The lines of Blaschko describe a linear pattern of distribution of various congenital, nevoid, and acquired skin disorders with their suspected embryological origins not yet well understood. These lines were painstakingly and thoroughly documented first by German dermatologist Alfred Blaschko. Blaschko was the son of a physician and was born in 1858 in Freienwalde and died in 1922 in Berlin. He was a private practitioner in Berlin, where his dermatologic interests ranged from dermatitis herpetiformis, leprosy, and, later in his career, occupational skin diseases to social hygiene and venereal diseases.1
