Abstract

Extrapleural solitary fibrous tumor-hemangiopericytoma is a rare tumor. We present a case of this tumor arising in omentum, which is an extremely rare site. The diagnosis was confirmed by diffuse expression of STAT6 on immunohistochemistry. The tumor was assigned a low-risk category according to recent risk categorization models. The patient was advised close follow-up as the tumor was excised completely. These tumors have the potential for recurrence and metastasis even after surgical excision. However, there are no definitive guidelines for adjuvant treatment due to lack of data.

Keywords
