Intravascular papillary endothelial hyperplasia (ipeh), or masson's tumor, is a benign reactive process whereby endothelial cells organize around fragmented thrombi in the presence of venous stasis [1,2,3]. This benign tumor has been well described, affecting blood vessels of the head, neck, and fingers.
Masson’s tumor was first described in an ulcerated he-morrhoidal vein in 1923 by pierre masson and remains a rare disorder. It is a benign, generally intravascular tu-mor which is easily distinguished from an organizing th-rombus. It has been given various names, including mas-son’s tumor, masson’s hemangioma, masson’s intravascular.

Surgery may be an option in some cases, such as when the lesions are caused by a brain tumor. Sometimes, lesions and symptoms don’t improve even after appropriate diagnosis and proper treatment and the goal is to manage symptoms.
Here are a few medical references dealing with the issue of efficacy of octreotide in control of tumor growth and/or reduction. There are more, but these are the initial ones that come to mind plus the 2009 published study. Feel free to print this article and show it to any physician who doubts the efficacy read more.
This lesion is often misinterpreted as soft-tissue tumors and other benign and malignant lesions. We present a case of 13-year-old female with ipeh of scalp causing bony defect because of its rarity and diagnostic challenge, it posed due to nonspecific clinical and radiological findings.
The vasculature structure surrounding the lesion; fnh lesions are usually well defined, with a typical “central scar” on ct scans. Hepatic cysts can usually be differentiated from solid lesions by ultrasound or ct scans. It's helpful to compare the size of the lesion to prior imaging studies (if they exist), to determine if the mass is growing.
This rare breast lesion is caused by organization and recanalization of preexisting thrombus with benign vascular proliferation. During the organization of thrombus, anastomosing vascular channels develop and lesion becomes prominently vascular.
Background: masson's tumor, also known as intravascular papillary endothelial hyperplasia is a rare vascular tumor.
Abstract intravascular papillary endothelial hyperplasia, also known as masson’s tumor, is a rare neoplasm of vascular origin. It hasn’t a characteristic presentation; it is commonly manifested as a subcutaneous tumor simulating benign lesions and malignancies.
When masson's tumor causes bone erosion as a result of pressure effects, its radiologic features can be even more suggestive of malignancy. [15,35] therefore, while radiologic investigations can contribute to management, they are not sufficiently characteristic by themselves to make a diagnosis of ipeh.
Masson first described this lesion in a hemorrhoidal vein in 1923 as a neo-plastic process consisting of papillary hyperplasia of the endothelial cells, with a consequent obliteration of the vascular lumen, followed by degenerative changes.

Brain tumors can develop at any age, but are most common in children between the ages of 3-12, and in adults aged 55-65. Primary brain cancer is the second most common cause of cancer death between birth and the age of 34, and the fourth most common cause of cancer death in men aged 35-54.
Neuroradiologic imaging showed a slow-growing lesion consistent with a low-grade glioma. Intraoperative appearance was of a vascular lesion that was slow filling as demonstrated with indocyanine green video angiography. Histologic analysis following resection revealed intravascular papillary endothelial hyperplasia (masson's tumor).
1 this lesion is also referred to as a masson’s tumor, masson’s pseudoangiosarcoma, and intravascular vegetative hemangioendothelioma. 2 some have suggested that it represents an profuse reparative response to vascular injury. 3 it is important for physicians to perform a comprehensive study on the lesion including clinical and histological.
Masson's tumour is typically positive for cd31, cd34, sma, and factor viii–related antigen. Cd105 is expressed on vascular endothelial cells and is positive in primary vascular neoplasms, differentiating masson's tumour from angiosarcoma. This lesion has an excellent prognosis and are usually cured by simple excision.
