Why Is It Advisable to Avoid Scratching Scalp Psoriasis?

However, prior to engaging in their removal, it is imperative to consult with either a primary healthcare provider or a specialist dermatologist. The primary apprehension surrounding the elimination of flakes revolves around the potential of inadvertently tearing away healthy skin layers. This undesired outcome may give rise to heightened levels of pain, discomfort, and even the formation of scars. Furthermore, the act of picking at your scales carries the risk of exacerbating the size of the affected region.

What Is The Nature of Thick, Scaly Patches That Manifest on The Scalp, Indicative of Psoriasis?

Scalp Psoriasis Defined: This particular skin ailment arises due to the immune system's miscommunication, resulting in an accelerated growth of skin cells. These cells accumulate, forming noticeable patches, often adorned with white or silvery flakes. Notably, at least 50% of psoriasis sufferers experience this condition on their scalps.

Am I Suffering from A Scalp Fungus Infection Or Perhaps Psoriasis?

How can one effectively discern psoriasis from a fungal infection? An attentive examination of the reddish discolorations on the skin is key. If these patches exhibit a lustrous, silvery appearance, psoriasis may be the diagnosis. Conversely, if they manifest in the form of circular or ring-like patterns, a fungal infection is more probable.

How Can One Identify The Presence of Psoriasis Affecting The Scalp Area?

Indicators and manifestations of scalp psoriasis include:
The presence of reddish areas on the scalp, which may appear thickened and inflamed at times.
Flaking reminiscent of dandruff, accompanied by silvery-white scales that mimic dandruff in appearance.
A dry scalp condition that can deteriorate to cracking and subsequent bleeding.
Itching sensations ranging from mild to severe intensity.
Experiencing a burning feeling or soreness in the affected areas.
Temporary episodes of hair loss as a symptom.

Distinguishing between Scalp Eczema And Psoriasis: A Guide

In terms of visual manifestation, scalp eczema commonly manifests as a condition of dry, flaky skin accompanied by reddish discolorations on lighter skin tones, while for darker skin, it appears as grayish patches. In contrast, psoriasis exhibits a more pronounced and distinct layered appearance, with clearer demarcated edges compared to scalp eczema. Individuals affected by psoriasis might encounter scaly areas that exhibit a silvery, white, or red hue.

What Are The Methods to Detect Psoriasis on The Scalp?

Dermatological Evaluation Through Skin Sampling

In most instances, a dermatologist can accurately determine if a patient has psoriasis through a thorough skin examination. However, if further clarification is required to verify the diagnosis and eliminate potential alternative causes of the symptoms, such as eczema or cutaneous lupus, a skin biopsy may be undertaken.

What Are The Diagnostic Observations Made through Dermoscopy for Psoriasis?

During dermoscopic evaluation of plaque psoriasis utilizing a handheld dermoscope, one typically observes a regular pattern of dotted blood vessels within a reddish-pink backdrop, along with the presence of white scales (depicted in Figure 4) [7]. In certain instances, the backdrop may exhibit a grayish-white hue owing to the presence of extensively hyperkeratotic scales (illustrated in Figure 5).

What Are The Dermatoscopic Observations Associated with Psoriasis Affecting The Scalp?

The salient dermoscopic hallmarks of scalp psoriasis comprised of prominent red dots and globules, intricately twisted red loops, and distinct glomerular vessels. Conversely, seborrheic dermatitis exhibited a distinguishing feature of arborizing vessels and irregular red vessels, conspicuously lacking the presence of red dots and globules.

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
