ipeh - Intravascular papillary endothelial hyperplasia Wikipedia Core plasmacluster Tip Intravascular papillary endothelial hyperplasia IPEH is a rare benign reactive vascular lesion that grows into an expansile compressing massSpine involvement is rare with only 11 case reports on its occurrence We reported the first case of IPEH in the cervicothoracic spinal canal which was treated via complete resection and had a good prognosis Pathology Outlines Papillary endothelial hyperplasia Intravascular papillary endothelial hyperplasias also known as Masson tumors are rare nonneoplastic vascular proliferation Clinical presentation Patients usually present with an enlarging soft tissue mass 1 Pathology The lesion is a reac Intravascular papillary endothelial hyperplasia IPEH also known as Massons hemangioendotheliome vegetant intravasculaire Massons lesion Massons pseudoangiosarcoma Massons tumor and papillary endothelial hyperplasia is a rare benign tumorIt may mimic an angiosarcoma with lesions that are red or purplish 5mm to 5cm papules and deep nodules on the head neck or upper extremities Noninvasively IPEH has been successfully treated by the betaadrenergic antagonist nebivolol The prognosis of IPEH is excellent Followup of some large series showed no evidence of local invasion or metastasis Nevertheless IPEH may recur if it arises in a primary vascular lesion which may itself recur or if the lesion is incompletely excised Intravascular papillary endothelial hyperplasia IPEH is a benign nonneoplastic intravascular lesion The clinical features of IPEH may mimic other benign lesions including mucocele pyogenic granuloma and hemangioma as well as malignant neoplasms such as angiosarcoma and Kaposis sarcoma 17IPEH is alternately referred to as Massons tumor intravascular angiomatosis and wangunjaya Intravascular papillary endothelial hyperplasia histomorphological and Intravascular papillary endothelial hyperplasia IPEH is a benign tumor of endothelial cells that can affect any blood vessel Learn about its types causes symptoms diagnosis and treatment options 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 headneck region and the extremities The characteristic histomorphological feature of IPEH is a papillary structure covered with hyperplastic endothelial cells within the vascular lumen Intravascular papillary endothelial hyperplasia Intravascular Papillary Endothelial Hyperplasia Massons Tumor Intravascular papillary endothelial hyperplasia histomorphological and Even though IPEH is a nonneoplastic reactive process it can present similarly to other vascular benign or malignant neoplasms The differential diagnosis includes angioma vascular malformation pyogenic granuloma epithelioid hemangioendothelioma angiosarcoma Kaposis sarcoma and other more rare vascular tumors Disease Entity Intravascular papillary endothelial hyperplasia IPEH or Massons tumor Disease Intravascular papillary endothelial hyperplasia also known as Massons tumor is a benign intravascular lesion that can mimic other benign lesions and even some malignancies First described in 1923 by French pathologist Pierre Masson as vegetant intravascular hemangioendothelioma Intravascular papillary endothelial hyperplasia as a rare cause of Intravascular papillary endothelial hyperplasia IPEH Epidemiology Slight female predominance 131 Ear Nose Throat J 2021 Jun 10 Epub ahead of print No known ethnic predilection Average age 31 years range 9 months to 78 years Am J Dermatopathol 19835539 Intravascular Papillary Endothelial Hyperplasia Angiomatosis Intravascular Papillary Endothelial Hyperplasia EyeWiki Intravascular Papillary uludağ Endothelial Hyperplasia Diagnostic Sequence
