Intravascular papillary endothelial hyperplasia of the orbit.
Intravascular papillary endothelial hyperplasia is a rare vascular benign tumour bearing some similarities to malignant angiosarcoma. The case reported here in a 20-year-old girl is of particular interest because the orbital tumour, despite its entirely benign nature, invaded the temporal fossa through the lateral bone of the orbit.
متن کاملConcomitant Retroperitoneal Intramuscular Hemangioma and Intravascular Papillary Endothelial Hyperplasia: An Unusual Case Report
Primary retroperitoneal tumors are rare, and benign retroperitoneal tumors are exceptionally rare. Herein, we present a very rare case of benign concomitant retroperitoneal intramuscular hemangioma and intravascular papillary endothelial hyperplasia, with the unusual presentation of lumbosacral plexopathy. After surgical treatment and rehabilitation, the patient recovered uneventfully. This cas...
متن کاملIntravascular papillary endothelial hyperplasia: histomorphological and immunohistochemical features
BACKGROUND Intravascular papillary endothelial hyperplasia (IPEH) is a benign intravascular process with features mimicking other benign and malignant vascular proliferations. IPEH lesions predominate in the head-neck region and the extremities. The characteristic histomorphological feature of IPEH is a papillary structure covered with hyperplastic endothelial cells within the vascular lumen. I...
متن کاملIntravascular papillary endothelial hyperplasia arising from the upper lip.
We report a rare case of intravascular papillary endothelial hyperplasia (IPEH) arising from the upper lip. Pathologically, it consisted of a few lobulated masses lined by an incomplete fibrous capsule of variable thickness which was separated from the surrounding tissue and which partially formed papillary structures bearing fibrous stalks and a single layer of endothelium. The capillary forma...
متن کاملIntravascular papillary endothelial hyperplasia of the oral cavity.
To examine the pathogenesis of intravascular papillary endothelial hyperplasia (IPEH), a relatively uncommon benign, non-neoplastic vascular lesion, clinicopathological and immunohistochemical studies were performed. Paraffin-embedded tissue specimens of 78 vascular lesions were examined histologically, and 9 cases of IPEH were investigated immunohistochemically using antibodies against CD34, v...
