Extrapleural solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm, with less than 40 cases reported affecting the extremities so far This tumor affects preferentially middle-aged patients (median 50 years) and shows no predilection for sex We report a case with typical clinical, radiologic, histopathologic and immunohistochemical features, discussing the importance of differential diagnosis of other sarcomas. Little is known about the biological behavior of SFT Risk factors for shorter metastasis-free survival include impaired surgical margins, tumor size greater than 10 cm and malignant histology Complete excision is the recommended treatment
