Malignant invasive thymoma in the posterior mediastinum.

We present a rare case of malignant invasive thymoma (type A) arising from the posterior mediastinum. A 17-year-old girl was referred to our clinic after detection of a mass on a chest roentgenogram. Thoracoscopy showed a lobulated, pale yellowish mass located in the posterior compartment together with several foci in the lung parenchyma.

Squamous cell carcinoma in a postpneumonectomy cavity.

A 55-year-old woman was referred to our department with the diagnosis of a bronchopleural fistula and empyema. Her medical history revealed that she had undergone a left pneumonectomy 25 years prior due to a destroyed lung associated with tuberculosis. Open drainage and a biopsy was performed because of the large mass detected on thoracic computed tomography.
