Epithelioid hemangioendothelioma is a rare vascular tumor with cytologic behavior between angiosarcoma and hemangioma. We present the case of a 58-year-old male with primary epithelioid hemangioendothelioma of the distal radius measuring 6.2 × 5 cm with extension into the pronator quadratus and brachioradialis muscles. We discuss our approach to performing a limb-sparing resection combined with...

Hemangioendothelioma is a rare vascular tumor characterized by endothelial tumor cells and variable malignant behavior, and it's not common for this lesion to involve the bone. Although there are a few reports of cranial involvement by hemangioendothelioma, only rare cases arising in temporal bone have been published. We present the radiologic findings of a 7-year-old boy who had a high grade h...

INTRODUCTION The pulmonary epithelioid hemangioendothelioma is a rare vascular intermediate malignancy tumour. CASE PRESENTATION A 45-year-old man, he shows an isolated chronic cough with a preserved general state of health. The thoracoabdominal Computed tomography showed three well limited opacities of the right lung, among them one shows some calcifications; which we entirely resected by en...

kaposiform hemangioendothelioma is an aggressive endothelial-derived spindle cell neoplasm that occurs nearly exclusively during childhood and teenage years. the lesion grows rapidly and is often associated with kasabach-merritt syndrome. in this study a 24 days old male neonate who presented with an ill-defined deeply situated violaceous mass on his left arm is described. he had also anemia an...

Epithelioid hemangioendothelioma is a rare vascular tumor with intermediate biologic behavior and metastatic potential. Primary renal epithelioid hemangioendothelioma is extremely rare and we present the second report of this rare tumor in an interesting clinical scenario. A 59-year-old male with established history of widely metastatic high grade esophageal adenocarcinoma was found to have an ...

Retiform hemangioendothelioma was differentiated from low-grade cutaneous angiosarcoma by Calonje et al. [1] in 1994; retiform hemangioendothelioma is a very rare tumor of the blood vessels, with less than 30 cases reported throughout the world [2]. The causes of retiform hemangioendothelioma are unknown [2]. Clinically, this tumor occurs mainly in the limbs of young adults, with greater occurr...

A 30-year-old female presented with multiple, erythematous, velvety, slowly growing, asymptomatic nodules on the scalp of two-year duration. Biopsy revealed a vascular tumor with arborizing blood vessels arranged in a retiform pattern, lined with hobnail endothelial cells that stained positively with CD34, with few intravascular papillae. Two year follow up of the case after surgical excision s...

Pseudomyogenic hemangioendothelioma is an extremely rare soft tissue tumor, also named as epithelioid sarcoma-like hemangioendothelioma, which occurs more frequently in young adult males. It was originally recognized as a variant of epitheloid sarcoma, however it is now concluded as a distinctive, rarely metastasizing endothelial neoplasm. We present a case of pseudomyogenic hemangioendotheliom...

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...

Hemangioendothelioma is a rare neoplasm of bone that uncommonly involves the skull. We present a case of grade III malignant hemangioendothelioma (also known as angiosarcoma) of the skull in a 13-year-old boy and describe the plain film, CT, and MR appearance of this neoplasm as well as its histopathology.
