Intravascular papillary endothelial hyperplasia (IPEH, Masson's hemangioma) is a non neoplastic reactive endothelial proliferation most commonly located in the skin or subcutaneous tissues although it has been reported in multiple locations throughout the body. This lesion may arise from malformed or normal vessels primarily, and may develop with hemangioma, pyogenic granuloma, or lymphangioma. This lesion, though benign, is clinically important since it may present as a mass and be confused histologically with angiosarcoma. The authors report a 27 years old patient with a mass in his forearm which results in intravascular papillary endothelial hyperplasia.

Intravascular papillary endothelial hyperplasia (IPEH) known as Masson's hemangioma is a rare benign reactive vascular lesion caused by the abnormal proliferation of endothelial cells. The lesion occurs most commonly in the fingers, head and neck, but very rare in the foot. We report a case of IPEH in the foot treated with operative excision.

Intravascular papillary endothelial hyperplasia (IPEH) has appeared in the literature under a variety of names, including Masson's tumor, Masson's hemangioma, and Masson's pseudoangiosarcoma. It is a benign lesion of the skin and subcutaneous tissue characterized by reactive proliferation of vascular endothelial cells with papillary formations. The clinical picture is not specific and the lesion resembles malignant angiosarcoma clinically and histopathologically. Therefore, it is often mistaken for angiosarcoma and a group of other benign and malignant vascular lesions. We report on a case of IPEH adherent to peripheral nerve treated with operative excision.

Cardiac hemangioma is an extremely rare benign tumor. A 65 years old woman was admitted due to epigastric and chest pain, After we confirmed cardiac tamponade with right atrial mass by chest CT, we performed surgical resection of the mass and identified hemangioma with capillary endothelial hyperplasia on pathologic examination. Therefore, we report the case with literature review.
