[Hemangiopericytoma of the greater omentum. Videolaparoscopic treatment: case report and review of the literature].

Although hemangiopericytoma (HPT) may arise in any anatomic site, it rarely develops in the greater omentum. To our knowledge, only twelve cases have been reported to date in the English language literature. In this report, we describe the case of a patient with sudden severe lower abdominal pain caused by primary HPT in the greater omentum treated with laparoscopic approach and a review of the reported cases is made.
