Answer

Surgical treatment of cutaneous angiosarcoma is as follows [14] :

  • Surgical treatment is contraindicated in tumors extending into vital structures, in those of massive size, or in those with multicentricity.

  • The lesion may be solitary or multicentric and frequently extends laterally throughout the dermis, making gross assessment of surgical margins difficult and necessitating multiple biopsies of the surrounding tissues.

  • In the primary treatment of angiosarcomas of the scalp, recognizing the horizontal and vertical extensions of the tumor is essential, which can only be discerned by microscopic examination of all the margins of the resected specimen. The primary excision of the scalp should be full-thickness, including the pericranium and, if indicated, the outer table of the cranial vault; the margins should be wide (at least 5 cm) on all sides.
