Abstract

Abstract Background Tracheobronchial injuries generally occur due to iatrogenic or traumatic causes. Although bronchial rupture due to teratoma and germ cell tumors has been reported in the literature, no cases related to lung cancer have been determined. Our case is presented because of the refusal to be examined for the mass in the lung and the detection of bronchial rupture afterward when he presented with massive hemoptysis. Case presentation A 65-year-old male patient was admitted to the emergency department with the complaint of massive hemoptysis. Six months ago, bronchoscopy was recommended due to the 8 × 7 cm cavitary lesion obliterating the bronchus in the anterior upper lobe of the right lung on chest computed tomography, but the patient refused. The sputum sample, requested 3 times, was negative for acid-resistant bacteria, and no growth was detected in the mycobacterial culture. In the new pulmonary CT angiography, a progressive cavitary lesion invading the right main bronchus, carina, and vena cava superior was observed. Following tranexamic acid treatment and bronchial artery embolization, hemoptysis significantly decreased in the follow-up. In the flexible bronchoscopy performed for diagnostic purposes, the carina was pushed to the left and invaded, and there was damage to the right main bronchus. A biopsy was not performed due to the risk of bleeding, and lavage was performed. Lavage was negative for ARB, there was no growth in the mycobacteria culture, and cytology did not reveal malignant cells. The patient, diagnosed with right main bronchial rupture, was considered inoperable and died 1 month later due to respiratory failure. Conclusions Examinations should be initiated as soon as malignancy is suspected. When diagnosis and treatment are delayed, complications that would be challenging to intervene may develop.
