PURPOSE:  To review the clinical, radiological, surgical and diagnostic aspects of 19 patients with solitary fibrous tumor of the pleura (SFTP).

METHODS:  The records of 19 patients with pleural tumors seen at the Division of Thoracic Surgery of the Thoracic Diseases Institute - UFRJ, over a period of 13 years diagnosed as SFTP were retrospectively reviewed. Sex, ages, symptoms, locations and methods for diagnosis (imaging and histology) were carefully recorded and reviewed and the results were compared to the international literature.

RESULTS:  Eleven patients were female. The mean age was 58.4 years. 11 patients were symptomatic: chest pain (6), SOBOE and weight loss (5), clubbing (4) and hypoglycemia (2). The chest X-ray was abnormal in all cases. 12 cases were in the right chest. The histological diagnosis was done through biopsy (needle or open) in 2 cases and complete surgical resection in 17. The surgical access was postero-lateral thoracotomy in 14 cases, VATS in 4 and sternotomy in 1. Seven tumors weighted more than 1,100g. The sites of implantation of the lesions were: 11 in the visceral, 1 in costal and 3 in diaphragmatic pleural surface. Three malignant tumors were attached to more than one structure, including pericardium. 18 cases were completely resected (one inoperable). The histology was done by hematoxyllin-eosin stain and vimentin in all cases. The cases with malignant features were submitted to another immuno-histochemical confirmation (CD-34). Fifteen cases were benign and 4 malignant. 3 patients died from relapse and metastases.CONCLUSIONS: 58% of the cases were in male patients. The age peak in our cases was in 6th (7 cases), 5th (4 cases) and 8th (4 cases) decades. Most of our cases were symptomatic. Some cases presented as solitary pulmonary nodules or mediastinal tumors. In 50% of the cases the supposition of SFTP was done.

CLINICAL IMPLICATIONS:  SFTP can mimic every intra-thoracic neoplasm and should be reminded in the differential diagnosis of this kind of lesions.
