Abstract Background Hemangioendothelioma is a rare vascular tumor of the head and neck region characterized by proliferation endothelial cells with epithelioid morphology. This an indolent known to appear during adult life, potential for recurrence, but unlikely metastasize. Although reports endotheliomas affecting soft tissues, skin, viscera, bone, or lymph nodes have been reported, very few c...

Background: Epithelioid hemangioendothelioma is a rare tumour whose prognosis ranges from benign form similar to hemangioma to aggressive tumors like angiosarcoma. Its localization in the rib is very rare and less than 10 cases of costal localized forms have been reported in the literature. The authors describe another case of costal epithelioid hemangioendothelioma illustrated by microscopic f...

A 19-year-old woman was referred to our hospital because of bilateral multiple nodular shadows on the chest radiograph. She complained of no symptoms. The pulmonary lesions were diagnosed pathologically as epithelioid hemangioendothelioma. She has been followed without treatment for more than 10 years. Among all lesions, only two pulmonary nodules enlarged slightly, and it is interesting that o...

Epithelioid hemangioendothelioma is a rare vascular tumor, which occurs in the lung, liver, bone, and soft tissue. Hypertrophic osteoarthropathy is a syndrome characterized by subperiosteal new bone formation, joint effusion and clubbing, and may be associated with cyanotic heart disease, chronic pulmonary disease, liver disease, and other miscellaneous diseases. The activation of endothelium a...

Background. Hepatic epithelioid hemangioendothelioma is a rare malignant tumor of vascular origin with frequent multifocal appearance. Liver resection may cause tumor spread. Liver transplantation has been indicated for unresectable nodules. We hypothesized that adjuvant interferon treatment is effective to prevent metastasis after liver resection. We report a case of multifocal hepatic epithel...
