Abstract

Introduction  Solitary fibrous tumor of the pleura (SFTP) is a rare neoplasm, with ∼1.000 cases reported in the worldwide literature. The initial diagnostic approach is performed by imaging studies. Methods  Retrospectively, we collected four cases of patients with giant SFTP operated in our institution. The sociodemographic, clinical, imaging, macroscopic, and microscopic characteristics of each case are described. Results  All the patients in the series had clinical manifestations, with an average of 23.75 months of evolution. 50% of the tumors were located in the right pleural cavity and 50% in the left. In chest computed tomography (CT), the four cases presented as a solid mass, of heterogeneous density, with greater diameters between 17 and 22 cm, and variable contours (smooth in three cases and lobulated in one patient). Intratumoral calcifications were observed in two cases and pleural effusion in three patients. In surgery, all masses presented pedicles. The histological and immunochemical analysis confirmed the benign nature of three cases and malignancy in one of them. Conclusions  SFTPs are usually benign and have a good prognosis. However, between 10 and 20% of these tumors are malignant. Diagnostic images may suggest the diagnosis of SFTP, but confirmation of the nature of the lesion should be made with the histopathological analysis of the entire surgical specimen.
