Males and females with certain skin conditions and other conditions will also show it under visible light or UV light. These lines create a surface pattern which is distinct from other morphological lines. Lines of Blaschko are usually invisible unless genetic mutations result in mosaicism that alters the pigmentation, proliferation, and/or differentiation of epidermal cells. These lines are.

Blaschko’s lines are unique. The configuration of Blaschko’s lines are varied. Blaschko's lines are the pattern assumed by different naevoid and acquired skin diseases on the human skin . We review the clinical and histologic features of X-linked, congenital/nevoid, and acquired skin diseases that follow. SUMMARY. The lines of Blaschko represent a nonrandom developmental pattern of the skin fundamentally differing from the system of dermatomes. IP is caused by loss-of-function mutations in the IKBKG (inhibitor of kappa light polypeptide gene enhancer in B cells, kinase gamma) gene, formerly known as NEMO (nuclear factor. Typically these lines are not visible; however. The term "pigmentary mosaicism" refers to patterned hypo- or hyperpigmentation resulting from a clone of skin cells with altered ability to produce melanin [ 1 ].

The main purpose of this article is to introduce the concept of Blaschko's lines into the medical, paramedical, and general biological fields of science, and it is hoped that some inter‐reaction can occur between those who regularly see and study other chromosomal and embryological abnormalities. On comparing the overlays of all body and head lesions with the original lines of Blaschko there was an excellent correlation. The peripheral rim can be translucent or slightly pigmented and centre can have dotted vessels or blue/gray dots/granules based on the. Disease with presentation along Blaschko’s lines Dermoscopic features; Porokeratosis: Well-defined peripheral white-coloured rim with two free edges continuous or broken at some parts (“white track”). thought to represent pathways of epidermal cell migration and proliferation during the development of the fetus; become apparent when some diseases of the skin or mucosa manifest themselves according to these patterns. Blaschko’s lines was reported by Richarz et al. The lines of Blaschko represent a pattern followed by many skin disorders. She showed small-sized or aplastic fingernails on the right hand. [] However, some cases of LS showing bizarre pattern of distribution. different dermatoses, but the cause of this Revised version accepted 3 June 1993. Finally, we differentiate Blaschko's lines from other. Blaschko lines - Are humans striped? It looks they are and it is called Blaschko lines. They differ from dermatomes, and appear as single or multiple lines, whorls (swirls) and wave-like shapes in the skin. Linear LP lesions are unilateral and distributed along Blaschko lines [4], [5]. We described herein an 18-month-old male patient with KD who presented with linear, facial erythema coinciding with Blaschko’s lines. 1, 2 The nevi are generally unilateral, following Blaschko lines in linear. 00021-4. Incontinentia pigmenti (IP; Bloch-Sulzberger syndrome, MIM #308300) is an X-linked dominant genodermatosis that is usually lethal in males before birth [ 1-4 ]. They may be either visible at birth or become manifest dur - ing the first years of life. The present CME article will highlight important skin disorders that primarily present in the form of one of the aforementioned patterns.
