Lichen Nitidus Vs Keratosis Pilaris: Know the Differences

Lichen Nitidus Vs Keratosis Pilaris: Both lichen nitidus and keratosis pilaris are skin disorders that generate tiny bumps, however they are not the same. Keratosis pilaris, popularly known as "chicken skin," is more frequent and is distinguished by small, rough bumps on the upper arms, thighs, and buttocks. It is caused by keratin accumulation, a protein that creates hair and skin. Lichen nitidus, on the other hand, appears as flat-topped, glossy lumps on the wrists, ankles, and genitals. Lichen nitidus has an unknown origin, although it is not caused by keratin buildup.

What is lichen nitidus?

Lichen nitidus is a rare skin disease that causes small, glossy, flat-topped lumps on the genitals, wrists, and inner arms. These pimples are normally skin-colored or slightly pink, and they are not painful. Although its exact cause is unknown, it is not communicable and normally resolves on its own.

Key Features of lichen nitidus:

• Lichen nitidus is distinguished by flat, smooth, glossy papules - small lumps 1-2mm in diameter. They are usually skin-colored, although they can also be pinkish-white or pearly.

• Unlike keratosis pilaris, which frequently concentrates on certain locations, lichen nitidus can occur on any portion of the body. The flexor surfaces of the arms and legs, the chest, belly, and the genitals are all common places.

• Unlike keratosis pilaris, lichen nitidus usually does not cause any discomfort. This separates it even more and may make self-diagnosis more difficult.

• While the specific reason is unknown, lichen nitidus usually goes away on its own after a few months or years, making treatment unnecessary in the majority of instances.

Causes of lichen nitidus:

Although the specific cause of lichen nitidus is in doubt, various possibilities exist:

• It might be an autoimmune reaction in which the body targets its own skin cells.
• Some studies imply a relationship to viral illnesses such as Epstein-Barr virus.
• There might be a hereditary propensity to develop lichen nitidus.
• Emotional stress or trauma might potentially precipitate the disease.

Symptoms of lichen nitidus:

• Tiny, flat, shiny bumps, usually white or pale pink, often clustered on the genitals, wrists, forearms, and ankles.
• The bumps are usually painless and don't cause itching or burning.
• In some cases, the bumps may form streaks or lines.
• The condition usually resolves on its own within a few months to years.

What is keratosis pilaris?

Keratosis pilaris, or "chicken skin," is a common skin disorder in which dead skin cells accumulate and obstruct hair follicles, resulting in tiny, rough bumps. These bumps are most commonly found on the upper arms, thighs, and buttocks, although they can also arise on the face and in other places. It is not harmful and does not require treatment; however, moisturisers and moderate exfoliation can help enhance the look.

Key Features of keratosis pilaris:

• Keratosis pilaris is caused by an overabundance of keratin, a protein that forms the hair shaft and the outer skin layer. This accumulation clogs hair follicles, resulting in rough, bumpy papules.

• While lichen nitidus is more common, keratosis pilaris often affects the upper arms, thighs, buttocks, and even the face. Papules with a "goosebump" look are common.

• Unlike asymptomatic lichen nitidus, keratosis pilaris is frequently associated with itching, particularly owing to dryness and irritation. Scratching might aggravate the problem.

• Keratosis pilaris, unlike lichen nitidus, is a persistent disorder with no spontaneous remission. Treatments such as moisturisers, exfoliants, and topical medicines, on the other hand, can considerably enhance its look and control symptoms.

Causes of keratosis pilaris:

• Keratosis pilaris is caused by a buildup of keratin, a protein that forms the hair shaft and the top layer of the skin.
• This buildup forms tiny, rough bumps that resemble goosebumps.
• The condition is more common in people with dry skin, eczema, or a family history of keratosis pilaris.

Symptoms of keratosis pilaris:

• Tiny, rough bumps, often white, red, or brown, on the upper arms, thighs, buttocks, and cheeks.
• The bumps are usually painless but may cause mild itching or irritation.
• The condition is chronic but often improves with age and proper skincare.

Similarities between Lichen Nitidus and Keratosis pilaris

• Both diseases tend to be harmless and do not pose any severe health hazards.
• There is no treatment for Lichen Nitidus or Keratosis Pilaris, however symptoms may typically be treated.
• Both disorders can emerge in childhood, with Keratosis Pilaris being most frequent in youngsters.
• Lichen Nitidus and Keratosis Pilaris are also examples of primary localised skin ailments.
• Both illnesses may cause individuals to have cosmetic issues, leading to a need for therapy.

Both lichen nitidus and keratosis pilaris have rough skin, but a deeper examination shows significant distinctions. The more frequent relative, keratosis pilaris, appears as rough, often irritating papules on the upper arms, thighs, and buttocks. It is caused by an excess of keratin, the protein that makes hair and skin, which plugs hair follicles. Lichen nitidus, on the other hand, is distinguished by flat-topped, glossy papules that are commonly seen on the genitals, wrists, and ankles. While keratin accumulation is a factor, the specific aetiology remains unknown.The difference extends to distribution: keratosis pilaris likes large patches, whereas lichen nitidus prefers discrete clusters. The growth of lesions following scratch marks, known as koebnerization, separates lichen nitidus from its follicular cousin. So, the next time you see bumpy skin, remember that the devil is in the details, and a trained eye can distinguish the difference between lichen nitidus and keratosis pilaris despite their similar texture.
