Recurrence of a malignant solitary fibrous tumor of the pleura 17 years after primary tumor resection – A case report

Abstract

Most recurrences of solitary fibrous tumor of the pleura (SFTP) occur within 2 years. Here we report a rare case of bilateral recurrence in a 61 year old female, 17 years after the original surgery for a right sided malignant SFTP. On repeat CT scan a 10 cm right mass and two small left lower lobe nodules were found. Patient underwent staged reoperations. She was also found to have a secondary smaller right tumor intraoperatively. All four tumors were confirmed to be recurrent SFTP on pathologic examination with identical immunohistochemistry to the original tumor.
