case_images: As the tumor was in the greater omentum and dilated veins up to 7-8 mm were going to the splenic hilum, the greater omentum was mobilized from the transverse intestine and radical omentectomy was performed (Figure 2).
case_images: Solitary fibrous tumor and the omentum removed.

case_images: Histologically the peritoneal tumor consisted of fibrous and fibromyxoid tissue with vessels of various sizes and uneven cellularity, irregular fibrous squamous cells with monomorphic oval/oblong nuclei, and a small number of typical mitoses (up to 3 mitoses per 10 high-powered fields (HPFs)) (Figure 3). Immunohistochemical analysis revealed that the tumor was positive for STAT6 and CD34 (Figure 3 and Figure 4).
case_images: The tumor consists of spindled to ovoid cells arranged in fascicles in collagenized stroma with branching , dilated and hyalinized blood vessels.
