[Giant solitary fibrous tumor of the pleura: A case report and literature review].
Solitary fibrous tumor (SFT) is a derived mesenchymal tumor from spindle cells, mostly occurred in the pleura. To analyze the clinical features of the SFT, data for a patient with SFT that involved in the pleura were retrospectively analyzed by assisted thoracoscope in the Affiliated Hospital of Zunyi Medical College in August 2015. The male patient was 45 years old, who showed the main clinical symptoms of chest pain, cough, sputum, and dyspnea. Large amount of right pleural effusion, chest space-occupying lesions were found by chest CT, suggesting a malignant tumor with metastasis at the 2nd and 3rd right rib. Immunohistochemical results showed: CD34 (+), cytokeratin (-), cytokeratin 5/6 (-), calretinin (-), epithelial membrane antigen(-), mesothelial cell (-), vimentin (++), Wilm's tumor-1 (+), Bcl-2 (+), CD56 (-), CD99 (+), desmin (-), and thyroid transcription factor-1 (-). It was diagnosed as SFT at right side wall layer pleura. SFT is a rare disease and it may occur at any site in the body. It lacks characteristic clinical symptoms and can be asymptomatic, or displays symptoms such as cough, chest pain, dyspnea, and hemoptysis. SFTs can only be conclusively diagnosed based on histopathologic and immunohistochemical characteristics of the tumor, and they are mostly benign. The main treatment for SFTs is the complete surgical resection. The prognosis for this disease is relatively good.
