We present the case of a solitary fibrous tumour (SFT) in the anterior mediastinum (Fig. 1), with a preoperative diagnosis of thymoma. SFT is a rare neoplasm originating from CD-34-positive dendritic mesenchymal dendritic cells. Although its usual site is the pleura, it should be included in the differential diagnosis of mediastinal tumours. Extrapleural SFT show a more aggressive behaviour than pleural SFT: infiltration of margins, pleomorphism, hypercellularity, high mitotic index and necrosis. Although our case was a hypercellular lesion without atypia or necrosis, <4 mitoses/2 mm² and free surgical margins, the literature recommends close follow-up.
