Although the pleura is the most common site of origin, SFTs arise in many other body organs and locations. Sixty to 80% of intrathoracic SFTs arise in the visceral pleura. The second most common location within the thorax is the parietal pleura. There is no predilection for laterality. Occasional tumors may arise in the mediastinum, from the diaphragm, or within the lung parenchyma. [3] In a large series of extrathoracic SFTs, 11% were found to have atypical (malignant) features.
