Psoriasis: A Common Skin Disorder

Psoriasis is one of the most common skin conditions in the world, affecting people of all ages. It is characterized by raised plaques of inflamed, red skin and white scales that can "flake off" [7]. The condition causes itchy, dry patches on the skin, which can be unsightly and uncomfortable.

Symptoms

The symptoms of psoriasis include:

• Raised plaques of inflamed, red skin
• White scales that can flake off
• Itching or burning sensation on the skin
• Dry, scaly patches on the skin

Who Gets Psoriasis?

Psoriasis affects 2-4% of males and females, with onset peaks at 15-25 years and 50-60 years. It tends to persist lifelong, fluctuating in extent and severity [11].

Early Signs of Psoriasis

According to Dr. Lonowski, early signs of psoriasis include an onset of a scaly, sometimes itchy rash that is pink in color with a thick white scale on top [7]. This can be a subtle indication of the condition, but it's essential to note that symptoms can vary from person to person.

Common Symptoms

Some common symptoms of plaque psoriasis (the most common type) include:

• Raised, discolored plaques with a white or silvery surface
• Cracks (fissures)
• Bleeding

These symptoms can appear on various parts of the body, including the scalp, elbows, knees, and lower back [10].

Other Possible Symptoms

In addition to these common symptoms, other possible signs of psoriasis include:

• Heel pain
• Swelling in your leg
• Stiffness

It's essential to consult a healthcare provider for an accurate diagnosis and treatment plan. They will examine the affected areas, ask about symptoms, family history, and provide guidance on managing the condition [10].

Diagnostic Tests for Psoriasis

To diagnose psoriasis, a dermatologist will examine your skin, nails, and scalp for signs of this condition [7]. This physical examination is usually the first step in diagnosing psoriasis. The doctor may also ask questions about your health and medical history to determine if you have any underlying conditions that could be contributing to your symptoms.

The diagnostic tests for psoriasis typically involve a combination of:

• Physical examination: A dermatologist will examine your skin, nails, and scalp for signs of psoriasis, such as thick, red, scaly patches.
• Skin biopsy: In some cases, a doctor may recommend a biopsy to confirm a psoriasis diagnosis. This involves removing a small sample of skin tissue from the affected area and examining it under a microscope.

It's worth noting that there are no blood tests that can diagnose psoriasis [9]. However, after performing a physical examination, a doctor may order a biopsy to confirm a psoriasis diagnosis.

Topical Corticosteroids for Mild Psoriasis

Topical corticosteroids are a common treatment option for mild and limited psoriasis. They can be effective in reducing plaque formation and alleviating symptoms such as itching and inflammation.

• According to search result [8], topical medications, including corticosteroids, can usually effectively treat mild plaque psoriasis.
• Topical steroids, like hydrocortisone 1%, are a low-dose option that's great for mild cases of psoriasis (search result [9]).
• A study found that among various treatments, topical antipsoriatics were used by 20% of males and females alike to treat their psoriasis symptoms (search result [10]).

These corticosteroids work by downregulating pro-inflammatory cytokines coding genes, which helps reduce inflammation and slow down skin cell production. They are often the first line of treatment for mild cases of psoriasis and can be applied directly to the affected skin area.

Differential Diagnoses of Psoriasis

Psoriasis, a chronic skin condition characterized by thick, red, and scaly patches, can be challenging to diagnose due to its similarity with other dermatological conditions. According to various studies [7][8], the principal differential diagnoses for psoriasis include:

• Pityriasis lichenoides chronica: A rare skin condition marked by small, scaling spots that can resemble psoriatic plaques.
• Secondary syphilis: A sexually transmitted disease that can cause a rash on the palms of the hands and soles of the feet, which may be mistaken for psoriasis.
• Tinea corporis: A fungal infection of the skin that can cause circular patches with clear centers, similar to psoriatic plaques.

These conditions require careful consideration in the differential diagnosis of psoriasis. It is essential to rule out these and other conditions through a thorough medical examination and diagnostic tests before confirming a diagnosis of psoriasis [7].
