A Rare Case of Leiomyosarcoma Originating from the Abdominal Aorta / 日本心臓血管外科学会雑誌

ABSTRACT

We report an extremely rare case of leiomyosarcoma originating from the abdominal aorta. The patient was a 57-year-old man who had palpable abdominal mass with pain. The symptoms were consistent, and urgent operation was done due to impending rupture of the abdominal aortic aneurysm. The intraoperative findings showed that the mass was a primary tumor of the abdominal aorta, and the histological diagnosis was leiomyosarcoma. It is reported that its prognosis is very poor, but he survived 7.5 years after diagnosis by reason of aggressive management including surgical treatment, chemotherapy and radiotherapy.
