Retiform hemangioendothelioma (RH) is a rare low-grade variant of angiosarcoma mostly reported on dermis or subcutaneously. A 30-year-old woman suffering from dry cough, dyspnea and pleural effusion has been described. Distinctive symptoms and lesions on high resolution computed tomography (HRCT) scan and common histological, immunological feature are discussed. Diagnosis was made by thoracosco...

A new case of epithelioid hemangioendothelioma is reported to have occurred to a 67-year-old patient who consulted for right-sided chest pain. The work-up showed multiple right pulmonary lesions associated with bilateral moderate pleural effusion and left-sided pleural thickening and three hypodense nodules in the right lobe of the liver, peritoneal thickening, ascites, and multiple vertebral l...

Malignant epithelioid hemangioendothelioma (MEH), also known as high-risk epithelioid hemangioendothelioma, is a low- to intermediate-grade vascular malignancy originally described as a vascular neoplasm of endothelial origin. This very rare vascular neoplasm has been described mainly in soft tissue, but also in various organs and locations, including the liver, lung, brain, colon, lymph nodes,...

Epithelioid hemangioendothelioma is a relatively rare lesion. Although its histogenesis has been well described, its immunohistochemical characteristics remain controversial. A case of epithelioid hemangioendothelioma of the soft tissue of the right leg in a 67-year-old Chinese woman is reported. Histologic findings of intracytoplasmic lumina in the tumor cells and positive immunostaining for v...

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare hepatic vascular tumor that represents a diagnostic challenge. The rarity of this neoplasm precludes establishment of a standard-of-care treatment. Risk factors for HEHE are not well-known. Liver transplant remains the most common therapeutic modality for nonmetastatic disease. This article describes a patient who presented with abdomina...

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare neoplasm of vascular origin. There are three different major imaging patterns identified in thoracic manifestation of epithelioid hemangioendothelioma: (1) multiple pulmonary nodules; (2) multiple pulmonary reticulonodular opacities; and (3) diffuse infiltrative pleural thickening. Radiographically, presence of bilateral multiple nodule...
