Solitary fibrous tumor arising in the mons pubis: a case report.

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms of fibroblastic origin that mainly arise from the pleura. Although SFTs arising at numerous extrapleural locations have been reported, extrapleural soft tissue SFTs are extremely rare. The diagnosis of SFTs is based on histologic findings. However, given the histological variability of SFTs, immunohistochemical examination becomes important in their diagnosis. Complete surgical resection is the only and a very important prognostic factor and is recommended for the treatment of both benign and malignant SFTs with a curative intent. Here, the author reports what he believes to be the first case of an SFT originating in the mons pubis.
