Tracheal tumor

Tracheal tumor refers to a tumor that occurs below the cricoid cartilage and above the tracheal carina. It is a rare disease of the respiratory system. It is more common in adults, with about 90% being malignant, mostly low-to-moderate malignancy, and is highly prone to misdiagnosis. Approximately 90% of tracheal tumors in children are benign. The main symptoms of tracheal tumors include irritating cough, sputum production, wheezing, chest tightness after activity, shortness of breath, and blood-tinged sputum.

Pulmonary bulla

Pulmonary bulla, also known as lung bulla, refers to the formation of air-filled cysts larger than 1 cm in diameter within the lung tissue due to increased intra-alveolar pressure, rupture of alveolar walls, and subsequent fusion of ruptured alveoli caused by various factors. Generally, small, solitary pulmonary bullae are asymptomatic. Larger or multiple pulmonary bullae can cause symptoms such as chest tightness, shortness of breath, and dyspnea. Males, tall and thin adults, and long-term smokers are more prone to developing pulmonary bullae.
