Dangerous Moles

Dangerous Moles

Mnemonic A-B-C-D stands for

  • A = stand for Asymmetry of the lesion
  • B= any change of the Border of the lesion
  • C=color of the mole
  • D=diameter of the mole, if it is increasing very fast?
  • E=elevation or evolution change of the mole? If it is changing fast?

Dangerous Moles: Melanoma Spreading With Multiple Satellite Lesions.


Although the mnemonic of A-B-C-D is a useful tool to detect any possibility of malignant change of a particular mole, there is another method of early detection. This is called the detection of “ugly duckling sign”. This is very straight forward, simple yet highly effective in teaching and help detecting the melanoma or any changes of moles. A simple comparison of the person normal mole is made. Any of the lesion that greatly deviate from the normal is a red flag. So long the mole display the “ugly duckling” look will means potential for malignant change. The “little red riding hood sign” means an individual is a very fair-skinned person, and it will be difficult to detect no pigment or very light pigmented mole turning melanoma.

The light skinned individual when having a melanotic melanomas, the border is usually indistinct, making naked eye examination difficult. A dermato-scope may be of great help, which is a special scope to check the non-pigmented melanoma. .

People with a personal or family history of skin cancer or of dysplastic nevus syndrome (multiple atypical moles) should see a doctor at least once a year to be sure they are not developing melanoma.

Surgery is the solution

Removal by full surgical excision procedure is the treatment.
