Abstract
- Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's pseudoangiosarcoma, is an unusual pattern of organization of a thrombus within a vein, or within one or more of the component vessels of various vascular abnormalities, such as cavernous hemangioma, pyogenic granuloma and lymphangioma. It is characterized by the development of endothelial-lined papillary projections in a vascular lumen. Lesions of IPEH usually occur on the head, neck or upper extremities as a solitary reddish or bluish nodule. Herein we report a 34-year-old female who presented with multiple bluish nodules on the left hand, which upon histopathological examination showed intravascular papillary endothelial hyperplasia.
