Acute abdomen due to rupture of hemangiopericytoma of the greater omentum: case report

Hemangiopericytoma (HP) is a vascular tumor that mostly develops in soft tissues. The greater omentum is a very rare site for its occurrence. We present herein the clinical evaluation and outcome of a very rare case of HP that caused acute abdomen. We evaluated a case of acute abdomen due to rupture of a HP of the greater omentum. The clinical and laboratory findings and treatment modality are reported. A 70-year-old patient with severe abdominal pain was operated with the diagnosis of acute abdomen. A semi-solid mass (12x10x6 cm) originating from the greater omentum was detected during surgery. There was active bleeding from the tumor. Pathologic evaluation of this lesion was reported as benign HP. HP of the greater omentum can be the cause of intraabdominal bleeding leading to acute abdomen. Surgical resection is the treatment of choice, especially in benign hemangiopericytomas.
