Solitary fibrous tumor of the abdominal wall.

Solitary fibrous tumors (SFTs) are uncommon neoplasms of mesenchymal origin that usually arise from the pleura. SFTs of the abdominal wall are extremely rare, and only 12 cases have been reported in the English language literature. This report presents a new case of SFT of the abdominal wall in a 74-year-old female.
