What Vitamin Insufficiency Is Linked to The Development of Lichen Planus?

A deficiency in serum vitamin B12 can be attributed to oral lichen planus. This vitamin is intricately connected with the optimal functioning of both the immune and neuropsychological systems, both of which are pivotal in the etiopathogenesis and potential malignant transformation of oral lichen planus. August 21, 2020.

What Lies at The Foundation of The Onset of Lichen Planus?

This is a condition of an unknown origin, denoted as idiopathic, which triggers irritation within the skin layers. In the context of lichen planus, the immune system of the individual mistakenly targets certain bodily components rather than safeguarding the body against external threats such as bacteria or viruses.

Is It Possible for Lichen Planus to Be A Lifelong Condition?

The majority of skin lichen planus cases tend to resolve spontaneously within a timeframe of 6 to 9 months. Rarely does the rash persist for a duration exceeding 18 months. Nevertheless, it's noteworthy that oral lichen planus and its manifestation in the genital region may exhibit a more prolonged and persistent nature.

What Type of Medication Is Typically Prescribed for The Treatment of Lichenoid Keratosis?

Addressing Benign Lichenoid Keratosis Condition
Application of Anti-Itch Cream -- to alleviate pruritus
Administration of Steroidal Medication, Both Orally and Topically -- to mitigate inflammatory symptoms
PUVA Therapy or Photochemotherapy Approach -- an innovative treatment modality employing ultraviolet radiation for sore management
Retinoid Acid Therapy -- a Vitamin A-based medication, frequently prescribed for acne vulgaris treatment
Date:

What Are The Potential Drugs That Might Lead to The Development of Lichenoid Keratosis?

Drugs frequently implicated in eliciting a lichenoid drug-induced skin reaction encompass a variety of medications such as: Blood pressure medications like ACE inhibitors, beta-adrenergic blocking agents, nifedipine, and methyldopa. Additionally, diuretic agents such as hydrochlorothiazide, furosemide, and spironolactone are also known to precipitate this reaction. Moreover, non-steroidal anti-inflammatory drugs (NSAIDs) are among the medications that have been commonly reported to trigger such eruptions.

What Conditions Could Potentially Be Erroneously Identified As Lichen Planus?

Occasionally, lichen planus can be erroneously identified as alternative dermatological conditions, including lichen sclerosus, which underscores the importance of consulting a skin expert (dermatologist) or a specialist in women's health (gynecologist) for accurate diagnosis.

Is There A Risk of Keratosis Transforming into A Malignant Condition?

Actinic keratosis represents an irregular proliferation of cells, stemming from prolonged exposure to the sun's harmful rays, he elaborates. While these lesions are non-malignant in nature, a minor percentage of them poses a risk of evolving into skin cancer.

What Are The Factors That Initiate A Lichenoid Response?

The emergence of prototypical cutaneous lichenoid reactions as a result of medication intake can be attributed to various agents, including angiotensin-converting enzyme (ACE) inhibitors, antimalarial medications, beta-adrenergic blocking agents, gold compounds, lithium salts, mercury amalgam fillings, methyldopa, penicillamine derivatives, quinidine sulfate, sulfonylurea-based drugs for diabetes management, thiazide-class diuretics, inhibitors of tumor necrosis factor (TNF)-α, as well as tyrosine kinase inhibitors.

What Comprises The Six Distinct Classifications of Lichen Planus?

Categorization of oral lichen planus encompasses six distinct clinical manifestations: reticulate, plaque-mimicking, papular, atrophic/erosive, ulcerated, and bullous forms, as illustrated in Figure 1. These types predominantly impact the buccal mucosa, tongue, and gingival tissues.

What Distinguishes Lentigo Maligna from Lichenoid Keratosis, And How Do They Vary from Each Other?

In the context of lichenoid keratosis, the grayish specks encircling the follicular apertures are characteristically rough, uniform, and prevalent, whereas within lentigo maligna, these dots are markedly finer and concentrated in specific areas.

Cleaning your dermoscopy after usage is important to prevent cross-contamination and infection. The cleaning method may vary depending on the type and model of your dermoscopy, so you should always follow the manufacturer’s instructions. However, some general steps are:

• Turn off and disconnect your dermoscopy from any power source or device.

• Wipe off any visible dirt or debris from the dermoscopy with a soft cloth or tissue.

• Disinfect the dermoscopy with an alcohol-based wipe or spray, or a disinfectant solution recommended by the manufacturer. Make sure to cover all surfaces, especially the lens and contact plate.

• Let the dermoscopy air dry completely before storing it in a clean and dry place.

• Do not use abrasive or corrosive cleaners, solvents, or detergents that may damage the dermoscopy.

• Do not immerse the dermoscopy in water or any liquid, unless it is waterproof and designed for immersion.

You should clean your dermoscopy after each use, or at least once a day if you use it frequently. You should also check your dermoscopy regularly for any signs of damage or malfunction, and contact the manufacturer or service provider if needed.

A dermoscopy is a device that allows the examination of skin lesions with magnificationand illumination. By revealing subsurface structures and patterns that are not visible tothe naked eye. It can improve the diagnose accuracy of skin lesions, such as melanoma,basal cell carcinoma, seborrheic keratosis, etc.

There are two main types of dermoscopy: Non polarized and polarized dermoscopy.We’ve fitted most of our dermoscopys with polarized and non-polarized light. They canbe used in multiple skin structures.

Non-polarized contact Mode

In non-polarized mode, the instrument can provide information about the superficialskin structures, such as milia-like cysts, comedo-like openings, and pigment in theepidemis.

The dermoscopy requires applying a liquid such as mineral oil or alcohol to the skin andplacing the lens in contact with the skin. This reduces surface reflection and enhancesthe view of subsurface structures.

Polarized contact Mode

In polarized mode, the instrument allows for visualization for deeper skin structures,such as blood vessels, collagen, and pigment in the dermis.

The dermoscopy does not need to be in contact with the skin or use any liquid. Theirpolarized light can help to eliminate surface reflection and allow visualization ofvascular structures.

Polarized non-contact Mode

The dermoscopy can also use polarized light to examine the skin without direct contact.

In polarized non-contact mode, the instrument allows for examination infected areasand lesions that are painful for the patient, or the difficult to contact pigmented lesions,such as nails and narrow areas.

The contact plate should be removed in this mode, and it does not require applying aliquid to the skin. As it doesn’t require pressure or fluid application on the skin, it canalso avoid cross-contamination and infection risk.

Compared with visual inspection, the dermoscopy can be used to capture and store skin lesion photos, which play an important role in early skin cancer examination.

The dermoscopy allows the examination of skin lesions with magnification and illumination. This can be greatly avoiding the factors that cause interference to visual detection. Such as lighting, skin color, hair and cosmetics.

Several studies have demonstrated that dermoscopy is useful in the identification of melanoma, when used by a trained professional.

It may improve the accuracy of clinical diagnosis by up to 35%
It may reduce the number of harmless lesions that are removed
In primary care, it may increase the referral of more worrisome lesions and reduce the referral of more trivial ones

A 2018 Cochrane meta-analysis published the accuracy of dermoscopy in the detection.

Characteristics of the dermatoscopic structure of the skin lesions include:

• Symmetry or asymmetry
• Homogeny/uniformity (sameness) or heterogeny (structural differences across the lesion)
• Distribution of pigment: brown lines, dots, clods and structureless areas
• Skin surface keratin: small white cysts, crypts, fissures
• Vascular morphology and pattern: regular or irregular
• Border of the lesion: fading, sharply cut off or radial streaks
• Presence of ulceration

There are specific dermoscopic patterns that aid in the diagnosis of the following pigmented skin lesions:

• Melanoma
• Moles (benign melanocytic naevus)
• Freckles (lentigos)
• Atypical naevi
• Blue naevi
• Seborrhoeic keratosis
• Pigmented basal cell carcinoma
• Haemangioma
