혈관종/혈관기형에서 생긴 혈관육종

초록

Malignant vascular tumor spontaneously arising in a benign hemangioma is exceptionally rare. There are only rare case reports in the literature of angiosarcoma spontaneously arising in a hemangioma/vascular malformation. A new case of angiosarcoma arising in a hemangioma/vascular malformation is described. An 18-year-old female was admitted to our hospital because of a 2-month history of an enlarging palpable mass in left axillary area. Grossly, the tumor was relatively circumscribed, nodular, firm, and soft and measured 6.0x4.5x4.0 cm. The cut surface revealed whitish gray solid area and dark red to tan cystic area containing necrotic material.
