Plaque psoriasis is a common skin condition characterized by raised, red patches covered with silvery-white scales. Dermatologists employ various methods for diagnosis.

Q: What is plaque psoriasis?

Plaque psoriasis is an autoimmune disorder that results in the rapid growth of skin cells, forming scaly plaques that can be itchy and painful. It often appears on the elbows, knees, scalp, and lower back.

Q: What are the common symptoms of plaque psoriasis?

• Red patches of skin covered with thick, silvery scales
• Dry, cracked skin that may bleed
• Itching, burning, or soreness
• Thickened or pitted nails
• Swollen and stiff joints (in some cases)

Q: How do dermatologists diagnose plaque psoriasis?

Dermatologists typically diagnose plaque psoriasis through:

• Visual Examination: A thorough examination of the skin to identify the characteristic plaques.
• Medical History: Gathering information on the patient’s medical history, including family history of psoriasis or related conditions.
• Dermoscopy: Using a dermatoscope to examine the skin in detail, which can help distinguish psoriasis from other skin conditions.
• Biopsy: In some cases, a skin biopsy may be conducted to rule out other skin disorders, ensuring an accurate diagnosis.

Q: What tests or procedures may be involved?

While most cases can be diagnosed through observation and patient history, dermatologists may employ:

• Blood Tests: To check for inflammation markers, although they aren’t specifically diagnostic for psoriasis.
• Patch Testing: To identify allergic reactions that may cause similar symptoms.

Q: Are there specific guidelines for diagnosis?

The diagnosis of plaque psoriasis often follows established clinical criteria, including:

• Identification of characteristic lesions on the skin.
• Assessment of the extent and severity of the plaques.
• Evaluation of the patient’s symptom history and quality of life concerns.
