Innovative application of intraoperative laser-assisted fluorescence angiography in resection of an angiosarcoma of the scalp

Cutaneous angiosarcoma is a rare, but aggressive malignant vascular neoplasm arising from endothelial cells. Although it only accounts for less than 2% of soft tissue sarcomas and less than 1% of all head and neck malignancies [1], it is often seen in head and neck regions particularly of the scalp and face in individuals over 60years old. Its clinical presentation varies widely and typically deceiving, from bruise-like macule to benign capillary malformation and hemangioma-like lesion. Prognosis is poor due to its high rate of local recurrence and distant metastasis, with reported 5-year survival rate of approximately 10–34% [2].
