  • E is for Evolving.

How is melanoma diagnosed ABCD?

[1] The “ABCD” method of identification, originally described by Friedman et al., has been a useful tool in facilitating the diagnosis of MM. [2,3,4] This method analyzes four clinical characteristics to identify a malignant melanoma: Asymmetry, Border irregularity, Color variegation, and a Diameter of 6 mm or more.

  • Asymmetry. The shape of one-half of the mole does not match the other.
  • Border. The edges are ragged, notched, uneven, or blurred.
  • Color. Shades of black, brown, and tan may be present. …
  • Diameter. …
  • Evolving.
