Chest computed tomography scan, bronchoscopy images, and histology of a 72-year-old man with a carinal mass. (A) Chest computed tomography showed a large enhancing mass obstructing the carina.. (B) Bronchoscopy revealed a large hypervascular tumor on the carina obstructing both right and left main bronchi.. (C) Bronchoscopy after removal of the carinal mass using the tip of rigid bronchoscope with pre- and post-application of argon plasma coagulation showed clear bilateral main bronchi.. (D) Her histology showed squamous cell carcinoma.

His chest computed tomography (CT) showed a 3.7-cm enhancing polypoid mass in the lower trachea, several enlarged mediastinal lymph nodes, and a consolidation in the left lower lobe (Fig. 1 A). There was a huge hypervascular mass in his carina, obstructing both right and left main bronchi (Fig. 1 B). After tumor removal, the left and right main bronchi were cleared (Fig. 1 C). His pathologic findings confirmed squamous cell carcinoma (Fig. 1 D); thus, he was transferred to a lung cancer center to receive definitive treatment.

Chest computed tomography scan and bronchoscopy images of a 32-year old woman with a carinal mass.. (A) Chest computed tomography revealed a 1.6 cm enhancing mass on the carina.. (B) Bronchoscopy revealed a narrow stalked tumor on the carina.. (C) Bronchoscopy after removal of the carinal mass using the tip of rigid bronchoscope with pre- and post-application of argon plasma coagulation showed a clear tracheal lumen.. (D) There was no residual tumor or local recurrence on her follow-up bronchoscopy after one month of rigid bronchoscopic tumor removal.

Her chest CT scan revealed a 1.6-cm homogeneously enhancing intraluminal mass without extraluminal extension immediately superior to her carina (Fig. 2 A). A rigid bronchoscopy was performed under general anesthesia, and it revealed a narrow-stalked tumor obstructing her distal trachea (Fig. 2 B). APC was applied before and after the tumor removal for hemostasis and ablation of the residual tumor (Fig. 2 C). FVC of 3.26 L (88% of predicted), FEV1 of 2.81 L (96% of predicted), and FEV1/FVC of 86.2%. Follow-up bronchoscopies at 1 month and 2 years after the tumor removal showed a clear tumor bed and no evidence of tumor recurrence (Fig. 2 D).

Chest computed tomography scan and bronchoscopy images of a 47-year old woman with a carinal mass.. (A and B) Chest computed tomography showed a 1.9cm sized enhancing nodule on the carina. (C) Bronchoscopy revealed a wide based tumor on the carina.. (D) Bronchoscopy after removal of the carinal mass using the tip of rigid bronchoscope with pre- and post-application of argon plasma coagulation showed a widened right main bronchus.

Her chest CT showed a 1.5-cm nodular enhancing mass in her carina (Fig. 3 A). Positron emission tomography-CT was performed to evaluate the malignancy, and it showed a 1.9-cm hypermetabolic lesion in the tracheal bifurcation, suggestive of high probability of lung malignancy (Fig. 3 B). A mass of approximately 2 cm was observed from the carina to the right main bronchus (Fig. 3 C).
