Psoriasis Types

There are several types of psoriasis, including:

• Plaque Psoriasis: This is the most common type, causing itchy, dry, and raised skin patches.
• Nail Psoriasis: When the nails on your hands or feet are affected, they can become thickened, discolored, or separated from the nail bed.

These types of psoriasis can vary in severity and may be triggered by different factors. [4][5]

Common Signs and Symptoms of Psoriasis

Psoriasis typically causes flaky patches of skin, which form silvery-white or grey scales. Some people find their psoriasis causes itching or soreness.

• Flaky patches of skin with silvery-white or grey scales
• Itching or soreness in the affected areas

These symptoms can appear on various parts of the body, including the elbows, knees, scalp, trunk, palms, and soles of the feet. If you're experiencing any of these symptoms, it's essential to consult a healthcare professional for proper diagnosis and treatment.

Diagnostic Tests for Psoriasis

Psoriasis diagnosis involves a combination of clinical examination, medical history, and sometimes additional tests to confirm the condition. According to [3], a biopsy is a test in which a pathologist examines skin cells under a microscope to determine whether psoriasis is the cause of symptoms.

A biopsy can help diagnose psoriasis by examining skin cells from a small sample of skin tissue removed from the affected area. This test can be performed by a dermatologist or primary care doctor, as mentioned in [3].

While there are no definitive lab tests for diagnosing psoriasis, a biopsy can provide valuable information to confirm the condition. Additionally, other tests like CBC count, blood urea nitrogen (BUN)/creatinine, liver function tests (LFTs), hepatitis panel, tuberculosis (TB) screening, and others may be ordered to rule out other conditions that may present similar symptoms [6].

It's essential to note that a biopsy is usually not the first line of diagnosis for psoriasis. A clinical examination by a dermatologist or primary care doctor is typically sufficient to diagnose the condition [3].

Treatment Options for Psoriasis

Psoriasis, an autoimmune condition that causes red, itchy patches on the skin, can be effectively managed with various treatment options. According to recent studies and medical guidelines, here are some key points about drug treatments for psoriasis:

• DMARDs (Disease-Modifying Antirheumatic Drugs): These medications may relieve more severe symptoms and attempt to slow or stop joint and tissue damage and the progression of psoriatic arthritis [4].
• Topical Agents: Topical corticosteroids, salicylic acid, coal tar, vitamin D analogues, retinoids, calcineurin inhibitors, and other topical agents are commonly used to treat mild to moderate psoriasis [6].
• Biologics: Biologic medications, such as infliximab, bimekizumab, ixekizumab, and risankizumab, have been shown to be effective in treating moderate to severe plaque psoriasis [8].

Commonly Prescribed Medications

According to a recent study, the most commonly prescribed medications for treating mild to moderate psoriasis include:

• Topical corticosteroids (35% of male patients and 21% of female patients)
• Miscellaneous topical agents (35% of male patients and 13% of female patients)
• Topical antipsoriatics (20% of both male and female patients)

Important Considerations

When considering drug treatment for psoriasis, it's essential to consult with a healthcare provider to determine the best course of treatment based on individual needs and medical history.

Differential Diagnoses of Psoriasis

Psoriasis, a common chronic inflammatory skin disease, can exhibit various clinical manifestations, making differential diagnosis essential for accurate treatment and management.

• Guttate Psoriasis: Typically presents as an acute onset of small, erythematous papules on the trunk, arms, and legs. [4]
• Pityriasis Rosea: A common skin condition characterized by a herald patch followed by a secondary eruption of oval-shaped, scaly patches. [5]
• Maculopapular Drug Eruptions: A type of drug reaction that presents as a maculopapular rash, which can be similar to psoriasis. [5]
• Pityriasis Rubra Pilaris: A rare skin condition characterized by small, scaly papules and plaques, often accompanied by palmoplantar keratoderma. [11]

Other Differential Diagnoses

• Bowen Disease: A type of squamous cell carcinoma that can present as a solitary, scaly patch or plaque.
• Discoid Lupus Erythematosus: An autoimmune disease characterized by chronic inflammation and scarring lesions on the face and scalp.
• Drug Eruptions: Various types of skin reactions to medications, which can mimic psoriasis.
• Erythema Annulare Centrifugum: A rare skin condition characterized by a ring-shaped erythematous patch or plaque.
• Lichen Planus: An inflammatory skin disease that presents as flat-topped, polygonal papules and plaques.

Important Considerations

Differential diagnosis of psoriasis is crucial to avoid misdiagnosis and ensure proper treatment. A thorough medical history, physical examination, and sometimes histopathological examination are necessary to confirm the diagnosis. [14]
