  • Angiosarcoma: infiltrating, freely anastomosing channels lined by spindled to epithelioid endothelial cells with marked atypia, surrounding adnexae and dissecting dermal collagen
  • Hemangioma: usually smaller, heavy infiltrate of eosinophils and lymphocytes with germinal centers; usually less atypia
  • Masson tumor: dilated vessel with papillary proliferation of plump endothelial cells without atypia overlying fibrous tissue; fibrin deposition and thrombi present
