Metastatic malignant solitary fibrous tumour to the infra-temporal fossa.
Malignant solitary fibrous tumours (MSFTs) are rare tumours of fibrous origin, which can occur at all anatomical sites and represent 20% of solitary fibrous tumours. Fine-needle aspiration cytology is not able to distinguish benign from malignant disease, and sufficient tissue has to be obtained for accurate histological diagnosis to be made. Lesions > 10 cm in diameter and incomplete resection or non-resectability are predictive factors for poor long-term survival. We present a 57-year-old patient with a presumably metastatic MSFT from the peritoneal cavity to the skull-base who is in a stable state 17 months after surgical debulking of the skull-base and removal of the peritoneal lesion, followed by post-operative chemotherapy. We suggest the terminology metastatic malignant solitary fibrous tumour for a description of this disease.
