Added text to state that between 1998 and 2007, a 2.5% relative yearly incidence increase in pediatric melanoma was observed in Surveillance, Epidemiology, and End Results Program databases; during that time, the average annual incidence in this group was exceptionally low, however, and may have resulted in spurious tends; nevertheless, similar trends have been seen in Sweden. Also add text to state that in the U.S. study of pediatric melanoma, nearly one-half of the patients had local disease, and nearly one-half of the patients had disease with a thickness of less than one millimeter; given that mortality from pediatric melanoma had been fairly stable during those years, it is likely that the increase in incidence can be explained, at least in part, by overdiagnosis (cited Austin et al. as reference 8 and Lewis as reference 9).
