Psoriasis

Psoriasis is a chronic autoimmune condition that speeds up the normal life cycle of skin cells, causing thick, red, scaly plaques that may itch or crack. The condition most often affects the scalp, elbows, knees, and lower back, but it can appear anywhere on the body. Some patients also develop psoriatic arthritis, which causes joint pain and stiffness.

At The Medical Group of New Jersey, our dermatologists combine advanced medical treatments with a compassionate approach to help patients control flares, protect joint health, and improve overall quality of life.

Symptom Onset & Initial Evaluation

Psoriasis symptoms can come and go, often flaring in response to stress, illness, or certain medications. Common signs include:

• Red, raised patches of skin covered with silvery-white scales
• Itching, burning, or soreness around affected areas
• Dry or cracked skin that may bleed
• Nail pitting, ridging, or discoloration
• Joint pain or stiffness (in patients with psoriatic arthritis)

During your visit, your dermatologist will review your medical and family history, identify possible triggers, and examine your skin and nails to determine the type and severity of psoriasis. This information helps guide an individualized, long-term treatment plan.

Diagnosis

Diagnosis is typically made during a skin examination.¹ In some cases, your dermatologist may recommend:

• Skin biopsy: Confirms psoriasis and rules out similar-looking skin conditions
• Blood testing: Screens for related autoimmune or metabolic disorders
• Joint evaluation: If symptoms suggest psoriatic arthritis or tendon involvement

Treatment & Ongoing Management

The goal of treatment is to reduce inflammation, slow down excessive skin cell growth, and relieve discomfort. Depending on the severity and areas affected, your dermatologist may recommend:

• Topical treatments: Corticosteroids, vitamin D analogs, or retinoids for mild to moderate psoriasis
• Phototherapy: Controlled light treatments that calm inflammation and promote skin healing
• Systemic medications: Methotrexate, cyclosporine, or acitretin for widespread or resistant disease
• Biologic therapies: Targeted injectable treatments (e.g., TNF, IL-17, IL-23 inhibitors) that address immune system overactivity
• Lifestyle guidance: Stress management, gentle skincare, regular moisturization, and avoiding triggers such as alcohol or certain medications

Follow-Up & Outlook

Psoriasis is a lifelong condition, but modern therapies make clear or nearly clear skin achievable for most patients. Regular follow-up ensures optimal control, helps track response to biologic or systemic treatments, and monitors for associated joint or heart-related complications. With expert care and consistent management, patients can live comfortably and confidently.
