두피에 발생한 혈관육종의 치험 2례

Abstract

PURPOSE Angiosarcoma of the scalp is unusual vascular tumor originating from endothelial cell. Angiosarcoma is an aggressive tumor with high propensity for both local recurrence and distant metastasis. We report 2 cases of angiosarcoma having poor prognosis recently. METHODS: Case 1 was a 67-year-old male patient. He visited the hospital with a 3x5cm sized discolored mass in forehead. It began at one month ago from coming to the hospital. Case 2 was a 64-year-old male patient. He visited for our hospital to remove a 4x5cm sized scalp mass. He had a pruritis on scalp from 9 months ago before coming to the hospital. Despite of the conservative treatments, the wound was not healed and advanced necrotic lesion with hemorrhage. RESULTS Case 1 was diagnosed as an angiosarcoma. He underwent a radical operation 5 times. But the tumor expanded multiple area in dura & frontal area of the brain. The patient rejected the treatment any more. And he died one month later. Case 2 was diagnosed as an angiosarcoma and metastased to skull in MRI. He got a radical resection including cranium. Three months later, it recurred to ipsilateral Sternocleidomastoideus muscle. He got a additional operation & started radiotherapy. And now he is receiving chemotherapy, but the recurred lesion is expanding. CONCLUSION Angiosarcoma is a highly malignant tumor. Especially it arises in vascularized area, it easily metastases. So it is best to treat angiosarcoma with surgery included wide margins. Despite the small lesion, we remember that angiosarcoma is a tumor that was consider to be metastases.
