Round solid or cystic mass in the lung

Teratoma of lung refers to those who have no teratoma in the mediastinum and originate in the lung. It is a rare benign tumor of the lung. There have been several reports in China in recent years. Intrapulmonary teratomas may be vagal embryonic tissues, descending along the bronchi, and forming tumors that surround the lung embryo base. Intrapulmonary teratomas are located in the lung parenchyma or in the bronchial lumen, and are mostly round parenchymal or cystic masses of varying sizes. The patients were mostly over 30 years old, with similar numbers of males and females. No symptoms such as hemoptysis, fatigue, weight loss, and chest pain. Often seen for secondary infections. May have club-like fingers. X-ray examination is mostly the surface of secondary lesions, such as lung abscess, bronchiectasis, atelectasis and so on.
