Tracheobronchial foreign body aspiration can be a life-threatening emergency, particularly in pediatric subjects. An aspirated solid or a semisolid object may be lodged in the larynx or trachea (1,2). If the object is large adequate to cause almost complete obstruction of the airway, asphyxia can quickly cause death. Lesser degrees of obstruction or passage of an obstructive object beyond the carina may cause fewer signs and symptoms (3). Rigid bronchoscopy is a gold standard procedure for foreign body aspiration diagnosis, management, and treatment. Rigid bronchoscopy has a relatively low complication rate and can be safely applied in experienced hands. Foreign body aspiration accounts for 0.16–0.33% of adult bronchoscopic procedures (2-4). Although many different objects have been reported in the literature which aspirated by the oral way, external penetration and aspiration into the trachea other than the oral route is an extremely rare condition. In this article, we present a case of a drill bit piece penetrating through the anterior neck region to the trachea-bronchial system. Herein we depict a very rare case of aspiration. The patient was admitted to the emergency room with a laceration in the anterior neck region. In his history drill bit piece blew up to the neck region when he was working with the drill machine. He had pain in the neck region with a 1 cm diameter laceration and blood clot (Figure 1.A). Subcutaneous emphysema was detected in the neck region. His blood pressure, heart rate, and oxygen saturation, and blood tests were normal. Posteroanterior chest radiograph and computed tomography indicated with the foreign body was seen in the anterior basal segment bronchus of the right lower lobe and there was also anterior mediastinal and cervical subcutaneous emphysema (Figure 2. A, B, C). We decided to perform rigid bronchoscopy for foreign body removal. In the bronchoscopic examination, there were no obvious pathological findings in the trachea and a drill bit piece was seen in the right anterior basal bronchi that got stuck to the mucosa. There was hemorrhage around the foreign body. After the hemorrhage is aspirated metallic piece was extracted carefully with bronchoscopic optical forceps (Figure 1.B). After the foreign body was removed, hemorrhage was controlled with Ankaferd Blood Stopper (ABS, Ankaferd Health Products Ltd, Turkey) hemostatic agent. No other complications were detected.

Pulmonary nodular lymphoid hyperplasia (PNLH) is a reactive lymphoid proliferation manifesting as multiple solitary nodules or localized infiltrates in the lungs. It is a type of benign lymphoproliferative disease that can affect the lungs. We present the case of a 41-year-old female patient with respiratory symptoms such as productive cough, left chest pain, and dyspnea. Imaging findings revealed two lesions with lobulated contour in the left upper lobe apicoposterior segment and left lower lobe superior segment. After examining the minimally invasive diagnostic methods, this rare PNLH case mimicking malignancy was both diagnosed and treated by surgery. Further studies including more patients and longer follow-ups are needed for this rare disease.
