About a submucosal tracheal tumor.

The authors report the case of 46-year-old man with recurrent hemoptysis. Bronchoscopy revealed a submucosal tumor protruding into the tracheal lumen. Transbronchial biopsy failed to obtain a conclusive diagnosis; only surgery allowed complete resection of the tumor and confirmed the diagnosis of tracheal mucoepidermoid carcinoma.

Mediastinal mature teratoma with complex rupture into the lung, bronchus and skin: a case report.

Mature teratoma is the most common primary germ cell tumor in the mediastinum. On rare occasions, cystic teratomas rupture in adjacent structures, such as pleural space, pericardium, lung or tracheobronchial tree. We present a case of a mediastinal mature cystic teratoma in 16-year-old female with complex rupture into the lung, bronchus and skin.
