To aid patients in identifying possible melanoma, we often recommend the use of either the “ABCDE rule” or the “ugly duckling sign.”
What rule do you use to identify melanoma?

One easy way to remember common characteristics of melanoma is to think alphabetically – the ABCDEs of melanoma. ABCDE stands for asymmetry, border, color, diameter and evolving. These are the characteristics of skin damage that doctors look for when diagnosing and classifying melanomas.
What is the ABCD rule and what is it used for?
Background: the ABCD rule is used to guide physicians, health care professionals and patients to recognize the main characteristics of suspicious skin lesions for melanoma.
What does the ABCD rule stand for in recognizing skin cancer?
The ABCD (Asymmetry, Border, Color, and Dimension) criteria represent a commonly used clinical guide for the diagnosis of early melanoma.
WHAT ARE THE ABCS OF melanoma?
The ABCDEs of melanoma skin cancer are:
- Asymmetry. One half doesn’t match the appearance of the other half.
- Border irregularity. The edges are ragged, notched, or blurred.
- Colour. The colour (pigmentation) is not uniform. …
- Diameter. …
WHAT ARE THE ABCS of moles?
The ABCDEs of melanoma
- A is for Asymmetry. Most melanomas are asymmetrical. …
- B is for Border. Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders.
- C is for Color. …
- D is for Diameter or Dark. …
- E is for Evolving.
How is melanoma diagnosed ABCD?
 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.
What are the ABCD symptoms of melanoma?
The “ABCDE” rule is helpful in remembering the warning signs of melanoma:
- 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. …
What does the B stand for in the ABCD acronym for checking moles?
For melanoma specifically, a simple way to remember the warning signs is to remember the A-B-C-D-Es of melanoma— “A” stands for asymmetrical. Does the mole or spot have an irregular shape with two parts that look very different? “B” stands for border.
How is thickness of melanoma measured?
Breslow thickness is the measurement of the depth of the melanoma from the surface of your skin down through to the deepest point of the tumour. It’s measured in millimetres (mm) with a small ruler, called a micrometer.
What are the 3 types of skin cancer?
Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma.
What is the Abcde rule for observing and recording skin lesions?
The ABCD (asymmetry, border irregularity, color variegation, diameter >6 mm) acronym was created in 1985 to help primary care physicians and laypersons recognize early melanomas that might be confused with benign pigmented lesions.
