The clinical algorithm for identifying melanoma on patients is represented by the ABCDE rule that was developed by the American Academy of Dermatology, where each letter indicates characteristic changes on the mole we need to identify and monitor.
- A (asymmetry) indicates an asymmetrical, irregular shape
- B (border) indicates uneven, vague and irregular edges
- C (colour) indicates uneven coloration changes and changing of colour
- D (diameter) indicates an increase in diameter or a growth in moles over time
- E (evolution) indicates any change in the size, colour and shape
If there are other occurrences on the mole and other changes such as
- the appearance of wounds
- expansion of the pigment from moles to the surrounding skin
- the occurrence of bleeding
- the appearance of depigmentation and the dwindling of change, they can be a sign of malignant changes to the mole and it is necessary to contact your doctor as soon as possible.
