Oral intra vascular papillary endothelial hyperplasia in the floor of the mouth. Indian Journal of Dental Research. 2004 Oct-Dec; 15(4): 149-51http://imsear.searo.who.int/handle/123456789/51837Intravascular papillary endothelial hyperplasia (IPEH) is an unusual vascular lesion of proliferating endothelial cells. It is more frequently seen in the extremities, particularly in the fingers. Oral IPEH has been reported with the common sites being lip, tongue, and buccal mucosa. In this article, we present a case of oral IPEH of the floor of the mouth, an unusual location, presenting in a 9-month-old male. The histogenesis, histologic features, and ultrastructural features are also reviewed. A misdiagnosis of angiosarcoma can be made in a case of IPEH due to similar histopathologic features. It is imperative to rule out this error by an elaborate histopathologic evaluation ofthese lesions.engConnective Tissue --pathologyDiagnosis, DifferentialEndothelium, Vascular --pathologyHemangiosarcoma --diagnosisHumansHyperplasiaInfantMaleMouth Diseases --diagnosisMouth Floor --blood supplyMouth Mucosa --blood supplyMouth Neoplasms --diagnosisMucocele --diagnosisCase Reports
