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...

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...

background: early pleural tuberculosis (tb) diagnosis is particularly difficult. the aim of this study was to investigate the diagnostic accuracy of the xpert mtb/rif (xpert) (cepheid, sunnyvale, ca) assay using pleural biopsy and pleural fluid specimens in patients with suspected pleural tb but who had a negative sputum acid-fast bacilli (afb) smear. materials and methods: in this study, 134 s...
