Solitary fibrous tumor (SFT) is a rare tumor affecting adults. The incidence of SFT is 2.8 cases per 100,000, and it is commonly located in the visceral and parietal pleura.1
Extrapleural sites also have been described.2
In contrast to malignant mesothelioma, it occurs independently of asbestos exposure. The diagnosis of SFT requires immunohistologic analysis because of its lack of distinctive histologic characteristics: the "patternless pattern."3
We report an SFT located in the mediastinum that mimicked a neurogenic tumor.
Clinical Summary
A 55-year-old woman was admitted to our hospital with increasing symptoms of dyspnea and cough without sputum production. She denied any history of cigarette smoking and any asbestos exposure. The results of routine blood testing, electrocardiography, spirometry, and arterial blood gas analysis were normal. Chest radiography revealed a well-circumscribed round mass in the left superior mediastinum. A chest computed tomographic (CT) scan confirmed a well-delineated mass of solid appearance in the superior left mediastinum, but the pleural relationship was unclear. This mass measured 6 x 6.5
