Giant cranial extradural primary fibroxanthoma: a case report

Primary fibroxanthoma of the cranium is an extremely rare condition. Xanthomatous tumors of the central nervous system are occasionally associated with diseases such as Hand-Schuler-Christian disease, malignant fibrous histiocytoma, hyperlipidemia, and a complication of metabolic or storage disorders. However, until 2003, only a few cases of primary fibroxanthoma have been reported. We report a giant fibroxanthoma destroying the lateral skull base unaccompanied by a systemic or metabolic disease.
