Intravascular papillary endothelial hyperplasia: report of 4 cases with immunohistochemical findings.
Intravascular papillary endothelial hyperplasia (IPEH) is a benign endothelial proliferation, usually intravascular, that may mimic angiosarcoma. In this report, four new cases of IPEH involving the oral region are described. The affected sites were the lower lip, labial comissure and the submandibular region. After clinical evaluation, the complete removal of the lesions showed a circumscribed...
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 کاملOral Intravascular Papillary Endothelial Hyperplasia Associated with an Organizing Thrombus: Case Report and Immunohistochemical Analysis
Intravascular papillary endothelial hyperplasia (IPEH) is a benign lesion of the skin and mucosa of vascular origin characterized by reactive proliferation of endothelial cells. A 76-year-old woman was referred presenting a painless nodule on the lip. Intraoral examination revealed bluish submucosal nodular proliferation, measuring 10 × 5 × 5 mm, affecting the lower labial mucosa. The lesion ha...
متن کاملIntravascular 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 کاملHIF-1α and VEGF expression correlates with thrombus remodeling in cases of intravascular papillary endothelial hyperplasia.
Intravascular papillary endothelial hyperplasia (IPEH) is histopathologically characterized by endothelium-lined papillary structures encircling an acellular fibrin core. The process of IPEH pathogenesis is unclear. The purpose of our study was to identify histopathological and immunohistochemical characteristics of IPEH to better understand the pathogenesis of this disease. After reviewing mic...
