Epithelioid hemangioendothelioma in adults

Background: Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor which has an intermediate aggressive behavior. Although the value of liver transplantation (LT) is well established, its place in the management of HEHE is still unclear Epithelioid hemangioendothelioma (EHE) is an ultra-rare, translocated, vascular sarcoma. EHE clinical behavior is variable, ranging from that of a low-grade malignancy to that of a high-grade sarcoma and it is marked by a high propensity for systemic involvement. No active systemic agents are curren Epithelioid hemangioendothelioma (EHE) of soft tissue is a distinctive vascular tumor that has been variously considered a tumor of borderline malignancy and low-grade angiosarcoma. The majority of cases are associated with low mortality, but some metastasize and cause patient death Epithelioid hemangioendothelioma in the right auricle of an adult, male Rhesus macaque (Macaca mulatta).

Lung disease is most commonly characterized by multiple nodules Epithelioid hemangioendothelioma (EHE) is a rare malignant vascular neoplasm that arises from vascular pre-endothelial or endothelial cells [].It can occur anywhere in the body, such as the liver, lung, skin, bone, spleen, pleura, and lymph nodes [2,3,4].The first case of EHE was reported by Weiss and Enzinger in 1982 [].In the 2013 World Health Organization classification of sarcomas, EHE is. WWTR1-CAMTA1 rearranged epithelioid hemangioendothelioma (see comment) Comment: Tumor is composed of cords and small nests of large endothelial cells with abundant eosinophilic cytoplasm embedded in a myxohyaline stroma. Immunohistochemically, the tumor cells are positive for ERG, CD31, CAMTA1, focally positive for keratin and are negative for.

Hepatic epithelioid hemangioendothelioma is an extremely rare malignant vascular tumor which is often multifocal and, in many cases, discovered incidentally. Here, we describe the clinicopathological features of hepatic epithelioid hemangioendothelioma cases seen in our practice and present a detailed review of the published literature. All cases of hepatic epithelioid hemangioendothelioma. Epithelioid Hemangioendothelioma (EHE) is a rare cancer that belongs to the group of cancers called sarcomas. EHE is a vascular sarcoma. This means it originates in the cells that line the inside of blood vessels. 'Epithelioid' refers to the elongated shape of the cells when seen under the microscope Epithelioid hemangioendothelioma occurs in the calvarium, spine, femur, tibia and feet of adults during the second or third decade. Multiple lesion may be present, either in the same bone (particularly in the tibia or fibula), in adjacent bones in the same limb, or in widely separated bones

Epithelioid hemangioendothelioma, an ultra-rare cancer: a

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor which has an aggressiveness graded between hemangioma and hepatic hemangiosarcoma (HHS). 1 The disease has been documented in infants (0-3 years), children and adolescents (4-18 years), and adults (>18 years) Kaposiform hemangioendothelioma, or KHE, is a type of tumor that grows in the blood vessels. Blood vessels help move blood around the body. This tumor usually grows just underneath the skin, but it can also grow deeper inside the chest or abdomen Some of the rare vascular tumors that affect children, teens, and young adults are: Angiosarcoma. Epithelioid hemangioendothelioma. Kaposiform hemangioendothelioma. Enlarge. Vascular cancers can form from the cells of the circulatory system, which is made up of blood vessels (left). They can also form from the cells that make up the lymphatic.

Conventional epithelioid hemangioendotheliomas (EHE) have a distinctive morphologic appearance and are characterized by a recurrent t(1;3) translocation, resulting in a WWTR1-CAMTA1 fusion gene. We have recently encountered a fusion-negative subset characterized by a somewhat different morphology, i What are the symptoms of epithelioid hemangioendothelioma? EHE typically appears in young adults, though the tumor may be diagnosed in younger or older adults. The symptoms of EHE depend on the tumor's location and can differ from patient to patient Epithelioid hemangioendothelioma, or EHE, is a rare vascular tumor of young adults (though can occur in young children) that starts in the cells lining the blood vessels of soft-tissue, bone and body organs- commonly the liver, lungs and bone. They vary in how they grow. In many children the tumor is non-cancerous (benign) and grows very slowly. Epithelioid hemangioendothelioma is a unique tumor of adult life which is characterized by an epithelioid or histiocytoid endothelial cell. Forty‐one cases of this rare tumor have been recognized at the Armed Forces Institute of Pathology. They may occur in either superficial or deep soft tissue, and in 26 cases appeared to arise. Epithelioid hemangioendothelioma (EHE) is a rare malignant hepatic neoplasm of vascular origin that develops in adults. It is more common in women than in men. No risk factors or specific causes have been identified [102]. Macroscopically, two different types of EHE have been described [27]

This rare tumor is commonly found incidentally and not too often is mistaken radiologically and histologically for another tumor. No single treatment strategy has yet been established for it, partly due to its variable clinical course, ranging from an indolent tumor with prolonged.

The classic form (distal-type) of epithelioid sarcoma mainly occurs in teenagers and young adults. A rarer form, called large-cell (proximal-type) epithelioid sarcoma, tends to be more aggressive and mainly affects adults. Epithelioid sarcoma tends to have a high rate of recurrence and can spread to other areas The histological diagnosis was epithelioid hemangioendothelioma. The patient was neurologically intact and tumor-free 18 months after surgery. To our knowledge, this is the fifth patient reported with intracranial epithelioid hemangioendothelioma and the first adult patient for whom complete data are available Epithelioid hemangioendothelioma (EHE) is an uncommon vascular neoplasm. Its intracranial occurrence is rare, and the literature review revealed only 23 cases (14 adults and 9 children).

Epithelioid hemangioendothelioma (EHE) is an extremely rare sarcoma with a highly variable spectrum of disease. It may have a benign, indolent course or an aggressive one. It is difficult to predict outcomes for these tumors. 36 The tumor originates from vascular endothelial cells within medium to large vessels. Epithelioid hemangioendothelioma (EHE) is a vascular tumor of bone and soft tissues with clinical and histologic features that can range between those of hemangioma and angiosarcoma. EHE arises from both vascular endothelial and pre-endothelial cells; therefore, the clinical behavior of EHE tumors can be quite diverse. Before its characterization by Weiss and Enzinger, EHE was initially.
