Solitary fibrous tumor of the pleura is a mesenchymal neoplasm that involves the pleura. Because the tumors do not show conventional radiological signs of malignancy and some of them are asymptomatic, a preoperative diagnosis can be difficult and referral for surgery is often delayed. We described a 67-year-old female with a huge pleural solitary fibrous tumor. The tumor was first noted 30 years ago, with a biopsy result that revealed no malignancy. She had been regularly followed up for 10 years, but then was lost. The tumor occupied the whole left pleural cavity with compression of the heart and contralateral lung, and was completely excised through 2 separate thoracotomies. No recurrence was noted after a 1-year follow-up.
