Metastatic2
The most common category of nonmesotheliomatous cancer to involve the pleura is represented by extrapleural primary malignancies that secondarily involve the pleura via metastatic spread. (medscape.com)
However, malignant SFTs, which comprise 10%-15% of SFTs, not only aggressively infiltrate adjacent structures but are also capable of metastatic spread. (medscape.com)
