The BL were described and drawn by Alfred Blaschko, a German dermatologist, in 1858-1922 [ 1, 2 ]. These lines are to be distinguished from other linear patterns such as Voight's lines, Langer's lines, and the lines of innervation of the spinal nerves. Blaschko’s lines map out a migratory history of ectodermal skin cells after their proliferation and movement from embryonic development into the fully formed organism ; further, skin disorders following these lines may be explained by the mosaicism due to X-chromosome inactivation or early somatic mutations . The most common clinical patterns are streaks and swirls following Blaschko's lines in narrow or broad bands and a block-like distribution. The concept of Blaschko’s lines were first introduced by Alfred Blaschko in 1901. He noticed that about 150 of his patients all had rashes and moles. Exogenous linear patterns are caused by external factors. The most common presenting symptoms of classical LS may include dryness and pruritis ranging to mild to severe.

They do not follow neural, vascular, or lymphatic structures and are distinct from dermatomes as well as Langer′s lines. Last updated October 06, 2023. A diagnosis of scalp mosaicism associated with widespread cutaneous mosaicism due to systematized sebaceous nevus was made. It is also important to mention that not all XX/XY individuals are chimeras. Blaschko’s lines are attributed to the migration lines of epidermal cells during embryogenesis and are characterized by a V-shaped pattern on the posterior midline, S-shape on the abdomen, and spiral on the posterior scalp. Follows lines and swirls called Blaschko lines ; Usually unilateral, but may be bilateral and widespread in severe cases. Lichen striatus is a self-limited lichenoid eruption that follows Blaschko’s lines. Skincondition Characteristics.

Alfred Blaschko in 1901 when he examined over 140 patients with linear skin lesions that followed similar patterns. INTRODUCTION. Thus, the pattern of Blaschko's lines in HI may result from the migration and proliferation of epidermal cells during embryogenesis 17. 6 Dispersed lesions of classical lichen planus can also occur over the Blaschko lines. We also include cutaneous disorders that have a linear distribution but do not follow Blaschko's lines.

Confined mosaicism: Unlike general mosaicism, confined mosaicism occurs when specific body parts or organs are. They are often more visible. Blaschko lines correspond with cell migration or growth pathways that are established during embryogenesis. Background: Nevi are proposed to reflect the mosaicism and thus generally follow the different archetypal patterns of mosaicism.

[] However, some cases of LS showing bizarre pattern of distribution. 2. Blaschko’s lines are embryonal, epidermal cell lines distinct from the dermatome, and cutaneous lesions following Blaschko’s lines are a manifestation of cutaneous mosaicism [5]. The lesions following Blaschko's lines in PCZH may reflect the clonal migration and proliferation of embryonic melanoblasts, resulting in peculiar cutaneous patterns. It presents as a pink rash with raised spotting that comes together to form singular or multiple, dull-red, potentially-scaly linear bands that affect the Blaschko lines.
