Abstract. A case of hemangiopericytoma of subcutaneous tissue with multiple metastases to the lungs is presented ombined treatment with methotrexate
Blood vessels present in all over the body and hemangiopericytoma tumors are formed anywhere in the body, because of adjacent blood capillaries. Hemangiopericytoma. A hemangiopericytoma is a type of soft-tissue sarcoma that originates in the pericytes in the walls of capillaries. When inside the nervous system, although not strictly a meningioma tumor, it is a meningeal tumor with a special aggressive behavior. It was first characterized in 1942. 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. Hemangiopericytomas are typically slow-growing, may be either benign (non-cancerous) or malignant (cancerous), and may occur originate anywhere in the body where there are capillaries 1) .
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. Clinically, hemangiopericytoma is usually of insidious onset.

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.

2020-03-30 2017-04-10 31 rows Intracranial hemangiopericytoma (HPC) is a rare brain tumor with aggressive biologic behavior associated with high recurrence rate and often with extracranial metastasis. The most common sites of extracranial metastasis of the intracranial HPC are the long bones, lung, liver and abdominal cavity in the order of frequencies. 2018-03-09 2007-05-01 Meningeal hemangiopericytoma (m-HPC) is a rare tumor of the central nervous system (CNS), which is distinguished clinically from meningioma by its tendency to recur and metastasize.

Meningeal hemangiopericytoma (m-HPC) is a rare tumor of the central nervous system (CNS), which is distinguished clinically from meningioma by its tendency to recur and metastasize. The histological classification and grading scheme for m-HPC is still evolving and few studies have identified tumor features that are associated with metastasis.
All four cases were initially diagnosed as atypical meningioma, and all of Semantic Scholar extracted view of "Therapy of hemangiopericytoma with pulmonary metastasis." by W. Bogedain et al. Hemangiopericytoma tumors may occur anywhere in the body on pericyte cells, which are the cells found in capillaries and venules. The brain is a common location for hemangiopericytoma tumors.
