We report here a rare case of epithelioid hemangioendothelioma (EHE) of mandible in an adult male, who presented to our department with a huge mass protruding out of the oral cavity. The patient underwent wide local excision of the mass, and histopathological features favored the diagnosis of EHE, which was finally confirmed by immunohistochemistry with CD31 tumor marker.

Pulmonary Epithelioid Hemangioendothelioma is a rare and low grade tumor of endothelial origin found in the lungs. At onset patients are usually asymptomatic or present with non-specific symptoms. Chest imaging shows the presence of multiple, bilateral small nodules and diagnosis usually requires a lung biopsy. At this time there is no standardized treatment regimen and the prognosis is variable.

Epithelioid hemangioendothelioma (EHE) is a relatively rare and moderately aggressive type of vascular tumor. We describe a case of EHE that presented in a 24-year-old woman as a palpable nodule in the left cervical area. Radiological examinations and fine-needle aspiration cytology led to a preliminary diagnosis of metastatic lymphadenopathy with an unknown primary site. However, during surger...

We report here a case of primary pulmonary epithelioid hemangioendothelioma diagnosed in a 67-year-old Caucasian man, presenting with exertion dyspnoea, dry cough, and multiple bilateral pulmonary nodules revealed by computed tomography. At the 18F-fluorodeoxyglucose positron emission tomography, these nodules were negative. The histopathological diagnosis was made on a pulmonary wedge resectio...

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...

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...

OBJECTIVE To examine treatment of hepatic epithelioid hemangioendothelioma (EHE), a rare vascular tumor with a variable course. Treatment modalities at our institution include liver resection, transplantation, and catheter-based therapies. DESIGN, PATIENTS, AND MAIN OUTCOME MEASURES Retrospective review of 25 patients treated for hepatic EHE (1976-2007). We examined treatment modality, overal...

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare category of vascular tumor with uncertain malignant potential. It commonly presents nonspecific and variable clinical manifestations, ranging from asymptomatic to hepatic failure. In addition, laboratory measurements and imaging features also lack specificity in the diagnosis of HEHE. The aim of the present study is to highlight the dile...
