1 Nov 2001 For bone and brain metastases, better tumor control was obtained with palliative Histology proved the metastasis of hemangiopericytoma.

Other drugs which show some activity include vincristine, cyclophosphamide, actinomycin, methotrexate and DTIC. Hemangiopericytoma located in the cerebral cavity is an aggressive tumor of the mesenchyme with oval nuclei with scant cytoplasm. "There is dense intercellular reticulin staining. Tumor cells can be fibroblastic, myxoid, or pericytic. These tumors, in contrast to meningiomas, do not stain with epithelial membrane antigen. The malignant tumor of the Hemangiopericytoma can extend to another bodily region, mainly the lungs and bones.

Hemangiopericytomas of the skull base may be approached directly using the Endoscopic Endonasal Approach Keywords: Glaucoma, Hemangiopericytoma, Metastasis. _____ Introduction Malignant tumors can originate throughout the body, yet despite the well vascularized nature of the uveal tract metastasis to the ocular tissues is not a common occurrence. Lymphoma is the most 2018-08-01 2016-03-01 2011-06-06 Spinal hemangiopericytoma is a rare neoplasm that behaves similar to intracranial hemangiopericytoma, with approximately 140 cases being reported in the literature. 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.

Disease name cavity locations; multifocal and metastatic forms are reported Background: Spinal hemangiopericytoma is very rare tumors with only a few case patients who underwent subtotal resection expired due to tumor metastasis. Late pulmonary metastases from hemangiopericytoma of the mandible: unusual findings on CT and MR imaging.

Metastasis can spread by both lymphatics and blood vessels, with lung and bone being common targets. The frequency of metastases from primary tumors outside the CNS varies from 11.7% (2) to 56.5% (1 1) among series.

Se hela listan på academic.oup.com 2014-09-24 · Hemangiopericytoma is a rare disease entity of soft-tissue sarcoma (STS) that can be cured with surgical resection. In cases of inoperable recurrence or metastasis, palliative chemotherapy is indicated, though there is currently no approved chemotherapy regimen.

Aggressive-behaving sinonasal-type hemangiopericytomas are uncommon and include tumors that are locally destructive or metastatic. 148 Metastasis occurs to the regional lymph nodes and lungs and is usually preceded by recurrent tumor.148 Predicting the biologic behavior of hemangiopericytoma is difficult. 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. Hemangiopericytomas were first described as a unique entity by Stout and Murray in 1942 [ 1 ]. Behavior is variable, and these tumors can metastasize early or late. We recently encountered a hemangiopericytoma metastatic to the lungs 20 years after its initial resection from the mandible.

Skull and abdominal computed tomography (CT), magnetic resonance The authors describe a rare case of hemangiopericytoma with cervical metastasis.

Background: Intracranial hemangiopericytomas (HPC) and solitary fibrous tumors (SFTs) (HPC-SFT) are rare vascular tumors that resemble meningioma on imaging and predominantly affect young adults. HPC-SFT have a high rate of local recurrence with well-known propensity for extracranial metastases. Therefore, the tumor was diagnosed as a metastatic hemangiopericytoma with malignant potential. Careful long-term follow-up is required because metastases can develop after an extended disease-free interval.

She had a voluminous hepatic metastasis and multiple small lung metastases from a meningeal hemangiopericytoma initially operated on 11 years earlier. High blood levels of an abnormal form of insulin‐like growth factor type 2 (IGF II) associated with low blood levels of insulin, growth hormone, IGF I, and IGF BP3 were observed.

Our patient adds to this experience, with metastatic disease appearing 17 years after the last local recurrence.

firstline treatment of advanced or metastatic soft-tissue sarcoma: a metastatic hemangiopericytoma and malignant solitary fibrous tumor.

Severe hypoglycemia is a paraneoplastic complication of some malignancies, mediated most commonly by nonislet cell tumor production of insulin-like growth factor 2 (IGF-2) that activates insulin receptors and increases glucose cell entry. The extent of hemangiopericytoma was classified as localized, regional, or metastatic as per the SEER staging criteria. We also analyzed the outcomes of anticancer interventions, including surgery, radiotherapy, and chemotherapy, for both hemangiopericytoma and hemangioendothelioma. Canine hemangiopericytoma: an evaluation of metastatic potential E. Handharyani, K. Ochiai, T. Kadosawa, T. Kimura, T. Umemura Canine hemangiopericytoma is a common soft tissue neo-plasm in the subcutis of dogs.20 The neoplasm is locally in-ﬁltrative and occasionally recurs although the tumor seldom metastasizes. 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.
