Hemangiopericytoma of the chest wall

Preoperative embolization in surgical treatment of a primary hemangiopericytoma of the rib: a case report

Primary hemangiopericytoma of the rib is extremely rare and only a few cases have been reported. A 62-yr-old man presented with an aching chest pain and dyspnea. Thoracic computed tomography revealed a homogenous mass expanding the right seventh rib. A diagnosis of hemangiopericytoma was established by percutaneous needle biopsy. Preoperative embolization of the feeding vessels of the tumor was performed in order to prevent perioperative bleeding. There was no significant bleeding during the surgery, where complete resection of the tumor with 7th to 9th ribs with a surgical margin of 5 cm was performed. Postoperative course was uneventful and there has been no recurrence for thirteen months. To our knowledge, there has been no report to apply a preoperative embolization of a primary hemangiopericytoma of the rib.

Intrathoracic extrapulmonary tumor mass: hemangiopericytoma

Hemangiopericytoma is an uncommon mesenchymal tumor originating from pericytes. We describe the clinical and morphologic features in a case of intrathoracic extrapulmonary giant hemangiopericytoma. The tumor was radically removed, and the microscopy report was benign hemangiopericytoma. Because of the high risk of local recurrence, long-term follow-up is important in such patients.
