In 1901, the German dermatologist Alfred Blaschko described a system of cutaneous lines that represented the typical pattern that linear nevi appeared to follow. These were first demonstrated by German dermatologist Alfred Blaschko in 1901. TLDR. LPP along Blaschko's lines has been associated with susceptibility to genetic mosaicisms. Typically these lines are not visible; however. Linear LP lesions are unilateral and distributed along Blaschko lines [4], [5]. The Stripes on Humans: An Exploration. How do you say Blaschko lines?

Fig 1 Acne predominantly on the left upper portion of the back at age 15 years. Method: One hundred eighty-six figures showing skin lesions following Blaschko's lines on the head and neck were collected from literature. They differ from dermatomes, and appear as single or multiple lines, whorls (swirls) and wave-like shapes in the skin. Ophthalmologic evaluation revealed right microphthalmia, aniridia and sclerocornea. A case of male patient with adult blaschkitis presenting as unilateral asymptomatic erythematous edematous papules, papulovesicles, and plaques over Blaschko's lines, in which skin biopsy revealed coexistent pathological features of lichen striatus and adult blaschkitis along with blood eosinophilia, has been presented here.

Four other patterns of mosaicism are also discussed: blocklike, phylloid, large. The lines are distinguished from other morphological lines of the skin and do not represent vascular, lymphatic or nervous structures. Lichen planus (LP) is an inflammatory dermatosis that presents with pruritic papules, with LP lesions along the lines of Blaschko representing a rare variant. Disorders with a neuronal origin follow this pattern of distribution. Blaschko’s lines become visible, if the mutation causes, or makes the skin it effects, more susceptible to diseases that alter the pigment of the skin. Dossi Cataldo et al. To recap, since 2012 or earlier, waves of social media users searched for “humans have stripes,” “humans have invisible stripes,” or “Blaschko’s lines,” likely landing on Wikipedia’s. This contribution reviews the clinicopathologic spectrum of skin lesions that follow Blaschko lines. [] It is usually unilateral and single, although bilateral or multiple LS have been previously reported in the literature. These stripes, which are known as Blaschko’s lines, were discovered by dermatologist Alfred Blaschko in 1901. Possibly genetic factors or environmental triggers have a role to play in its development. Case Presentation. Clinical findings such as adherence to Blaschko's lines, associated morphological findings (including other cutaneous lesions), and systemic manifestations can be used to further characterize and diagnose variants of the disorder. According to this result, the linear hypomelanotic lesions along Blaschko's lines in HI may develop as a consequence of mosaicism of epidermal cells. 62% of all patients. Blaschko’s lines, also called the Lines of Blaschko, named after Alfred Blaschko, are lines of normal cell development in the skin. 3A 27-year-old Japanese woman presented with small atrophic hyperpigmented macules on her extremities since early childhood. 线状苔藓是获得性、炎症性皮肤病，呈自限性，皮损线状排列，无其他症状，主要发生于儿童，一般单侧发疹，最常累及四肢，沿Blaschko线连续性或间断性分布。起病突然，数周内全面进展，通常在6-12个月内消退。本专题将讨论线状苔藓的发病机制、临床表现、诊断和治疗。Cutaneous conditions can follow Blaschko's lines on the skin, which are thought to reflect patterns of cell migration and clonal expansion during embryonic development of the epidermis. Together with new insights on the role for lysosomal signalling in embryonic stem cell differentiation, mutations in the X-linked transcription factor 3 ( TFE3. The lines of Blaschko represent a pattern followed by many skin disorders. The main differential diagnoses are the other linear dermatoses that run along Blaschko's lines, especially an inflammatory linear verrucous epidermal naevus (ILVEN), however, when compared to lichen striatus, ILVEN have the following characteristics: 75% of lesions arise during the first five years of life, most often in the first six months Blaschko lines are distinctive whorled and linear patterns on the skin first described by the dermatologist Alfred Blaschko in 1901. In our case, the cytogenetic analysis on peripheral blood. (C) Blaschko linear, erythematous and pigmented atrophic line with a verrucous part (6-months-old).

It appears in females two or three times as often as in males. The stripes are sort of U-shaped down our fronts and V-shaped on our backs, wavy on the head and face and we have basic simple stripes on our extremities. Over 100 years later, scientists agree the most likely explanation is that Blaschko lines trace the paths formed during embryonic development, as skin cells migrated and proliferated. Physical examination showed interfollicular erythema and follicular plugging without skin atrophy or sclerotic change. [] It is usually unilateral and single, although bilateral or multiple LS have been previously reported in the literature. The patient was diagnosed with SV along Blaschko's lines (Fig. The conductor of Blaschko represent ampere pattern assumed by multiple different nevoid and acquired skin diseases on the human.

The system of Blaschko's lines on the head and neck as elaborated by this study is more precise than previously published diagrams and shows definite crossing of lines. When six-months-old, there were Blaschko linear,. We also include cutaneous disorders that have a linear distribution but do not follow Blaschko's lines. Blaschko's lines were first described by Alfred Blaschko in 1901 and are thought to reflect patterns of cell migration and clonal expansion during the embryonic development of the epidermis [2. Different descriptive terms for these disorders include "linear and whorled nevoid hypermelanosis" (LWNH), [1] "progressive cribriform and zosteriform. have reported the case of a 48-year-old patient with three clinical subtypes [ 12 ], while Vineet et al. The lines of Blaschko are a pattern of lines on the skin that represent the developmental growth pattern during epidermal cell migration. These diseases are hypothesized to be caused by genetic mosaicism resulting from processes such as lyonization or somatic postzygotic mutation. Blaschko’s lines are an invisible pattern on the skin that represents the developmental pathways of cells. Blaschko's lines are the pattern assumed by many different naevoid and acquired skin diseases on the human skin and mucosae. Close. Four other patterns of mosaicism are also discussed: blocklike, phylloid, large. Neither a specific disease nor a predictable symptom of a disease, Blaschko's lines are an invisible pattern built into human DNA [citation. Blaschko’s lines, also called the Lines of Blaschko, named after Alfred Blaschko, are lines of normal cell development in the skin. Pigmentary mosaicism refers to patterned hypo- and/or hyperpigmentation that results from genetic heterogeneity of skin cells. These lines are. Although they are most recognized in people with.

This concept was first introduced by the German dermatologist Alfred Blaschko at the 7 th Congress of German Dermatological Society in 1901. 2 They are usually seen on either the scalp, face, trunk, and/or limbs. Blaschko’s lines are actually traces of the migration and proliferation of skin cells during embryonic development. Certain unusual variants of LP may present a difficulty in diagnosis. 5-1 cm hypopigmented or white macules that merge to form larger patches; Macules cover more than two dermatomes and are often on both sides of the body; Patches are not symmetricalFor example, Blaschko's lines were present in a girl with a karyotype mos 47,XX,+7/45,X (Niessen et al. These diseases are hypothesized to be caused by genetic mosaicism resulting from processes such as lyonization or somatic postzygotic mutation. Physical examinationConfluent and reticulated papillomatosis (CARP), also called confluent and reticulated papillomatosis of Gougerot and Carteaud, is an uncommon skin condition that consists of multiple small, hyperkeratotic macules or papules that coalesce to form patches or plaques with a reticulated (net-like) pattern peripherally. The present author previously proposed that in addition to the line of migration, proliferation pattern of the embryonic cells at some later stage might have. A major differential diagnosis is inflammatory linear verrucous epidermal nevus (ILVEN). These distinct types of archetypical arrangement should not. Lichen planus; Blaschko’ lines; Lichen planus involving nails; Case report: Core Tip: Lichen planus (LP) with lesion distribution along the Blaschko’s lines can be differentiated from other skin lesions with linear distribution by dermoscopy and pathological biopsy. [] These lines create a surface pattern which is distinct from other. This contribution reviews the clinicopathologic spectrum of skin lesions that follow Blaschko lines. Blaschko线是以首次描述这些线的人名字命名的。. In 55 (85%) children the skin lesions were confined to one side of the body, showing no preference for either left or right side. On the chest and upper back they rise in a swirl before. General mosaicism: Occurs when there are two or more cell lines existing in a baby. The most common clinical patterns are streaks and swirls following Blaschko's lines in narrow or broad bands and a block-like distribution. We review the clinical and histologic features of X-linked, congenital/nevoid, and acquired skin diseases that follow. BACKGROUND The system of Blaschko's lines has been insufficiently documented on the head and neck. Skincondition Characteristics. The.

On the face, Blaschko lines typically run perpendicularly on the forehead, along the lateral aspects of the nose, and down to the chin. In the present instance, the linear erythema resolved promptly in response to primary IVIG therapy as with the other KD symptoms, suggestingThese preliminary results support the ideas that (1) Blaschko's lines represent single clones of epidermal cells; (2) in patients with HI and severe neurological involvement mosaicism, if detectable, is best shown in keratinocytes; and (3) the cytogenetic defect in epidermal cells may be directly responsible for the failure of pigmentation in HI. A Case of Segmental Vitiligo Along Blaschko's Lines. A diagram of the distribution pattern of these lines has since been drawn and is now referred to as the lines of Blaschko. Incontinentia pigmenti (IP; Bloch-Sulzberger syndrome, MIM #308300) is an X-linked dominant genodermatosis that is usually lethal in males before birth [ 1-4 ]. However, these lines are invisible in most people. 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. 1 He originally described these lines as “a system of lines on the human skin that linear nevi and dermatoses follow”. It depends on their location. Alfred Blaschko is credited with the first demonstration of these lines in 1901. Some acne-like horny plugs in the center of the papules merge into plaques. The most frequent variant of LPP is linear, as was observed in the current case, with zosteriform or Blaschkoid LPP being much less common. The most common clinical patterns are streaks and swirls following Blaschko's lines in narrow or broad bands and a block-like distribution. Blaschko Lines in Broad Bands. Pigmentary mosaicism refers to patterned hypo- and/or hyperpigmentation that results from genetic heterogeneity of skin cells. Introduction: Pigmentary mosaicism (PM) manifests by pigmentation anomalies along Blaschko's lines and represents a clue toward the molecular diagnosis of syndromic intellectual disability (ID). Blaschko lines track distinct patterns (Figure 3). After Happle’s viewpoint 2 in Chuong et al. Unilateral distribution of lesions in arm, leg. Lichen striatus is clinically diagnosed on the basis of its appearance and characteristic developmental pattern following the. They never cross the previous truncal middle line But run for it. The stripes run up and down your arms and legs and hug your torso. Confined mosaicism: Unlike general mosaicism, confined mosaicism occurs when specific body parts or organs are. Citation 59 On the other hand, blaschkoid LP is differentiated from linear LP, as it adheres to Blaschko’s lines. Lichen planus may affect the skin (cutaneous lichen planus), oral cavity (oral lichen planus), genitalia (penile or vulvar lichen planus), scalp (lichen planopilaris), nails, or esophagus. A postzygotic mutational event may lead. A 32-year-old Taiwanese man presented to our clinic with a 6-month history of linear hair loss in a wavy and curved pattern across the parietal and occipital scalp, resembling the distribution of Blaschko's lines. Conclusions: Our data indicate that linear morphoea follows the lines of Blaschko. Thomas et al.

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 [13]; further, skin disorders. Out of the 3 reported cases of linear LSA that appeared on the face, one case showed facial lesion following the Blaschko's line without any oral mucosal lesion, and the other 2 cases showed additional oral mucosal. R. 2Atrophic, squamous, and erythemato-violaceous plaques following Blaschko’s lines were noted on her left knee .

A minimal number of patients may have generalized skin lesions. They become apparent when some diseases of the skin or mucosa manifest themselves according to these patterns. comedone-like pits coronoid lamellaIn an infant or young child, a nevus sebaceous (sebaceous naevus) presents as a solitary, smooth, yellow-orange hairless patch or plaque, often oval or linear in shape. In McCune-Albright syndrome, the segmental hyperpigmentation runs in such broad bands that it is often difficult to appreciate the link to Blaschko’s lines. The genetic mosaicism in an acquired Blaschko-linear inflammatory dermatosis could be accountable for the cutaneous antigenic mosaicism that can prompt a mosaic T-cell response based on the trigger of. 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 lines of Blaschko represent a pattern followed by many skin disorders. Blaschko's lines are invisible on the majority of humans, including under UV. They can be macular or with some elevated component that may develop. They follow a dorsal “V” shape over the spine and back, an “S” shape over the lateral and anterior areas of the trunk, an arc from the chest to the shoulders, a spiral shape on the scalp, and a linear longitudinal pattern on the extremities. Method: One hundred eighty-six figures showing skin lesions following Blaschko's lines on the head and neck were collected from literature. Background: Nevi are proposed to reflect the mosaicism and thus generally follow the different archetypal patterns of mosaicism. Blaschko's lines are the pattern assumed by many different naevoid and acquired skin diseases on the human skin and mucosae. it's like trying to make a Neapolitan ice cream but with three things of vanilla instead of each flavor. Skin findings of KD are polymorphous, varying from diffuse maculopapular eruptions to psoriasiform lesions. Blaschko lines correspond to the path of embryonic cells as they grow outward from the dorsal midline toward the ventral. (A) Blaschko lines distributed lesions (2-weeks-old). Recognition that a cutaneous lesion follows Blaschko lines may represent an important clue for the diagnosis. 1 Because many skin disorders that followed these lines were present at birth, Blaschko suspected that they had an embryonic origin. Lichen striatus is an acquired, asymptomatic, and self-limited linear inflammatory skin disorder that predominantly affects children [ 1,2 ]. Kawasaki disease (KD) is a self-limited, systemic vasculitis developing in early childhood. Thus, the pattern of Blaschko's lines in HI may result from the migration and proliferation of epidermal cells during embryogenesis 17. These lines are consistently S-shaped on the abdomen, V-shaped on the upper spine, perpendicular along the length of the arms and legs, inverted U-shaped on the chest, and follows a more. We described herein an 18-month-old male patient with KD who presented with linear, facial erythema coinciding with Blaschko’s lines. These lines are to be distinguished from other linear patterns, such as Voight's lines, Langer'sBlaschko’s lines, also called the lines of Blaschko, named after German dermatologist Alfred Blaschko, are lines of normal cell development in the skin. LWNH refers to the swirls and whorls of hyperpigmentation distributed along Blaschko’s lines. 5 It has been postulated that the cells along Blaschko lines contain distinct genotypes that may ultimately permit a unique response to stimuli such as. They curve around the sides, like tiger stripes. It is solitary in 50% of cases and may follow Blaschko lines. Method: One hundred eighty-six figures showing skin lesions following Blaschko's lines on the head and neck were collected from literature and patient files,. The lines of Blaschko represent a classic pattern of cutaneous mosaicism that can be observed in a wide variety of congenital and acquired skin disorders. Blaschko’s Lines.

Cutaneous conditions can follow Blaschko's lines on the skin, which are thought to reflect patterns of cell migration and clonal expansion during embryonic development of the epidermis. Blaschko's lines are the most common pattern of mosaicism. Its constancy in Table 1 Linear dermatoses explained on the basis ofmosaicism. Thus, the pattern of Blaschko's lines in HI may result from the migration and proliferation of epidermal cells during embryogenesis 17. Paul Blaschko, who first described them in the early 1900s. Cutaneous mosaicisms usually manifest by specific patterns on the skin and the archetypic pattern is the system of Blaschko lines, but others include checkerboard, phylloid, large patches without midline separation and lateralization. If occurring on the trunk or extremities, they follow Blaschko lines. The eruption is typically unilateral, most often involving the extremities, and follows the lines of Blaschko in a continuous or interrupted pattern. The eruption affects the lines of Blaschko, which are thought to be embryonic in origin. 1 Mendelian diseases may present in this manner at birth but complex traits may also manifest like this later in life. Background: The system of Blaschko's lines has been insufficiently documented on the head and neck. Mosaic individuals are composed of two. Blaschko’s lines are named after Alfred Blaschko, a German dermatologist who first described them in 1901. They were described and drawn by Blaschko 75 years ago. Blaschko lines presenting as narrow bands are common in mosaic disorders (e. Linear and whorled nevoid hypermelanosis was first described as a distinctive entity in 1988 by Kalter [ 1 ], and to date, approximately 40 patients. Lines of Blaschko are usually invisible unless genetic mutations result in mosaicism that alters the pigmentation, proliferation, and/or differentiation of epidermal cells. This is also a rare case in which 90% repigmentation was achieved in patient with segmental and nonsegmental vitiligo following Blaschko. Seventeen cases of childhood discoid lupus erythematosus (DLE) have been previously reported in the literature. TIL Human skin is overlaid with Blaschko’s Lines, a pattern of stripes covering the body from head to toe, invisible unless under UV light or if certain skin conditions manifest them mentalfloss. These lines were painstakingly and thoroughly documented first by German dermatologist Alfred Blaschko. Finally, we differentiate Blaschko's lines from other patterns on the skin such as. We also include cutaneous disorders that have a linear distribution but do not follow Blaschko's lines. Blaschko's lines were delineated in 1901 by a German dermatologist Alfred Blaschko . Four other patterns of mosaicism are also discussed: blocklike, phylloid, large patches. 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. Vitiligo is a common acquired depigmenting disorder of the skin and mucosa, affecting 0. Lichen striatus (LS) is an uncommon linear dermatosis that most commonly affects children aged 4 months to 15 years and is distributed along the lines of Blaschko. Noun [edit] Blaschko's lines pl (plural only) Lines of normal cell development in. Cutaneous mosaicism does not always follow Blaschko lines, which may relate to the time the mosaicism arises during embryonic development. The term "pigmentary mosaicism" refers to patterned hypo- or hyperpigmentation resulting from a clone of skin cells with altered ability to produce melanin [ 1 ]. These lines are unique and rarely found in nature and are a result of abnormal cell migration during development in the womb. 5%~1% of the population worldwide 1. They remind us of our individuality – that even within our own bodies, no two cells are exactly alike. How to say blaschko's lines in English?

We present this case and a brief review of the most commonly acquired linear eruptions following Blaschko's lines with the goal of expanding the histopathologic findings that may be encountered in adult blaschkitis. Blaschko’s lines were originally described by Dr. Females with X-inactivation and skin pigment differences will show it under UV light. Gov't. A recent study 20 reviewed thousands of photographs of congenital pigmentary disorders or vitiligo and defined the following three major patterns: (1) Blaschko's lines in narrow bands; (2) segmental "quadrilateral shapes"; and (3) nonsegmental "round shapes. French dermatologists Gourgerot and Carteaud first described confluent and reticulated papillomatosis in 1927 [1]. The nowadays well-known lines of Blaschko form streaks displaying a V-shape or fountain-like pattern on the back, an S-shape or whorled pattern over the lateral aspects of the trunk, and a linear pattern on. They are clinically important, as many inherited and acquired diseases follow these lines, making a characteristic visual appearance. They also run along the face above and below the eyes and over the ears. Linear atrophoderma of Moulin is a rare subtype of atrophic and pigmented linear morphoea. , incontinentia pigmenti). Cases of LP involving multiple segments of the body along the Blaschko’s lines with nail damage are rare, and the diagnosis was established based on dermoscopy and skin biopsy. Blaschko's lines represent a classic pattern of cutaneous mosaicism that can be observed in a wide variety of congenital and acquired skin disorders. This contribution reviews the clinicopathologic spectrum of skin lesions that follow Blaschko lines. The most widely accepted basis for these lines is. Blaschko’s lines are named after Alfred Blaschko, a German dermatologist who first described them in 1901. Discussion. The lines of Blaschko represent an pattern accepted by many different nevoid and acquired skin diseases on the human skin and mucosae and do not correspond to any know nervous, vesicular or lymphatic structures. Treatment is difficult and consists of avoidance of triggers and topical and systemic medications in order to. They become apparent when some diseases of the skin or mucosa manifest themselves according to these patterns. These lines are invisible under normal conditions. The cause of lichen striatus is unknown. When we start out as a single cell, and then a ball of cells, some of these cells become skin cells. The appearance of LPP in our case could not be directly linked to a specific cause because of the ambiguity in the pathogenesis of the disease. [French, from past participle of blaser, to cloy, from French dialectal, to be chronically hung over, probably from Middle Dutch blāsen, to blow up, swell; see bhlē- in. Fig. According to the affected skin com-ponents, epidermal nevi have been divided into organoid (with abnormal adnexal components, such as the hair follicles, seba-Seventeen cases of childhood discoid lupus erythematosus (DLE) have been previously reported in the literature.
