Abstract

BCC is dermoscopically typified by its characteristic vascular pattern (arborizing vessels), the presence of pigmented structures, and ulceration. White shiny strands and blotches are an additional criterion seen only with polarized light (Figs. 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6).
  • Vascular pattern: arborizing vessels (thick vessels with multiple branches) and superficial fine telangiectasia

  • Pigmented structures: there are two main subcategories, depending on the depth of pigment
    • Brown-colored structures:
      • Maple leaflike areas

      • Spoke-wheel areas

      • Concentric structures

    • Blue-gray-colored structures:
      • Multiple blue-gray dots or small globules

      • Blue-gray ovoid nests

  • Ulcerations: single or multiple and in different sizes and colors

  • White shiny blotches and lines
