Extrapleural solitary fibrous tumour (SFT) is a rare mesenchymal neoplasm, with less than 40 cases reported affecting the extremities so far. This tumour 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.
