Solitary Fibrous Tumor in Pelvis Extended to Transverse Mesocolon and Peritoneum

Solitary fibrous tumor (SFT) is a rare, spindle-cell neoplasm, which is classified as mesenchymal neoplasm emanating from ubiquitous dendritic interstitial cells. SFTs are benign tumor with a low rate of malignancy developed in intrathoracic areas and its growth is rarely observed in extrapleural locations. Based on to the rarity of malignant SFT, there is no certain treatment to the inoperable malignant. This case study is a report of a man with SFT of the pelvis, transverse mesocolon, and peritoneum. So far, more than 58 patients with SFT of the pelvic have been reported in the literature, out of which 26% of them were malignant either clinically or histologically. The female/male ratio was equal within the age range of 27–83 years. The size of reported tumors were ranged 1–33 cm. Malignancy were reported in 26% of cases.
