두피에 전이된 폐의 혈관육종

Abstract

Angiosarcoma is a rare malignant tumor of an endothelial cell derivation and it accounts for less than 2% of all sarcomas. It is a highly aggressive neoplasm with a poor prognosis and most patients die within a short period after presentation. Although angiosarcoma may occur in any location on the body, it rarely arises from major vessels, but has a decided predilection for the skin and superficial soft tissue. A 39-year-old man was referred to our department with an asymptomatic, firm, ulcerative nodule on his scalp that was noticed almost 2 months previously. He had been diagnosed with lung angiosarcoma 9 month earlier. Histopathologically, the skin specimen showed angiosarcoma. The histological findings of the metastatic skin cancer are usually the same as that of the primary cancer. Metastatic cutaneous angiosarcoma is uncommon. Based on these clinical and histopathological findings, our case seems to be skin metastasis at the scalp from the lung angiosarcoma. (Korean J Dermatol 2011;49(6):520∼523)
