Intravascular papillary endothelial hyperplasia is a benign lesion of vascular origin. It is caused by excessive proliferation of endothelial cells in vascular malformations or normal blood vessels. We report the case of a 58-year-old woman sent to our clinic for surgery of an orbital fat prolapse at her right eye. The clinical examination showed a displacable swelling with a slightly livid aspect approximately 2 cm in diameter under the upper orbital rim. After MRI, a biopsy was carried out leading to the histological diagnosis of intravascular papillary endothelial hyperplasia. The complete excision of the remaining tumor was performed 8 weeks later. We discuss this clinical entity and the management of such lesions in the orbital region.

Intravascular Papillary Endothelial hyperplasia (IPEH) are benign vascular lesions rarely described in the pediatric population. We present here the case and the management of a 11-year-old child with a lateral neck mass. The diagnosis of IPEH can be challenging for the clinician and the radiologist as it may mimic other pathologic entities.

Intravascular papillary endothelial hyperplasia, or Masson's tumour, is a benign lesion of the subcutaneous tissue and skin, characterised by a reactive proliferation of endothelial cells within a vessel. Although this pathology can occur at various sites, it is generally rare. Differential diagnosis with other benign lesions or malignancies can be challenging, and since its circumscribed nature is impossible to recognise with a biopsy, excision is frequently required.

Masson's tumor is a benign intravascular lesion of proliferating endothelial cells that accounts for 2% of vascular and subcutaneous lesions. It manifests clinically as a bluish swelling, resembling a mucocele or hemangioma. Intravascular papillary endothelial hyperplasia (IPEH) was coined by Clearkin and Enzinger in 1976 to describe reactive vascular expansion, following traumatic vascular stasis mimicking angiosarcoma.
