Primary hemangiopericytoma of the parietal bone: a case report.
UNLABELLED Hemangiopericytomas are rare hypervascular tumors arising from Zimmerman's pericytes. They usually occur in the soft tissue, and intraosseous lesions are very rare. Surgical excision is the first choice for treatment. Many studies show that patients should be monitored for some time following treatment because of a high rate of recurrence and metastasis after radical resection. This ...
متن کاملHemangiopericytoma of the neck
Hemangiopericytoma (HPC) is an exceedingly rare tumor of uncertain malignant potential. Approximately 300 cases of HPC have been reported since Stout and Murray described HPCs as "vascular tumors arising from Zimmerman's pericytes" in 1942. After further characterization, the WHO reclassified HPC as a fibroblastic/myofibroblastic tumor. Long term follow up is mandatory because the histologic cr...

متن کاملA reappraisal of hemangiopericytoma of bone; analysis of cases reclassified as synovial sarcoma and solitary fibrous tumor of bone.
Hemangiopericytoma (HPC) was first described as a neoplasm with distinct morphologic features, presumably composed of pericytes. In soft tissue, it is accepted that most such lesions are solitary fibrous tumors (SFTs), monophasic synovial sarcomas (SSs), or myofibromatoses. It is unclear whether HPC of bone exists. We reviewed 9 primary "HPC" of bone from 4 institutions diagnosed between 1952 a...
متن کاملTreatment Strategy of Intracranial Hemangiopericytoma
BACKGROUND Recent studies suggest aggressive management combining a grossly total resection (GTR) with adjuvant radiotherapy (RT) as a treatment of choice for intracranial hemangiopericytoma (HPC). However, in these papers, the definitions of complete or GTR are equivocal. In the present study, we reviewed the relevant cases from our experience focused on the clinical efficacy of surgical gradi...
