pubmed-article:2591619 | pubmed:abstractText | The authors report the case of a 64-year-old female with a pemphigus vulgaris that relapsed on her left cheek following X-irradiation. The lesion developed not only on the irradiated area but also along a linear streak. Blaschko lines seem to represent the linear systematization pattern more likely to account for this unusual distribution. | lld:pubmed |
