3 Indeed, some benign naevi can display some or all of the criteria and can change in an innocent way, presenting a challenge to distinguish from a true melanoma

Distinguishing true melanocytic lesions from other pigmented lesions such as benign seborrhoeic keratoses can be difficult. The ABCDE criteria are not very specific.1,2Īlthough it is a very useful global tool which highlights important features found in melanoma, there are important considerations when using the criteria: The ABCD criteria, first introduced in 1985 and expanded to ABCDE in 2004, was introduced to aid non-experts’ diagnosis of pigmented lesions, and over the years has been promoted widely. For elevation you need evolution – change over time – so this will not mean that all raised moles will need referral if they do not change. There is no score and all points in the list are regarded as suspicious – not all of them will be malignant melanomas but these criteria can help in selecting suspicious lesions. The ABCDE criteriaĪ: Asymmetry – is the mole oval/round or is it an odd shape? If divided in half, is the mole a mirror image of itself in both halves?ī: Border irregularity – is the outline smooth or ragged/blurred/notched?Ĭ: Colour change or variability – is the colour of the mole even all the way through?ĭoes the mole contain shades of black/dark brown/grey/blue/white/red in whole or part?ĭ: Diameter greater than 6mm or change in diameter – is the mole larger than the others or atypical in appearance? Has the mole grown?Į: Evolution/Elevation – is the mole changing over time in size, shape or colour? Is it becoming raised? The tool can be used by both clinicians and patients and the simple acronym can quickly and easily be taught to patients for self-monitoring of their moles.

It is helpful to use when considering whether to refer a patient on the urgent skin cancer two week wait pathway, with or without the use of other assessment tools. It can be used to assess a single mole at the time of presentation, as well as for the monitoring of longstanding or multiple moles for changes over time, which may indicate transformation to a melanoma. The presence of any of the ABCDE features should raise suspicion of a melanoma. “Protect yourself from the sun, avoid tanning beds, check your skin monthly, and be aware of changes in your skin, especially in pigmented lesions,” she said.The ABCDE criteria represent a method used to evaluate pigmented (melanocytic) skin lesions in order to aid the detection of malignant melanoma. Tucker stressed that there are proven ways to reduce your risk of skin cancer, and this new tool can help. “But it’s important to be aware that anyone can get skin cancer, regardless of their skin color.”

“The photographs used in the tool show moles and melanomas from trial participants, who are primarily white,” she added. “This tool will help people distinguish normal changes in pigmented lesions from those that should be examined by a health care provider. “Melanomas and lesions suspicious for melanoma vary widely in appearance,” Dr. Dermatologists and other physicians use the ABCDE rule to assess a mole or lesion’s asymmetry, border, color, diameter, and evolving or changing appearance. The tool also describes the different appearances of moles, dysplastic nevi, and melanomas, using the ABCDE rule.

The photos are presented as a series of cases that show changes in individual pigmented lesions over time, including examples of small moles that developed over time into melanomas. These photos form the basis for the Moles to Melanoma tool, explained Margaret Tucker, M.D., the study's principal investigator. Between 20, for example, 98% of patients diagnosed with melanoma that had not spread beyond the initial location on the skin survived 5 years or longer.įor more than four decades, researchers from NCI’s Division of Cancer Epidemiology and Genetics (DCEG) have collected photographs of 29 different pigmented skin lesions from participants enrolled in the NCI Familial Melanoma Study. Melanoma is also the most deadly form of skin cancer, leading many public health organizations to stress the importance of early detection.

Melanoma is among the most common types of cancer in the United States, and the number of new cases has been increasing over the last 40 years. The new tool is intended to help educate the public about the appearance and features of common moles ( nevi), which pose no health risk, as well as those of atypical moles ( dysplastic nevi), which can increase melanoma risk, and actual melanomas. As Melanoma/Skin Cancer Detection and Prevention Month comes to a close and summer begins, NCI has launched a new online tool called Moles to Melanoma: Recognizing the ABCDE Features.
