Intravascular Papillary Endothelial Hyperplasia as an unusual diagnosis for peri-orbital tumour - A case report.

Intravascular papillary endothelial hyperplasia (IPEH) is a rare cause of orbital mass which can affect healthy individuals of any age/sex/race/region. It usually requires a histopathological examination, characterized by the appearance of papillary proliferation of vascular endothelial cells within the lumen of the blood vessel, for the final diagnosis. One should be aware that this is a highly vascular lesion which can cause excessive intraoperative bleeding and incomplete removal can lead to recurrences. IPEH of the orbit/eyelid has been reported in few parts of the world as isolated case reports but none from India so far.
