It is a very aggressive and fast growing tumor along the peritoneal surfaces of the abdomen and pelvis. It has a typical histologic features and a specific immunohistochemical staining pattern. There is no definite treatment. It responses to surgery and chemotherapy at early period of therapy but relapses soon and rapidly progresses and then causes the death.
