title: [Solitary fibrous tumor of the meninges].
abstract: We report a case of solitary fibrous tumor (SFT) of the meninges. SFTs have been initially described in the pleura. SFTs show similar histological findings as in other locations. SFTs show a diffuse positive staining for vimentin and CD34. Meningeal SFTs have usually a favourable outcome. These tumors have to be essentially distinguished from hemangiopericytomas and fibrous meningiomas. Immunostaining for CD34 is of value for this purpose. CD34 expression is often patchy and weaker in hemangiopericytomas whereas it is rarely observed in fibrous meningiomas. It is of great interest to isolate SFTs from hemangiopericytomas because of their favourable outcome.
