What is Blaschkitis?

Blaschkitis is an acquired inflammatory dermatitis that some consider an adult variant of lichen striatus. In 1990, Grosshans proposed that blaschkitis was distinct from lichen striatus, identifying several criteria by which the 2 differ, including typical patient age, distribution, time course, and histopathology.

What causes lichen striatus?

The condition is triggered by an “immunologic reaction to an infection,” and that this results in a cascade of events including the methylation or demethylation of a portion of a “partially silenced genomic element.” Also, it has been reported that lichen striatus is triggered as a result of a viral infection of ...

Why is my eczema only on one side of my body?

Acquired blaschkoid dermatitis is unilateral — it only affects one side of the body. As its name would suggest, the skin lesions occur along Blaschko lines. The lesions may resolve spontaneously but they have a tendency to relapse over time, especially at times of stress.

Is lichen striatus curable?

Lichen striatus will go away on its own without treatment. This usually takes several months to a year. As the rash goes away, the bumps fade and may leave behind a lighter area of skin. This is not permanent.

What is Bronchitis? Causes, Signs and symptoms, Diagnosis and treatment.

Is lichen striatus an autoimmune disease?

Some scientists have suggested that lichen striatus is an autoimmune response to inflamed T cells. Environmental stimuli, such as infection or trauma, have also been implicated in its pathogenesis, as cases in unrelated individuals have been described.

Is lichen striatus genetic?

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.

Why have I suddenly got eczema?

Eczema triggers

Common triggers include: irritants – such as soaps and detergents, including shampoo, washing-up liquid and bubble bath. environmental factors or allergens – such as cold and dry weather, dampness, and more specific things such as house dust mites, pet fur, pollen and moulds.

Can Covid cause lichen striatus?

1 The same study also reported a female predominance of 90% in cutaneous reactions to COVID-19 vaccination. Adding to this body of evidence, we, herein, describe an eruption of lichen striatus occurring several days after COVID-19 vaccination in a middle-aged woman.

Is lichen contagious?

Lichen sclerosus isn't contagious and cannot be spread through sexual intercourse. Lichen sclerosus often occurs in postmenopausal women, but also in men and children. In women, lichen sclerosus usually involves the vulva.

How do I know if my rash is fungal or bacterial?

Skin infections caused by viruses usually result in red welts or blisters that can be itchy and/or painful. Meanwhile, fungal infections usually present with a red, scaly and itchy rash with occasional pustules.

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).

Does lichen Nitidus go away?

For most people, lichen nitidus lasts for a few months to a year. The condition usually clears up on its own without treatment. After it clears up, the appearance of the skin is usually normal with no scarring or permanent change to skin color.

What causes blaschko?

The cause of the distribution pattern is unknown. It is possibly a form of human 'mosaicism' where certain specific cells or groups of cells react differently from other cells due to chromosomal abnormalities. The embryological explanation of Blaschko's lines is not at all clear.

Does eczema ever go away?

Eczema typically develops in early childhood and in a small number of cases spontaneously resolves on its own. For everyone else, eczema is usually a lifelong skin condition. While scientists have yet to find a cure, there are treatments and ways to manage your eczema to minimize flare-ups.

Can weak immune system cause eczema?

Is eczema caused by a weak immune system? Eczema isn't believed to be the result of a weak immune system. But researchers don't know exactly what causes eczema, according to the National Eczema Association (NEA). Experts think genes and a variety of triggers are contributing factors.

Anyone with eczema has inherently dry skin and is susceptible to weaker skin barrier function. Therefore, drinking water (especially around exercise) to keep the body and skin hydrated is recommended.

Does stress cause eczema?

When too much cortisol is released due to chronic or severe stress, it can dysregulate the immune system and cause an inflammatory response in the skin.

What causes linear skin lesions?

The causes for occurrence in a linear pattern include lesions following Blaschko′s lines, blood vessels, lymphatics and dermatomes; due to Koebner′s phenomenon and auto inoculation; external factors; infestations like cutaneous larva migrans and burrows of scabies.

What does a linear rash mean?

Linear epidermal naevi

They are thought to be due to point mutations in keratin genes causing malformation in the epidermis. They may be present at birth or develop in infancy. At first they appear as flat, itchy, pigmented plaques but may increase in size and develop a thickened warty surface.

What does Phytophotodermatitis mean?

Phytophotodermatitis (PPD) is a cutaneous phototoxic inflammatory eruption resulting from contact with light-sensitizing botanical substances, also known as furanocoumarins, and long-wave ultraviolet A (UV-A, 320-380 nm) radiation.
