Although melanoma may have a characteristic appearance, there is no single clinical feature that ensures or excludes a diagnosis of melanoma. Even among expert dermatologists, the clinical diagnosis of melanoma can be made in about 80%–90% of cases. The well-known ABCD acronym for melanoma detection continues to be a useful tool. A: Asymmetry (one half is not identical to the other half) B: Border (irregular, notched, scalloped, ragged, or poorly defined borders)  C: Color (varying shades from one area to another) D: Diameter (> 6 mm) E: Elevation/Evolving Lesions having these characteristics may potentially represent melanoma.
