What is Psoriasis?


Psoriasis is a chronic, non-contagious skin condition characterized by the rapid buildup of skin cells, leading to scaling, redness, and inflammation. This accelerated skin cell turnover results in thick, silvery patches, often accompanied by itching and discomfort. Psoriasis can affect any part of the body, including the scalp, elbows, knees, and nails, and may vary in severity from mild irritation to extensive skin involvement.

Psoriasis is more than just a skin disorder; it is an immune-mediated disease linked to systemic inflammation. Globally, it affects around 2–3% of the population, making it a significant health concern. The disease can impact both physical and emotional well-being, as visible skin lesions often cause social stigma, stress, and reduced quality of life.

THANC Hospital Chennai specializes in managing psoriasis through a combination of advanced dermatologic care, personalized treatment plans, and multidisciplinary support. The hospital employs state-of-the-art diagnostic tools and the latest therapeutic options to help patients achieve effective long-term control of their condition.

THANC Hospital’s Anesthesia & Critical Care and Head & Neck Surgery and Oncology teams collaborate closely with dermatologists to ensure safe and effective treatment for complex psoriasis cases.

Understanding Psoriasis

Psoriasis arises from immune system dysfunction, which triggers an overproduction of skin cells and inflammation. It is considered a chronic autoimmune condition, often associated with genetic predisposition.

Types of Psoriasis

Psoriasis presents in multiple forms, each with distinct features:

  • Plaque Psoriasis: The most common type, characterized by raised, red patches covered with silvery scales.
  • Guttate Psoriasis: Small, drop-shaped lesions, often triggered by infections like streptococcus.
  • Inverse Psoriasis: Red, shiny patches in skin folds, including under the breasts, armpits, or groin.
  • Pustular Psoriasis: White pustules surrounded by red skin, usually localized on the hands or feet.
  • Erythrodermic Psoriasis: Rare, severe form causing widespread redness, scaling, and systemic symptoms like fever.
  • Nail Psoriasis: Affects fingernails or toenails, leading to pitting, discoloration, or detachment.

Causes of Psoriasis

While the precise cause is multifactorial, psoriasis primarily results from immune system dysregulation, which accelerates skin cell turnover. Common contributing factors include:

  • Genetic Predisposition: Family history increases susceptibility.
  • Immune System Dysfunction: Overactive T-cells trigger inflammation and skin proliferation.
  • Environmental Triggers: Stress, infections, trauma to the skin, and certain medications.
  • Lifestyle Factors: Smoking, alcohol consumption, obesity, and sedentary lifestyle may exacerbate symptoms.

Risk Factors

Several factors increase the likelihood of developing psoriasis or worsening existing lesions:

  • Age: Most commonly appears between 15–35 years, though it can develop at any age.
  • Family history of psoriasis or autoimmune diseases.
  • Obesity and metabolic syndrome.
  • Chronic stress or psychological disorders.
  • Smoking and heavy alcohol use.
  • Certain medications, including beta-blockers, lithium, or anti-malarials.

Who is Affected?

Psoriasis affects both men and women equally, though certain subtypes may appear more frequently in one gender. The condition can occur in children, adolescents, or adults, and it is a lifelong disease that may have periods of flare-ups and remission.

Common Symptoms of Psoriasis

Symptoms vary depending on the type and severity of psoriasis. Recognizing early signs is crucial for timely treatment.

Key Symptoms

  • Red, raised patches covered with silvery-white scales
  • Itching, burning, or stinging sensations on affected areas
  • Dry, cracked skin that may bleed
  • Thickened or pitted nails in nail psoriasis
  • Pain or stiffness in joints in cases associated with psoriatic arthritis
  • Small drop-like lesions in guttate psoriasis
  • Red, inflamed patches in skin folds for inverse psoriasis

When to Seek Medical Help

Immediate consultation is recommended if you experience:

  • Rapid spread of skin lesions
  • Severe itching or pain affecting daily life
  • Signs of infection, such as oozing or pus-filled lesions
  • Joint pain or swelling suggesting psoriatic arthritis
  • Emotional distress due to visible skin lesions

Early evaluation ensures accurate diagnosis and helps prevent complications, including joint damage, cardiovascular risk, and psychological impact.

Diagnosis of Psoriasis

Diagnosis is primarily clinical, supported by a detailed history, physical examination, and, when needed, specialized investigations.

Diagnostic Tools

  1. Physical Examination:
     Evaluates the size, shape, location, and pattern of lesions.
  2. Medical History:
     Includes family history, triggers, previous treatments, and comorbidities.
  3. Skin Biopsy:
     Performed in uncertain cases to confirm diagnosis and rule out other skin conditions.
  4. Laboratory Tests:
     May assess inflammation markers, rule out infections, and evaluate systemic involvement.
  5. Imaging Studies:
     X-rays or MRI may be ordered if joint involvement is suspected, particularly in psoriatic arthritis.

THANC Hospital Chennai employs high-resolution dermatologic imaging and laboratory diagnostics to provide precise assessment and individualized treatment planning. The hospital’s multidisciplinary team ensures that both cutaneous and systemic aspects of psoriasis are managed efficiently.

Treatment Options for Psoriasis

Treatment is tailored according to psoriasis type, severity, location, and patient health. The goal is to reduce inflammation, control lesions, and prevent complications while maintaining quality of life.

Non-Surgical / Medical Treatments

  1. Topical Therapies:
    • Corticosteroid creams or ointments to reduce inflammation
    • Vitamin D analogs (calcipotriol) to slow skin cell proliferation
    • Moisturizers and emollients to manage dryness and scaling
    • Coal tar or salicylic acid preparations for thickened plaques
  2. Phototherapy:
    • Controlled exposure to UVB or PUVA therapy slows abnormal skin cell growth.
    • Administered under medical supervision with precise dosing to reduce side effects.
  3. Systemic Medications:
    • Methotrexate, cyclosporine, or acitretin for moderate-to-severe cases
    • Biologics targeting specific immune pathways (e.g., TNF-alpha inhibitors, IL-17, IL-23 inhibitors)
    • Apremilast, an oral PDE4 inhibitor, for chronic plaque psoriasis
  4. Lifestyle Modifications:
    • Maintain a healthy weight to reduce inflammation
    • Avoid triggers such as smoking, alcohol, and stress
    • Balanced diet rich in antioxidants and omega-3 fatty acids
    • Adequate skin hydration and gentle cleansing routines

Surgical / Advanced Treatments

While psoriasis is primarily treated medically, advanced cases with severe plaque formation may benefit from laser therapy or excision of resistant lesions in rare situations. The hospital also integrates biologic therapy initiation and monitoring as an advanced intervention for patients with severe systemic involvement.

THANC Hospital Chennai combines advanced dermatology treatments, including phototherapy, biologics, and systemic therapy, to provide individualized care. The team works closely with rheumatologists, endocrinologists, and nutritionists for a holistic approach to patient health.

Prevention & Lifestyle Tips

Psoriasis cannot be completely prevented, but lifestyle changes can reduce flare-ups and improve overall health.

Practical Tips

  • Maintain a healthy weight to reduce systemic inflammation
  • Avoid alcohol and quit smoking to minimize triggers
  • Manage stress with meditation, yoga, or therapy
  • Follow a nutrient-rich diet with fruits, vegetables, and omega-3s
  • Keep skin moisturized and avoid harsh soaps or excessive heat
  • Limit sunburn exposure while allowing moderate sunlight for vitamin D
  • Schedule regular dermatology check-ups to monitor disease progression

Adopting these strategies helps in preventing psoriasis flare-ups, reducing disease severity, and improving long-term outcomes.
