Giant solitary fibrous tumor of the pleura.

Solitary fibrous tumors are rare mesenchymal tumors accounting for <5% of all neoplasms in the pleura and other sites. A 45-year-old man reported to us with cough and dyspnea. Radiological investigations revealed a giant mass displacing the mediastinum to the left. The tumor weighing 3.0 kg was successfully resected via a right thoracotomy. Histology and immunohistochemistry confirmed a benign tumor. Recurrence and malignant transformation of these benign tumors have been reported. Our patient has been followed up for 4 years with no recurrence.
