What does ABCD mean in reference to examination of pigmented areas?

ABCD stands for Asymmetry, Border irregularity, Color variation, and Diameter in reference to the examination of pigmented areas, particularly moles. This mnemonic is a helpful tool for identifying potentially dangerous moles that could be melanoma.

Here's a breakdown:

* A - Asymmetry: One half of the mole doesn't match the other half.

* B - Border irregularity: The edges of the mole are uneven, notched, or blurred.

* C - Color variation: The mole has multiple colors, such as shades of brown, black, red, white, or blue.

* D - Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).

It's important to note that while ABCD is a helpful tool, it's not a definitive diagnostic test. If you notice any suspicious moles, it's crucial to consult a dermatologist for a professional evaluation.
