We report the case of a rare solitary small nodular form of malignant hepatic epithelioid hemangioendothelioma in a patient followed by computed tomography and gadoxetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging with histological analysis. This case showed early peripheral septal and nodular enhancement and delayed centripetal enhancing pattern with capsular retraction, mimicking p...

Epithelioid hemangioendothelioma (EHE) is a rare tumor of intermediate malignancy. We report a case of intracranial and intraorbitar EHE. A 3-year-old girl presented with a 3-month history of progressive left exophthalmia. Neuroradiologic imaging (CT scan and MRI) showed an intraorbitar process with an intense enhancement extending to temporal fossa, ethmoidal bone, nasal fossa, maxillary sinus...

Retiform hemangioendothelioma is a rare intermediate or borderline neoplasm of the blood vessels that mostly occurs in extremities. Here we report a unique case of retiform hemangioendothelioma presented in the external auditory canal. 58-year-old male patient presented with the complaint of right ear swelling for 4 years. On examination, a spherical swelling in the right ear was found occludin...

Hepatic tumours are relatively rare in children, accounting for 1% 4% of all paediatric solid tumors, commonest amongst them are hepatoblastoma, neuroblastoma, and vascular tumors (hemangioendothelioma/haemangiomas). Infantile Hepatic hemangioendothelioma (IHHE) is classically characterised by hepatomegaly, jaundice, congestive cardiac failure with high cardiac output, skin haemangiomas, haemol...

This report describes a patient with metastatic epithelioid hemangioendothelioma treated with bevacizumab and nanoparticle albumin-bound paclitaxel. The treatment was well tolerated and led to the stabilization of an aggressive variant of the disease. This case report is the first one that describes the activity of the combination of chemotherapy and bevacizumab in epithelioid hemangioendotheli...

Multifocal and diffuse infantile hepatic hemangioendotheliomas commonly present with signs of high-output congestive heart failure. In addition, prolonged persistent pulmonary overcirculation eventually leads to the development of pulmonary hypertension at a later age. We report a 2-day old, full-term infant with multifocal, large infantile hepatic hemangioendothelioma, who presented with an ea...

BACKGROUND AND PURPOSE Hemangioendothelioma is the most common parotid gland tumor of childhood, and is diagnosed on clinical grounds, supported by imaging findings. Previous work has suggested that MR is the best imaging technique for assessment of parotid hemangioendothelioma. Demonstration of a reliable sonographic appearance would reduce the need for MR imaging in infants with this lesion. ...

Endothelial cells distinguished by their epithelioid morphology have been recognized for many years. Rosai first characterized them as “histiocytoid” in appearance in 1979 and soon thereafter they became known by the more popularized term "epithelioid". By the early and mid 1980's this nomenclature was incorporated into classification schemes of epithelioid vascular tumors that included reactiv...
