Psoriasis 4
Epidemiology Common skin disorder Prevalence variable: ~ 0.3–2.5% Prevalence equal in males and females Estimated incidence: ~ 60 per 100,000 per year 5
Age of onset Mean age: ~ 23–37 years Current theory: 2 distinct peaks with possible genetic associations Early onset (16–22 years) More severe and extensive More likely to have affected first-degree family member Late onset (57–60 years) Milder form Affected first-degree family members nearly absent 6
Psoriasis is a T-cell mediated, autoimmune disease 1 Current hypothesis: Unknown skin antigens stimulate immune response Antigen-specific memory T-cells are primary mediators Leads to impaired differentiation and hyperproliferation of keratinocytes 7
Clinical presentation: classic psoriasis Well-defined and sharply demarcated Round/oval-shaped lesions Usually symmetrical Erythematous, raised plaques Covered by white, silvery scales 10
Common sites affected by psoriasis Can affect any part of the body – typically scalp, elbow, knees and sacrum Extent of disease varies 1 11
Psychosocial Impact 12
Types of psoriasis Chronic plaque Guttate Flexural Erythrodermic Pustular Localised and generalised Local forms Palmoplantar Scalp Nail (psoriatic onychodystrophy) 13
Chronic plaque psoriasis Most common type – affects approximately 85% Features pink, well-defined plaques with silvery scale Lesions may be single or numerous Plaques may involve large areas of skin Classically affects elbows, knees, buttocks and scalp 14
Chronic plaque psoriasis 15

Chronic plaque psoriasis 18
Guttate psoriasis Numerous and small lesions – ~ 1 cm diameter Pink with less scale than plaque psoriasis Commonly found on trunk and proximal limbs Typically seen in individuals < 30 years Often preceded by an upper respiratory tract streptococcal infection 1. 19
Flexural psoriasis Lesions in skin folds articularly groin, gluteal cleft, axillae and submammary regions Often minimal or absent scaling May cause diagnostic difficulty when genital or perianal region is affected in isolation 1 20
Erythrodermic psoriasis Generalised erythema covering entire skin surface May evolve slowly from chronic plaque psoriasis or appear as eruptive phenomenon Patients may become febrile, hypo/hyperthermic and dehydrated Complications include cardiac failure, infections, malabsorption and anaemia Relatively uncommon 21
Pustular psoriasis Two forms: Localised form More common Presents as deep-seated lesions with multiple small pustules on palms and soles Generalised form Uncommo Associated with fever and widespread pustules across the body inflamed body surface 22
Palmoplantar psoriasis Can be hyperkeratotic or pustular May mimic dermatitis – look for psoriatic manifestations elsewhere to aid diagnosis Possibly aggravated by trauma 23
Scalp psoriasis Varies from minor scaling with erythema to thick hyperkeratotic plaques May extend beyond hairline Patient scratching may produce asymmetric plaques 24
Nail psoriasis May be present in patients with any type of psoriasis Can take several forms : Pitting: discrete, well-circumscribed depressions on nail surface Subungual hyperkeratosis: silvery white crusting under free edge of nail with some thickening of nail plate Onycholysis: nail separates from nail bed at free edge ‘Oil-drop sign’: pink/red colour change on nail surface 25
Nail psoriasis 26
Psoriatic arthritis Approximately 5–20% have associated arthritis Five major patterns of psoriatic arthritis : Distal interphalangeal involvement Symmetrical polyarthritis Psoriatic spondylarthropathy Arthritis mutilans Oligoarticular, asymmetrical arthritis Clinical expressions often overlap 27
Diagnosing psoriasis Other dermatological disorders can resemble psoriasis Diagnosed clinically according to appearance, distribution, history of lesions and family history Important to consider non-cutaneous complications 28
Managing psoriasis Goals of management Tailor management to individual and address both medical and psychological aspects Improve quality of life Achieve long-term remission and disease control Minimise drug toxicity Evaluate and monitor efficacy and suitability of individual treatments Remain flexible and respond to changing needs 31
