Giant solitary fibrous tumors of the pleura: two case reports.

Solitary fibrous tumors of the pleura (SFTP) are rare neoplasms. We report two cases of giant SFTP treated by surgical resection. One of these was enormous (30 x 19 x 18 cm, weight: 4,050 g) and occupied the entire left pleural cavity with complete lung collapse and contralateral mediastinal shift. Both tumors were removed en bloc. The patients had no postoperative complications. Surgical treatment is curative in most patients; resection must be complete because of the possibility of recurrence and metastasis.
