Intravascular Papillary Endothelial Hyperplasia (Masson's Vegetant Haemangio Endothelioma) of the Inner Canthal Area
A case of intravascular papillary endothelial hyperplasia in a 15-year-old male, presenting with a mass in the right inner canthal area of the upper eyelid arising from the right angular vein, is reported.
Intravascular papillary endothelial hyperplasia (Masson's Vegetant Haemangio Endothelioma) is an unusual, benign, vascular lesion characterized histologically by benign proliferation of vascular endothelium. 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 not a specific neoplasm, but is generally believed to be a reactive response that develops secondary to a thrombus in vascular lesions such as varices or hemangiomas. It most often occurs as a painless reddish purple lesion in the the head and neck region or extremities. Intravascular papillary endothelial hyperplasia has been recognized to occur rarely in the ocular area, usually in the eyelid and less often in the orbit.
Results and Conclusion
The main significance of intravascular papillary endothelial hyperplasia is its clinical and histological resemblance to soft-tissue sarcoma.
