Psoriasis

Psoriasis is a chronic, immune-mediated, systemic inflammatory disease primarily characterized by the hyperproliferation of keratinocytes. It manifests as well-circumscribed, erythematous plaques covered with silvery scales. While predominantly cutaneous, it is recognized as a systemic condition associated with comorbidities including cardiovascular disease and metabolic syndrome.

Psoriasis is polygenic, with a strong association with the HLA-Cw6 allele. Environmental triggers include infections (e.g., Streptococcal), physical trauma (Koebner phenomenon), stress, smoking, alcohol, and certain medications like beta-blockers or lithium.

The disease involves a complex interplay between the innate and adaptive immune systems. T-helper 17 (Th17) cells secrete IL-17 and IL-23, signaling keratinocytes to undergo rapid, aberrant turnover (3–5 days vs. the normal 28–30 days), resulting in parakeratosis and acanthosis.

Psoriasis affects 2–3% of the global population. It typically presents in two peaks: late adolescence (15–20) and mid-adulthood (55–60). There is no significant gender bias.

Genetic predisposition, obesity, metabolic syndrome, psychological stress, tobacco use, and chronic infections.

A. Early Symptoms

• Small, red, scaly papules (guttate appearance).


• Itching (pruritus) in localized areas. B. Common Symptoms


• Thick, raised erythematous plaques.


• Silvery-white scales.


• Dry, cracked skin that may bleed.


• Nail pitting and oil spots. C. Advanced Symptoms


• Extensive body coverage (erythrodermic).


• Joint pain and swelling (psoriatic arthritis).


• Severe inflammation of intertriginous zones. D. Emergency Symptoms


• Generalized pustular lesions (von Zumbusch).


• Widespread skin shedding with systemic fever (erythrodermic psoriasis).

• Auspitz sign: Pinpoint bleeding when scales are removed.
• Koebner phenomenon: Lesions appearing at sites of skin trauma.
• Thickened, "sausage-like" digits (dactylitis).

A. Clinical Assessment: History and visual inspection.
B. Laboratory Testing: Usually for ruling out mimics or monitoring biologics.
C. Imaging Studies: X-rays for psoriatic arthritis.
D. Functional Tests: PASI score for severity.
E. Biopsy Findings: Parakeratosis, acanthosis, and Munro’s microabscesses.
F. Genetic Testing: Generally not required for diagnosis.
G. Differential Diagnosis: Eczema, seborrheic dermatitis, tinea.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Evaluate systemic inflammation
Expected Findings: Mild leukocytosis
Interpretation: Indicates active inflammatory burden

X-ray (Joints)
Purpose: Screen for PsA
Typical Findings: Marginal erosions and "pencil-in-cup" deformities.

• Atopic dermatitis (lack of silver scales).
• Lichen planus (purple, polygonal papules).
• Tinea corporis (peripheral clearing).

Psoriatic arthritis, cardiovascular disease, depression, metabolic syndrome, and ocular inflammation (uveitis).

A. Lifestyle Modifications: Weight loss, smoking cessation, stress management.
B. Preventive Measures: Avoidance of triggers (Koebner trauma).
C. Medical Treatment: Topical corticosteroids, vitamin D analogues, phototherapy (UVB), Methotrexate, TNF-inhibitors (Adalimumab).
D. Surgical Treatment: Rarely, joint reconstruction for severe arthritis.
E. Interventional Procedures: Excimer laser.
F. Rehabilitation: Physical therapy for arthritis.
G. Emergency Management: Hospitalization for fluid management in erythrodermic psoriasis.

Chronic condition; periods of remission and exacerbation. Not curable but highly manageable.

Screening for comorbidities; early therapeutic intervention to limit disease activity.
