Aggressive neoplasm which is mainly divided into three variants: angiosarcoma of the head and scalp, lymphoedema-associated angiosarcoma and radiation-induced angiosarcoma. It is characterized by a tendency to metastasize to regional lymph nodes and lungs. Prognosis is poor. Clinically, early lesions develop as ill-defined violaceous to bluish areas with an indurated border and advanced lesions become elevated or nodular and occasionally ulcerated. Dermoscopy:[1]

  • Homogeneous patternA pattern lacking any definable pigment structures, structureless pattern with combinations of colors (i.e., whitish, pinkish, reddish, bluish, or violaceous)
  • White lines at the nodular parts.
