A very rare blood vessel tumor that usually forms on or under the skin of the arms or legs, but it may also form in deeper tissues, such as muscle and bone. These tumors may spread to nearby tissue, but usually do not spread to other parts of the body. There is often more than one tumor, and the tumor may cause pain in the affected area. Pseudomyogenic hemangioendotheliomas may come back after treatment. They are most common in young adult males. Pseudomyogenic hemangioendotheliomas are a type of vascular tumor.
