Epithelioid hemangioendothelioma (EHE) is a subtype of hemangioendothelioma which is a kind of vascular tumor with the biologic behavior between a hemangioma and a conventional angiosarcoma. Among the 6 subtypes of the hemangioendothelioma, EHE is the most aggressive member of this family and may cause distant metastasis and even death in a minority of cases. We herein present one case of EHE e...

INTRODUCTION Epitheloid hemangioendothelioma is a rare vascular soft tissue tumour of intermediate malignant potential. The tumor affects any age group, and liver is the commonest internal organ affected. Bones as calvarium, spine, tibia and femur may also be affected. The lesion can be multifocal in the liver or the same bone itself and can metastasise to lungs. Here we report a rare case of e...

epitheloid hemangioendothelioma (ehe) is an uncommon angiocentric neoplasm of intermediate malignant potential. this tumor is frequently seen in the lungs and liver, but its presentation in the oral cavity is rare. in the oral cavity, gingival region is the common sites of occurrence. we report a rare case of epitheloid hemangioendothelioma in a 48-year-old male, presenting as a growth in the u...

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...
