Dermoscopy Clinical Pearls:

  • The presence of leaf-like and spoke wheel-like structures seen with dermoscopy is 100% specific for the diagnosis of basal cell carcinoma.
  • The presence of vessels arranged in a string of pearls pattern seen under dermoscopy is 100% specific for the diagnosis of clear cell acanthoma.
  • The presence of white blotches and strands within the same lesion seen with polarized dermoscopy is highly suggestive of basal cell carcinoma
  • Angulated lines forming a zigzag pattern or forming polygonal shapes is suggestive of pigmented actinic keratosis or lentigo maligna
  • The presence of any of the 10 melanoma specific structures in a melanocytic lesion should prompt consideration for a biopsy
