Introduction: A meningeal hemangiopericytoma (MHPC) is an aggressive tumor characterized by a high rate of local recurrence and late distant metastasis. The objective of this study was to share our We utilized computed tomography to assure multiple tumor metastasis and cranial recurrence of previous meningeal hemangiopericytoma and clinical laboratory tests and immunohistochemical staining to characterize this case. Magnetic resonance imaging and computed tomography showed the recurrent tumor at original torcular site was increased in size. 2007-06-06 A meningeal hemangiopericytoma (MHPC) is an aggressive tumor characterized by a high rate of local recurrence and late distant metastasis. The objective of this study was to share our experience with the treatment of a MHPC and how to distinguish this tumor from a meningioma. BACKGROUND: Intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC) often shows extracranial metastasis, and treatment options are very limited. Immune-checkpoint molecules have not been studied well in SFT/HPCs, and their role in intracranial SFT/HPCs remains unclear.

Careful long-term follow-up is required because metastases can develop after an extended disease-free interval. Aggressive surgical treatment is recommended for distant metastases. PMID: 19755799 [Indexed for MEDLINE] Publication Types: Case Reports; MeSH terms Thirty-nine chemotherapy trials in 16 patients with metastatic hemangiopericytoma treated at MSKCC and 33 trials from the literature are reviewed.

The histological classification and grading scheme for m-HPC is still evolving and few studies have identified tumor features that are associated with metastasis. Introduction: A meningeal hemangiopericytoma (MHPC) is an aggressive tumor characterized by a high rate of local recurrence and late distant metastasis.

Hemangiopericytoma is an unusual vascular neoplasm that arises from the pericytes of Zimmerman. It is associated with capillaries, therefore they may occur anywhere in the body. Most common locations include the lower extremities, pelvic retroperitoneum, head and neck.

A meningeal hemangiopericytoma (MHPC) is an aggressive tumor characterized by a high rate of local recurrence and late distant metastasis. The objective of this study was to share our experience with the treatment of a MHPC and how to distinguish this tumor from a meningioma. 2013-11-19 · Hemangiopericytoma is a term used to described a group of tumors that are derived from pericytes, the cells normally arranged along specific types of blood vessels called capillaries and venules. These types of tumors are typically slow-growing, may be either benign (non-cancerous) or malignant (cancerous), and may occur anywhere in the body. large series [2, 3], with the ﬁrst metastasis re-corded 5 years after the primary diagnosis in 5–10% of cases [3, 5]. Our patient adds to this experience, with metastatic disease appearing 17 years after the last local recurrence.

We report a case of recurrent hemangiopericytoma of dorsal spine in a 55-year-old women treated with surgery for 3 times, with liver metastasis. Gross total resection, if possible, is the 2003-01-01 2012-09-16 Hemangiopericytoma is a neoplasm that commonly manifests as an intracranial mass lesion.[] According to the 2007 World Health Organization classification, it is a “tumour of the meninges”[] and constitutes approximately 2% of all such tumors.[8 9] Hemangiopericytoma is a clinically malignant tumor due to its high incidence of local recurrence and extraneural metastasis, which eventually Metastasis was defined as the presence of HPC tissue in any extracranial location.

In cases of inoperable recurrence or metastasis, palliative chemotherapy is indicated, though there is currently no approved chemotherapy regimen. Therefore new treatment regimens are needed.

Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the primary meningeal tumor.
