hemangioendothelioma/tyrosine

Sunitinib malate (Sutent(TM); Pfizer Inc., New York, N.Y., USA) is a small molecule kinase inhibitor with activity against a number of tyrosine kinase receptors, including vascular endothelial growth factor receptors, stem-cell factor receptor, and platelet-derived growth factor receptors alpha and

A patient with a pleural epitheloid hemangio-endothelioma (EHE) who failed to respond to six cycles of initial chemotherapy with iphosphamide and epirubicine was treated with pazopanib in second-line. A significant subjective and objective metabolic response on (18)F-fluoro-deoxyglucose

BACKGROUND Epithelioid hemangio-endothelioma (EHE) is a rare malignant tumor of vascular origin that electively metastasizes to lungs and liver. METHODS We report the case of a 51-year-old woman with metastatic and progressive EHE of the liver. She was successfully treated with daily administration

Epithelioid hemangioendothelioma (EHE) is a low-grade, malignant vascular tumor that most commonly presents within the liver. Patients with hepatic EHE are often candidates for liver transplantation as the disease is usually multifocal at diagnosis. Although these patients achieve excellent early

Purpose: Pseudomyogenic hemangioendothelioma (PHE) is an extremely rare locally aggressive neoplasm with endothelial differentiation, which often presents with multiple lesions. These tumors have characteristic SERPINE1-FOSB fusions. We report a 17 years old patient with advanced unresectable PHE

BACKGROUND Metastatic epithelioid hemangioendothelioma of the kidney is a rare malignant vascular tumor with a wide spectrum of behaviors. METHODS We present the case of a 53-year-old male patient with tumor metastases which developed after radical nephrectomy. We describe the immunohistochemistry

OBJECTIVE This review highlights the current body of knowledge regarding the role of the vascular endothelial growth factor (VEGF) and its receptor (VEGFR) in angiosarcoma, epithelioid hemangioendothelioma (EHE), and hemangiopericytoma/solitary fibrous tumor (HPC/SFT). Therapeutic agents that target

Recently, a novel monoclonal antibody to vascular endothelial growth factor receptor 3 (VEGFR-3), a tyrosine kinase receptor expressed almost exclusively by lymphatic endothelium in the adult, has been shown to react with a small number of cases of Kaposi's sarcoma (KS) and cutaneous lymphangiomas.

BACKGROUND Pulmonary epithelioid hemangioendothelioma (P-EHE) is a rare tumor, with no established standard treatment. Overexpression of vascular endothelial growth factor receptor 2 (VEGFR-2) has been reported in some P-EHE patients. Apatinib, a new small molecule tyrosine kinase inhibitor that

Hepatic epithelioid hemangioendothelioma is a rare variant of mesenchymal tumor. Surgical resection or partial hepatectomy is the treatment of choice in the case of localized disease. However, in metastatic cases, chemotherapeutic drugs targeting the tyrosine kinase are being used. We hereby present

Vascular endothelial growth factor receptor 2 (VEGFR2) is a primary responder to vascular endothelial growth factor signal and thereby regulates endothelial migration and proliferation. This receptor is expressed in endothelial cells and in some vascular tumors, but many reports also detail its

The mouse is the most commonly used species for in vivo studies on angiogenesis related to tumor development. Yet, to the best of our knowledge, very few reports on the in vitro interaction of the angiogenic basic fibroblast growth factor (bFGF) with mouse endothelial cells are available. Three

BACKGROUND Among the molecules important to angiogenesis and lymphangiogenesis is vascular endothelial growth factor receptor 3 (VEGFR-3), a member of the receptor tyrosine kinases of endothelial cells. This receptor is expressed consistently in normal lymphatics, lymphangiomas, and in Kaposi

C-kit proto-oncogene product (KIT, CD117) is a tyrosine kinase growth factor receptor for stem cell factor. This receptor is important for the development and maintenance of hematopoietic stem cells, mast cells, germ cells, melanocytes, and interstitial cells of Cajal and is constitutively expressed

Vascular anomalies currently are classified according to their clinical and histological characteristics. Recent advances in molecular genetics have enabled the identification of somatic mutations in most types of vascular anomalies. The purpose of this study was to collate information regarding the
