Psoriasis Description

Psoriasis is an autoimmune condition that causes inflammation in your skin, leading to thick areas of discolored skin covered with scales [2]. This chronic disease is characterized by the rapid buildup of skin cells, which can cause red or discolored, scaly, and itchy patches on the skin [8].

Common Symptoms

The symptoms of psoriasis include:

• Thick, red, well-defined patches of skin
• Skin redness and irritation
• Flaky patches of skin that form scales
• Itchy, red skin plaques

These symptoms can appear on various parts of the body, including the knees, elbows, trunk, scalp, hands, feet, genitalia, and ears [1, 5, 7, 10].

Key Facts

• Psoriasis is a chronic disease where skin cells build up quickly.
• The condition causes inflammation in the skin.
• Symptoms can include red or discolored patches, scales, and itchiness.

Common Signs and Symptoms of Psoriasis

Psoriasis is a chronic skin condition that can cause a range of symptoms, including:

• Dry, thick, and raised patches on the skin: These patches are often covered with a silvery-white coating called scale [1].
• Flaky patches of skin: Some people experience flaky patches of skin, which form silvery-white or grey scales [3].
• Itching or soreness: Psoriasis can cause itching or soreness in some individuals.
• Skin rashes or patches: These may start as small bumps and turn into larger patches that are red, dark pink, or purple [5].

Additional Symptoms

In some cases, psoriasis can also lead to:

• Joint pain, stiffness, and swelling: Psoriatic arthritis is a condition where the joints become inflamed, leading to pain, stiffness, and swelling [6].
• Itchy scalp: Some people may experience an itchy scalp due to psoriasis.
• Dry or rough skin: Psoriasis can cause dry or rough skin in some individuals.

To diagnose psoriasis, your doctor will typically perform a physical examination of your skin, scalp, and nails for signs of the condition [2]. They may also ask questions about your health history and symptoms [2].

In some cases, a dermatologist may order a biopsy to confirm a diagnosis of psoriasis, especially if they are unsure based on the physical exam alone [7]. However, there are no specific blood tests that can diagnose psoriasis [7].

It's worth noting that joint x-rays or bone scans may be used to diagnose psoriatic arthritis, which is a related condition that affects some people with psoriasis [5]. However, these tests are not typically used for diagnosing psoriasis itself.

The diagnosis of psoriasis is often made based on the appearance of characteristic skin lesions and symptoms such as redness, scaling, and itching. A healthcare provider or dermatologist will diagnose psoriasis after a physical exam and may use other diagnostic tools to confirm the diagnosis [8].

Treatment Options for Psoriasis

Psoriasis is a chronic skin condition that can be managed through various treatment options. The goal of treatment is to reduce the severity of symptoms, slow disease progression, and improve quality of life.

• Topical Treatments: Topical corticosteroids are often used as a first-line treatment for mild and limited psoriasis. They can reduce plaque formation and inflammation [6]. Other topical agents include salicylic acid, coal tar, vitamin D analogues, retinoids, and calcineurin inhibitors [4].
• Methotrexate: Methotrexate is an effective treatment option for severe psoriasis, psoriatic arthritis, and nail psoriasis. It works by slowing down the production of skin cells and suppressing inflammation [2]. Most patients see a reduction in psoriasis symptoms within four to six weeks [9].
• Biologics: Biologic medications target specific parts of the immune system and can be effective for moderate to severe psoriasis. They work by blocking certain cells or proteins that play a role in psoriasis [8].
• DMARDs: Disease-modifying antirheumatic drugs (DMARDs) may relieve more severe symptoms and attempt to slow or stop joint and tissue damage and the progression of psoriatic arthritis [3].

Medications for Psoriatic Arthritis

In addition to treating psoriasis, medications can also help manage psoriatic arthritis. DMARDs, such as methotrexate, can be effective in relieving symptoms and slowing disease progression [3]. Biologics, like apremilast, can also provide strong treatment for plaque psoriasis and psoriatic arthritis [5].

Differential Diagnoses of Psoriasis

Psoriasis, a chronic inflammatory skin disease, can be challenging to diagnose due to its various clinical manifestations. When considering the differential diagnosis of psoriasis, several conditions must be ruled out to ensure accurate treatment and management.

• Pityriasis Rosea: A common condition characterized by an initial "herald patch" followed by a widespread eruption of scaly patches. It is often confused with psoriasis due to its similar appearance.
• Maculopapular Drug Eruptions: Certain medications can cause skin reactions that resemble psoriasis, including maculopapular eruptions.
• Pityriasis Rubra Pilaris (PRP): A rare genetic disorder characterized by scaly, red patches on the skin. PRP can be mistaken for psoriasis due to its similar appearance.
• Lichen Planus: An inflammatory condition that affects the skin and mucous membranes, often causing purplish, itchy patches.
• Discoid Lupus Erythematosus (DLE): A chronic autoimmune disorder that causes scaly, red patches on the skin, particularly on the face and ears.

These conditions can be difficult to distinguish from psoriasis due to their similar clinical presentations. However, a thorough medical history, physical examination, and diagnostic tests such as biopsy or dermoscopy can help rule out these differential diagnoses and confirm a diagnosis of psoriasis (see [3], [6], [7], [11]).
