title: Acquired persistent atypical lentigines as a failure of 5-methoxypsoralen-containing sunscreens in the photochemoprotection from ultraviolet-radiation-induced damage.
abstract: Acquired persistent atypical lentigines are pigmentary lesions that are unusual both clinically and microscopically. They occur in young adults with photosensitive skin using 5-methoxypsoralen-containing sunscreens during sunbathing. Their biologic behavior is benign, but there are grounds for concern regarding the carcinogenic risk in these patients.
