NIC Esthetician Written ExamScientific ConceptsMedium

A client is concerned about a new, irregular-shaped mole with varying shades of brown and black on their arm. The esthetician, recognizing the importance of early detection, advises the client to consult a dermatologist for further evaluation. Which of the following characteristics is NOT part of the ABCDEs of melanoma detection?

  1. AEvolution (changing size, shape, color)
  2. BBorder irregularity
  3. CAsymmetry
  4. DColor uniformity
Show answer & explanation

Correct answer: D. Color uniformity

The ABCDEs of melanoma detection include Asymmetry, Border irregularity, Color variation (not uniformity), Diameter (larger than 6mm), and Evolution (changes over time). Color uniformity would indicate a benign lesion, not a suspicious one.

Why the other options are wrong

  • A. Evolution, or any change in size, shape, color, or symptoms, is a critical warning sign for melanoma.
  • B. Border irregularity, meaning uneven or notched edges, is a suspicious characteristic.
  • C. Asymmetry is a key indicator of melanoma, where one half of the mole does not match the other.

ABCDEs of Melanoma

A mnemonic used to help detect melanoma, focusing on five key characteristics of moles: Asymmetry, Border irregularity, Color variation, Diameter, and Evolving.

  • Asymmetry: one half doesn't match the other
  • Border: irregular, notched, or blurred edges
  • Color: uneven, multiple shades of brown, black, tan, blue, red
  • Diameter: usually larger than 6mm (pencil eraser)
  • Evolving: changing in size, shape, color, or new symptoms (itching, bleeding)

Memory trick: ABCDE: Asymmetry, Bad Border, Crazy Color, Diameter, Evolving.
