What is blaschko's lines?

Blaschko's lines, also called the lines of Blaschko, are lines of normal cell development in the skin. These lines are invisible under normal conditions, but can become apparent as whorls, patches, streaks or lines in a linear or segmental distribution over the skin due to a mosaic skin condition.

What causes Blaschko's lines to be visible?

This rare phenomenon is referred to a genetic mosaicism. 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.

Is there a way to see blaschko lines?

To the human eye they are invisible, but they can be seen under UV light. The lines were discovered by German dermatologist Alfred Blaschko 75 years ago, Dr Bav Shergill, of the British Association of Dermatologists told MailOnline.

What do Blaschko stripes look like?

Blaschko Lines follow the same pattern on all people. They run down the arms and legs. They curve around the sides, like tiger stripes. On the chest and upper back they rise in a swirl before dipping down to meet in a deep “v” along the spine and the middle of the chest.

What is Blaschkoid?

Acquired blaschkoid dermatitis is a rare skin condition of unknown cause. It was first described in 1990 by Grosshans and Marot in Bordex, France. It is also known as Blaschkitis, or, idiopathic dermatitis along the lines of Blaschko. It may represent the adult form of lichen striatus.

Blaschko's Lines - Do humans have stripes like a tiger or zebra?

How do you treat Blaschkitis?

Treatment options discussed with the patient include observation and topical corticosteroids. The patient elected to apply high potency betamethasone dipropionate 0.05% twice daily. A near-complete resolution of his skin lesions was observed after two weeks of treatment (Figures ​3-​4).

Are blaschko lines Dermatomes?

The lines of Blaschko are to be distinguished from dermatomes, Voigt's lines (borders between areas of innervation by peripheral cutaneous nerves), Langer's lines of cleavage, embryonic clefts, and pigmentary demarcation lines. Defects arising from neural crest abnormalities should not be mistaken for Blaschko's lines.

Can cats see your blaschko lines?

They're called Blaschko's Lines and are in our genetic code and can only be seen under UV light! They're usually a V Pattern that kind of swirls down our backs and wraps up our neck and around our arms. Supposedly cats can see our stripes! Yep...

Can you see blaschko lines under UV light?

In the episode, what the investigator discovered was something called Blaschko's lines. These swirling patterns are found on the backs of many chimeras. Often you need UV light to see them. These patterns arise from the fact that chimeras start out with two cells, each with different DNA.

Can cats see your blaschko stripes?

To the human eye they are invisible, but they can be seen under UV light. And some people with a genetic mutation have stripes clearly visible. The stripes were discovered by German dermatologist Alfred Blaschko 75 years ago. Also since cats and dogs can see UV light they can see our stripes.

What are tiger stripes on a woman?

Many ladies describe their stretch marks as tiger stripes that they feel they've earned through being such courageous females and mothers.

Is Blacklight harmful to humans?

Exposure to UVA from black lights is well below the recognised safe limits and is not hazardous to people using them, working in their vicinity or who have them in their home. Exposure from black lights would be much lower than your exposure to UVA outdoors.

Can dogs see UV light?

UV light is invisible to the human eye and it was thought that other mammals could not see ultraviolet wavelengths because their eye lenses were so similar to humans. However, like those in the animal kingdom able to see these wavelengths (like birds, fish and some reptiles), cats and dogs posses UV-transparent lenses.

Can animals See Blaschko's lines?

The stripes are a type of genetic mosaicism. They do not correspond to nervous, muscular, or lymphatic systems. The lines can be observed in other animals such as cats and dogs. Alfred Blaschko is credited with the first demonstration of these lines in 1901.

What is linear Lichen Planus?

Linear lichen planus (LLP) is a rare form of lichen planus, which is a condition that affects the skin and/or mouth. In LLP, specifically, affected people develop itchy, purple, flat-topped papules (bumps) in a linear distribution along the lines of Blaschko.

Can cats see humans stripes?

Psychedelic stripes, colors and patterns on flowers, birds and bugs are just some of the things that cats can see that humans cannot.

What animals can see UV light?

Do cats see humans as parents?

Oregon State University researchers concluded that cats really do actually love their humans — or at the very least, see them as parents or caregivers — after conducting a study on kittens, modelled after previous research on dogs and babies.

Do black lights hurt cats eyes?

Ultraviolet or black light is invisible to humans, so if a room was lit entirely by UV, it would be completely dark to us. This is because the lens in the human eye blocks UV. Most other mammals, including cats, dogs, and monkeys, have lenses that permit ultraviolet transmission.

What do cats see when they look at humans?

A cat's vision is similar to a human who is color blind. They can see shades of blue and green, but reds and pinks can be confusing. These may appear more green, while purple can look like another shade of blue. Cats also don't see the same richness of hues and saturation of colors that we can.

What is linear psoriasis?

Linear psoriasis is an unusual clinical variation of psoriasis that manifests segmentally along the lines of Blaschko. A major differential diagnosis is inflammatory linear verrucous epidermal nevus (ILVEN).

How do you get lichen striatus?

The cause of lichen striatus is unknown. Possibly genetic factors or environmental triggers have a role to play in its development. The eruption affects the lines of Blaschko, which are thought to be embryonic in origin. Over 50% of cases occur in children aged between 5 and 15 years.

What is lichen Nitidus?

Lichen nitidus is an uncommon, inflammatory skin condition. It appears as small, skin-colored, raised bumps (papules). Lichen nitidus (LIE-kun ni-TIE-dus) is a rare skin condition that usually appears as tiny, skin-colored, glistening bumps on the surface of your skin.

Can dogs sense evil?

They also have a superb knack of sensing things such as illness, emotions, and goodness or evilness. Many dogs show their ability to sense good or evil when they meet a new person. Even if the person puts on an act and makes out that they are good, if they are evil, dogs can work this out with ease.

What does it mean when my dog stares at me for a long time?

Just as humans stare into the eyes of someone they adore, dogs will stare at their owners to express affection. In fact, mutual staring between humans and dogs releases oxytocin, known as the love hormone. This chemical plays an important role in bonding and boosts feelings of love and trust.
