Core Tip

Core Tip: Solitary fibrous tumor (SFT) is a rare fibroblastic mesenchymal neoplasm that affects spindle cell soft tissues, demonstrating broad-spectrum biological behavior; it is ordinarily benign, and rarely known to metastasize. SFT occurs primarily in the serosa tissue structure in the pleura and the thorax, and can be found throughout the body, though extra-thoracic localization, including the cephalic region, is uncommon. We have reported the first known case of intracranial malignant SFT metastasized to the chest wall; this case suggests the need for careful, detailed examination, and careful follow-up when encountering patients presenting with a mass.
