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.

Hemangiopericytomas are soft tissue tumors composed of pericapillary pericytes. These tumors are rare in the lacrimal sac. To the author's knowledge, only four previous cases of these tumors occurring in the lacrimal sac have been reported. A primary hemangiopericytoma of the lacrimal sac in a 34-year-old female is reported. Total excision with the surrounding tissue appears to be the treatment of choice for this tumor.
