It is clear that the medical community and the public owe substantial gratitude to those who created the ABCD mnemonic for melanoma diagnosis in 1985.1 Undoubtedly, the number of melanomas that have been diagnosed early by the use of this acronym is large.
In a recent editorial titled “ABCDE—an Evolving Concept in the Early Detection of Melanoma,” Rigel et al2 emphasized the earlier recommendation that the inclusion of E for evolving would serve as an additional aid toward the early diagnosis of these lesions.3
