case_images: Bronchoscopic images taken at 34 weeks showed a bronchial tumor of 15 mm in the left main bronchus (a). This lesion was removed after delivery using bronchoscopic surgery (b). Lt: left; Ant: anterior; Rt: right; Post: posterior.

case_images: The tumor obstructed nearly 100% of the trachea (Figure 1(a)). A chest CT taken after delivery revealed a bronchial tumor in the left main bronchus without invasion to surrounding organs (Figure 2), and the patient underwent rigid endoscopic bronchial tumor resection 7 days after the cesarean section (Figure 1(b)).
case_images: Transverse (a) and sagittal view (b) of a chest CT, taken after delivery, revealed a bronchial tumor in the left main bronchus without invasion to surrounding organs (yellow arrowheads).

case_images: A chest CT taken after delivery revealed a bronchial tumor in the left main bronchus without invasion to surrounding organs (Figure 2), and the patient underwent rigid endoscopic bronchial tumor resection 7 days after the cesarean section (Figure 1(b)).
case_images: Macroscopic and microscopic findings of the resected bronchial tumor. The excised specimen occupying the bronchi was soft (a). Pathologically, a nodular polypoid tumor is arising from the bronchial wall, based mainly at the membranous portion consisting of a mixture of epithelial and fibromyxoid stromal elements. In addition, neither a high mitotic activity nor extrabronchial invasive growth is noted, indicating the diagnosis of a low-grade mucoepidermoid carcinoma (b, c).
