Utilizing Dermoscopy to Assess Characteristic Manifestations of Psoriasis
Dermoscopy is an effective tool to evaluate psoriasis across different affected areas of the skin. Typical dermoscopic features of psoriatic lesions include:
Scalp psoriasis: Red dots, globules, and twisted looping vessels are visible.
Nail psoriasis: Changes like onycholysis, salmon patches under the nail, and splinter hemorrhages can be observed.
Inverse psoriasis: Dotted vessels on a reddish backdrop are apparent.
Dotted vessels are the most common dermoscopic vascular marker in psoriatic plaques.
Psoriasis manifests as raised, scaly red inflammatory patches with distinct borders. It frequently affects the scalp, trunk, buttocks, and limbs, though it can appear anywhere on the skin. Using a dermatoscope facilitates detailed visualization of microscopic manifestations of this chronic condition. Dermoscopy is valuable for determining disease extent and monitoring treatments.
How Dermoscopy Can Be Utilized in Diagnosing And Evaluating Psoriasis
Dermoscopy is an important non-invasive technique that aids visual diagnosis of psoriasis across different body areas. Using a dermatoscope provides magnified visualization and documentation of distinct characteristics:
Scalp psoriasis: Red dots, globules and twisted vessels are visible
Nail psoriasis: Signs like salmon patches, onycholysis, splinter hemorrhages
Pustular psoriasis: Dotted vessels surrounded by white/yellow pustules
Palmoplantar: Yellow scales, orange dots, pronounced vessels
Other common dermoscopic markers seen in psoriatic plaques include sharply demarcated borders, white scaling, and dull red erythema.
Dermoscopic evaluation improves detection of subtle signs and extent of involvement. It helps determine if a skin biopsy is needed for further confirmation in ambiguous presentations. Overall, incorporating dermoscopy with clinical inspection grants a superior assessment of this chronic papulosquamous disease. Sequential documentation aids in gauging treatment efficacy as well.

On a light red backdrop, SD was identified by the patchy distribution of yellow scales and dotted vessels, while PR was distinguished by the peripherally placed white scales and the patchy distribution of dotted vessels on a yellowish background.
Dermoscopy is used to identify diseases like Bowen's disease. Glomerular veins and a scaly surface are the most common dermoscopic characteristics of Bowen's disease.
With their characteristic bluish-pink color, asymmetric arborizing vasculature, and focal ulceration, superficial basal cell carcinomas are often diagnosed by skilled dermoscopists. White regions of regression and little scaling could also exist.
whereas scaly erythematous patches with itching can be the appearance of either disease1, psoriasis typically coexists with lesions on the extensor areas, whereas seborrheic dermatitis affects other skin regions rich in sebaceous glands, such as the ears, eyebrows, central chest, and intertriginous areas.
Biopsy of the SkinYour dermatologist can typically identify psoriasis simply by looking at your skin. In the event that additional information is required to validate the diagnosis and exclude alternative etiologies of symptoms, such as cutaneous lupus or eczema, a skin biopsy might be conducted.
Your doctor will typically check your nails, scalp, and skin for symptoms of psoriasis in order to make the diagnosis. Inquiries concerning your health, medical history, and family history could also be made, including whether you: Feel sensations like skin that is burning or itching. had a recent illness or undergone a stressful event.
The following symptoms may manifest as plaque psoriasis: Thick, elevated skin patches known as plaques. Certain plaques are covered in scale, a thin, dried layer of silvery white paint. Various-sized plaques.
characteristics of the dermis. Beautiful collarette of scales with brown globules (white arrow), middle yellow with a reddish background, peripheral dotted vessels with patchy distribution (black circle), and the plaque's periphery attached to red arrows.
Evaluation of scalp psoriasis by trichoscopic meansRed spots and uniformly distributed globules are seen at low magnifications. White or white-silver dry scales are a common discovery. Recently, indications supporting the diagnosis of psoriasis have been identified, including hidden hair and signet ring vessels.
When psoriasis lesions were examined under a dermoscopy, 76.3% (29/38) showed diffuse scaling, 60.5% (23/38) showed white scales, and 76.3% (29/38) showed dotted vessels along with a regular distribution of vessels; in hand eczema lesions, 78.5% (11/14) showed diffuse scaling, and 57.1% (8/...) showed white and yellow scales.

I completed my dermatological training just as dermoscopy was starting to gain popularity. The evidence for improved diagnosing skills is now overwhelming. Throughout my multiple courses at the AAD and other locations, I consistently felt more perplexed and overwhelmed than before. I discovered there was no mechanism for me to "train" myself and receive feedback. This book is different in that it teaches you how to identify traits and then apply them in a self-directed course. It may be completed one chapter at a time and is well written. I feel like I've learned enough about this significant advancement in melanoma diagnosis after enough repetition.

For those interested in dermatology, this book is helpful and contains many examples; nonetheless, it is overly dense with formulas and tables. An excellent dermatology atlas is also essential for learning dermatology.(z.B. Marghoob, Braun, Atlas of Dermoscopy..)

I self-trained using this book. It's quite explicit and colorful.
