Abstract:
Pleomorphic adenoma usually occurs in the salivary glands but rarely in the trachea or bronchi. A 71-year-old man had abnormal shadows on a chest X-ray. Chest CT revealed one tumor in the right basal segment of the lung and another, in the left main bronchus. Bronchoscopic biopsy of the right tumor revealed well-differentiated squamous cell carcinoma. Right lower lobectomy and lymph node dissection were performed (pT2N0M0, stage IB). At the orifice of the left main bronchus, bronchoscopy identified a polypoid lesion nearly obstructing the airway. The lesion was resected with hot snare ablation. The histological examination revealed a mixture of epithelial and myxoid mesenchymal elements, characterized by ductal structures, squamous metaplasia, and cartilage tissue. The diagnosis was bronchial pleomorphic adenoma coexisting with squamous cell carcinoma of the lung.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
