Intravascular Papillary Endothelial Hyperplasia (Massons Hemangioma) Presenting as Soft Tissue Mass in Left Scapular Region-An Unusual PresentationMeenu Gill, Ashima Batra, Deepika Jain, Veena Gupta, Rajeev Sen, Sumiti Gupta.
Intravascular papillary endothelial hyperplasia (IPEH) or reactive vascular endothelial lesion is a rare benign condition and is also known as Massons hemangioma. It may appear as a primary or pure form developing in a distended vessel, or it can be associated with hemangiomas, pyogenic granulomas, or lymphagiomas. It is usually confined to the lumen of preexisting vessels or vascular malformations. Nearly all the lesions are intimately associated with a thrombus in various stages of organization. The main significance of IPEH is its clinical and histological resemblance to soft-tissue sarcoma and possible misinterpretation as such. We hereby report a case of IPEH clinically and radiologically misdiagnosed as soft tissue sarcoma, in a 47-year-old man, presenting as a soft tissue mass in the left scapular region.
