Skin Diseases
Psoriasis
Psoriasis is a chronic inflammatory autoimmune skin disease that presents with redness, scaling and occasional itching. It most often appears on the scalp, knees and elbows, but it can also occur on other parts of the body. Its severity varies from person to person; in some people it is limited to small areas, while in others it can be more widespread. The goal of treatment is to provide the person with the best possible quality of life through personalized treatment plans.
What Is Psoriasis?
Psoriasis — whose medical name derives from the Greek word “psōra,” meaning “itch” or “scabies,” and which takes its Turkish name from the mother-of-pearl color of its lesions — is a fluctuating disease that arises when the immune system’s response to skin cells changes. Whereas skin cells normally renew over the course of weeks, in psoriasis this process speeds up, producing whitish, pearl-colored scaling on a reddened base at the skin’s surface. This picture can sometimes be accompanied by findings such as cracking, bleeding, itching or a burning sensation.
What Are the Types of Psoriasis?
The most common type is plaque psoriasis, which appears on the elbows, knees, scalp and lower back. However, there are also different subtypes that affect only the nails, the scalp or the skin folds:
- Psoriasis Vulgaris: Also called plaque psoriasis, this is the most common form of the disease. Its classic clinical findings are sharply demarcated, red (erythematous) and itchy plaques covered with silvery scales. It is often located on the scalp, knees, elbows and the flexural areas of the arms and legs.
- Guttate Psoriasis: A type marked by the sudden onset of small red plaques. It generally affects children or adolescents and is often triggered by tonsillitis.
- Pustular Psoriasis: A variant characterized by numerous pus-filled lesions that tend to merge.
- Erythrodermic Psoriasis: An emergency condition in which more than 90% of the total body surface is red and inflamed.
- Nail Psoriasis: The name given to cases in which the disease affects the nails, either together with the skin or in isolation.
What Causes Psoriasis?
Genetic predisposition, immune system mechanisms and environmental triggers (infections, cold/dry weather, sunburns, certain medications, trauma, smoking and alcohol, obesity, stress) combine to give rise to the disease.
How Does Psoriasis Start, and What Are Its Symptoms?
Sharply demarcated red plaques, white-silver scaling on top of them, itching/burning/tenderness, nail changes in some cases, and dandruff-like flaking on the scalp. In some patients this is accompanied by joint pain/swelling/stiffness (psoriatic arthritis).
Is Psoriasis Contagious?
It is absolutely not contagious — it does not spread by touch, by sharing items, or by using the same pool or sea.
How Is Psoriasis Diagnosed?
It is diagnosed through the clinical examination of a dermatologist; if needed, a skin biopsy or blood tests may be requested.
Which Diseases Enter the Differential Diagnosis of Psoriasis?
Atopic dermatitis, contact dermatitis, lichen planus, pityriasis rosea, mycosis fungoides, and body ringworm (tinea).
What Is the Treatment for Psoriasis, and How Is It Done?
Topical treatments (creams/ointments), systemic treatments (pills/injections), light therapies (phototherapy), and supportive treatments (moisturizers, lifestyle). Rather than a single miracle method, a holistic and personalized plan is the most appropriate approach.
Can Psoriasis Be Treated? Realistic Expectations and Long-Term Follow-Up
The question “Can I get rid of this disease completely?” is complicated by the misinformation online and by miracle cures that promise a “definitive solution.” Psoriasis is considered chronic, but with proper management long-term well-being is possible.
When Is Expert Support Essential?
If treatment is not responding, if the rash is spreading, if joint pain is present, or if social isolation/unhappiness is being experienced, an expert opinion should be sought.
Conclusion
“Getting rid of” psoriasis means removing it from the center of your life; this is possible with accurate information, patient follow-up and a balanced lifestyle.
Frequently Asked Questions
Does psoriasis recur?
Yes, psoriasis tends to recur by its very nature. However, with a proper follow-up protocol, the frequency and severity of these recurrences can be minimized, and long-term resolution is also possible.
Can psoriasis be cured with diet? What should patients eat or avoid?
Nutrition is a powerful tool that influences the immune system and inflammation. It is not a "medicine" on its own, but it is a very important pillar that supports the success of treatment.
Is sunlight good for psoriasis?
In most patients, controlled sunlight (the UV effect) is beneficial. However, exposure severe enough to cause sunburn can have the opposite effect and trigger psoriasis.
Can stress trigger psoriasis?
Stress is usually the strongest trigger that flares up existing psoriasis. In some people who have a genetic predisposition, a period of severe stress can set off the first episode.
