Solitary Fibrous Tumor of the Pleura: A Rare Cause of Pleural Mass

Patient: Male, 63 Final Diagnosis: Solitary fibrous tumor of the pleura Symptoms: Chronic cough Medication: — Clinical Procedure: CT guided biopsy • surgical resection Specialty: Pulmonology OBJECTIVE: Rare disease BACKGROUND: A solitary fibrous tumor of the pleura is a rare but usually benign mesenchymal tumor arising from the pleura. Patients are often asymptomatic, resulting in the majority of tumors being detected incidentally on chest imaging. We present a case of a large solitary pleural tumor and review the typical radiographic and pathologic findings associated with this finding. CASE REPORT: A 63-year-old white man with chronic obstructive pulmonary disease (COPD) was found to have a large pleural mass on chest radiography during a pre-operative assessment. The tumor was biopsied and findings were consistent with solitary fibrous tumor of the pleura. CONCLUSIONS: SFTPs are generally considered benign tumors although there is a risk of malignant transformation and recurrence. Imaging studies play an important role in identifying the tumor and planes of resection, and histologic diagnosis is critical in differentiating SFTP from other type of pleural masses. Surgical resection is main therapy of choice.
