ORBITAL HAEMANGIO-ENDOTHELIOMATA, tumours of angioblastic endothelium, are very rare. Birch-Hirschfeld (1930) and Peters (1931) questioned their occurrence, but they have been described by Adson and Benedict (1934), Rottgen (1950), and other authors. In a series of 222 intra-orbital tumours, Forrest (1949) found one angio-endothelioma, and Iliff (1957) found three cases in a series of 88 primar...

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare neoplasm, largely unresponsive to chemotherapeutic medications, and with varied prognosis. Imaging on computerized tomography may demonstrate perivascular nodules, but diagnosis is ultimately made on biopsy with immunohistochemical analysis. Here we describe a case of PEH in a 14-year-old male with Crohn's disease, which, to our knowled...

BACKGROUND This study aims to analyze the computed tomography (CT) and magnetic resonance imaging(MRI) characteristics of hepatic epithelioid hemangioendothelioma (HEHE). METHODS Eleven patients with histopathologically confirmed HEHE via surgical excision or biopsy were included. Imaging findings of these 11 patients were retrospectively analyzed (CT images obtained from all patients and MR ...

Primary cardiac epithelioid hemangioendothelioma (EHE) is extremely uncommon. To our knowledge, only fourteen cases have been reported. We report a case of a primary EHE of the right atrium which incidentally detected in 77-year-old woman. Echocardiograhpy revealed a 26 × 16 mm right atrial mass attached to the base of the interatrial septum and moderate regurgitation of the tricuspid valve. Th...

Malignant hepatic epithelioid hemangioendothelioma (HEHE) is a rare malignant tumor of vascular origin. Nonspecific symptoms and the absence of experience of surgeons, radiologists, and histopathologists due to the rarity of HEHE make the diagnosis of this entity very challenging. Misdiagnosis is not a rare event, and the consequences of such an event are catastrophic. We report a case of a pat...

Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor which usually occurs in infants. Clinically it appears as ill-defined red to purple indurated plaque. KHE is commonly associated with Kasabach-Merritt syndrome (KMS) and lymphangiomatosis. Microscopically, the tumor is composed of infiltrating lobulated nodules with slitlike or crescentic vessels which are poorly canal...

A clinical case of a Kasabach-Merritt syndrome secondary to kaposiform hemangioendothelioma in 2-month-old child is presented, which was confirmed clinically, laboratory tests and magnetic resonance imaging. The expression the disease characterized by rapidly growing vascular tumor on left thigh that progressed disseminated intravascular coagulation difficult control, requiring multiple transfu...

Epithelioid hemangioendothelioma is a very rare, vascular, low-grade malignant tumor found in the lungs, liver, bone, and other soft tissues. Most patients with pulmonary epithelioid hemangioendothelioma (PEH) are asymptomatic but usually present with multiple bilateral nodular lesions in the lungs. Currently, surgical lung biopsy, histology, and immunohistochemical methods are essential for di...
