What is a Masson tumor?

What is a Masson tumor?

Masson tumor (intravascular papillary endothelial hyperplasia) is a rare proliferation of endothelial cells within the wall of a vessel, often thought to represent an aberrant resolution of a thrombosis.

What is papillary endothelial hyperplasia?

Abstract. Intravascular papillary endothelial hyperplasia or Masson’s tumor is a rare reactive disease of vascular origin characterized by exuberant proliferation of endothelial cells notably occurring within blood vessels of head, neck, and extremities.

What is endothelial hyperplasia?

Intravascular papillary endothelial hyperplasia is a reactive proliferative lesion of endothelial cells in blood vessels. It is an unusual lesion constituting about 2% of the benign and malignant vascular tumors of the skin and subcutaneous tissues.

What causes Masson’s tumor?

Intravascular papillary endothelial hyperplasia (IPEH) or Masson’s tumor is a rare benign entity commonly found on the head, neck, and upper extremities. It usually arises within a blood vessel but is considered to be a nonneoplastic reactive process often associated with vascular injury.

What is reactive Angioendotheliomatosis?

Reactive angioendotheliomatosis (RAE) is a rare condition characterized by cutaneous vascular proliferation that usually occurs in patients with diverse types of coexistent systemic disease.

How long can you live with angiosarcoma?

A few research studies show that the survival time for this type of cancers is 15–20 months. In spite of this, 35% of patients survive up to five years.

What is Hemangioendothelioma?

The term hemangioendothelioma describes several types of vascular neosplasms and includes both non-cancerous (benign) and cancerous (malignant) growths. The term has also been applied to those that show “borderline” behavior, intermediate between entirely benign hemangiomas and highly malignant angiosarcomas.
