

Selection of the optimal procedure for minimally invasive diagnosis of peripheral pulmonary lesions (PPLs) may be based on clinical factors; however, selection of diagnostic strategy may also be influenced by cost. Economic analysis of minimally invasive diagnosis of PPL has not been performed previously.Decision-tree analysis was applied to compare downstream costs of endobronchial ultrasoundguided transbronchial lung biopsy (EBUS-TBLB) with computed tomography-guided percutaneous needle biopsy (CT-PNB). Calculations were based on real costs derived from patient data. Sensitivity analyses and probabilistic sensitivity analysis were undertaken to identify the more cost-beneficial approach for varying input parameter values. Cost-effectiveness calculations were based on estimated disutility, according to the wait-trade-off technique.For base-case analysis, initial evaluation with CT-PNB was cost-beneficial (AU$2,724 versus EBUS-TBLB AU$2,748). The variable which exerted the most influence on cost-benefit outcomes was the cost of managing complications. CT-PNB remained the more cost-effective procedure at base-case parameters, although thresholds were identified during sensitivity analysis where EBUS-TBLB became more cost-effective.The costs of EBUS-TBLB and CT-PNB to evaluate PPL appear to be equivalent, but specific clinicalradiologic factors known to influence procedural outcomes will influence cost-benefit outcomes. Further evaluation of patient preferences and their influence on cost-effectiveness are required.

A 71‐year‐old woman was referred to our department due to an abnormal chest shadow. Imaging revealed a pulmonary nodule shadow in the left S6 segment, multiple small nodule shadows in the left pleura, and left pleural effusion. Transbronchial biopsy using endobronchial ultrasonography (EBUS) with a guide sheath was conducted. EBUS showed the probe of the sheath located in the lesion and biopsy was performed in this area. A yellow turbid fluid appeared in the sheath and vacuum aspiration resulted in collection of 200 mL of this fluid. We suspected that drainage occurred because the sheath tip had ruptured the pleural cavity. The pathological diagnosis was adenocarcinoma. It is likely that the EBUS images reflected pleural effusion adjacent to the lesion, and that the complication occurred because the biopsy was performed without awareness of these findings. This complication may be prevented by closer examination of echo findings and rotation of the X‐ray source to ensure performance of the biopsy directly under the pleura.
