A Cancer That Went Up in Smoke: Pulmonary Reaction to e-Cigarettes Imitating Metastatic Cancer.
e-Cigarettes have gained worldwide popularity as a substitute for smoking, but concern has been raised regarding the long-term effects associated with their use. We report a case of a 45-year-old female consumer of e-cigarettes who presented with 4 months of abdominal pain and fever. ⋯ Upon cessation of e-cigarette use (known as vaping), the lung nodules disappeared, and the liver lesions regressed. Our case report suggests that vaping can induce an inflammatory reaction mimicking metastatic cancer.

Technical Aspects of Endobronchial Ultrasound Guided Transbronchial Needle Aspiration: CHEST Guideline and Expert Panel Report.
Endobronchial ultrasound (EBUS) was introduced in the last decade, enabling real-time guidance of transbronchial needle aspiration (TBNA) of mediastinal and hilar structures and parabronchial lung masses. The many publications produced about EBUS-TBNA have led to a better understanding of the performance characteristics of this procedure. The goal of this document was to examine the current literature on the technical aspects of EBUS-TBNA as they relate to patient, technology, and proceduralist factors to provide evidence-based and expert guidance to clinicians. ⋯ Evidence on the technical aspects of EBUS-TBNA varies in strength but is satisfactory in certain areas to guide clinicians on the best conditions to perform EBUS-guided tissue sampling. Additional research is needed to enhance our knowledge regarding the optimal performance of this effective procedure.

Blood supply of the tracheobronchial tree is derived from a dual system involving pulmonary and bronchial circulation. Various primary and secondary abnormalities of central airway vasculature can present with patterns that are distinct during bronchoscopy. ⋯ Thorough knowledge of airway vasculature abnormalities and recognition of possible underlying pathophysiology is vital for the bronchoscopist. This review is a comprehensive description of vascular anatomy of the airway and the different vascular abnormalities that can be encountered during bronchoscopy.
