Psoriasis vs Dermatitis - Comparison Table

Basis	Psoriasis	Dermatitis
Nature and definition	Psoriasis is a chronic inflammatory skin condition with well-demarcated plaques and silvery scales.	Dermatitis refers to inflammatory skin conditions like eczema or contact dermatitis, with red, itchy rashes that may blister.
Typical age of onset	Psoriasis often begins in early adulthood but can occur at any age.	Dermatitis can start in infancy or later, depending on type (atopic vs contact).
Lesion appearance	Plaques are raised, red with a silvery scale and clear margins.	Rashes are red, sometimes moist or crusty, with blistering in some types.
Common locations	Elbows, knees, scalp and lower back are typical sites.	Flexural areas (creases), hands, feet and face are common for dermatitis.
Itch intensity	Itch is variable but can be present with plaques.	Itch is often prominent, especially in atopic dermatitis.
Scalp involvement	Scalp plaques are frequently seen in psoriasis.	Scalp dermatitis is common and can cause flaky scales and irritation.
Nail changes	Nail pitting or lifting can occur in psoriasis.	Nail involvement is less characteristic but may occur with chronic eczema.
Distribution pattern	Often involves extensor surfaces in a symmetric pattern.	Distribution may follow exposure or flexural areas; patterns vary by type.
Chronicity and flares	Tends to be chronic with periodic flares.	May flare with triggers such as irritants or allergens.
Triggers and causes	Infections, stress and trauma (Koebner phenomenon) can trigger flares.	Allergens or irritants, soaps, and environmental factors commonly trigger dermatitis.
Immune mechanism	Involves Th1/Th17 pathways driving plaque formation.	Barrier dysfunction and diverse inflammatory pathways drive eczema types.
Allergic links	Psoriasis is not primarily allergy-driven.	Atopic dermatitis has strong allergic predisposition in many cases.
Infection risk	Secondary infections can occur with fissured plaques.	Barrier disruption raises infection risk in dermatitis.
Diagnosis approach	Diagnosis is usually clinical; biopsy may confirm psoriasis features.	Diagnosis relies on history, distribution, and may use patch testing or biopsy if needed.
Face involvement	Face involvement can occur but is less common.	Face involvement is common in dermatitis, particularly atopic types.
Seasonal variation	Flares may be influenced by weather and humidity.	Flares relate to humidity, allergens, or irritants depending on type.
Comorbidity associations	Can be associated with psoriatic arthritis and metabolic issues.	Linked with other allergic conditions and eczema-related comorbidities.
Family history	Genetic predisposition is often more evident in psoriasis.	Family history varies by dermatitis subtype.
Quality of life impact	Visible plaques can affect self-image and social life.	Chronic itching and persistent rashes impact daily activities.
Work/school impact	Flare-related discomfort can reduce productivity.	Care routines and symptoms may disrupt routines at work or school.
Moisture sensitivity	Dry skin can worsen plaques; moisturisers may help.	Dermatitis skin is usually sensitive to moisture and irritants; barrier repair matters.
Koebner phenomenon relevance	Trauma can precipitate new psoriasis lesions.	Dermatitis is less linked to Koebnerization.
Pigment changes after inflammation	Post-inflammatory changes can occur, especially in darker skin.	Pigment changes may follow dermatitis inflammation.
Scarring risk	Scarring is uncommon in psoriasis, though severe variants exist.	Dermatitis may scar if lesions are excoriated or infected.
Sensitivity to sun	Some psoriasis plaques improve with sunlight, others not.	Sun exposure can worsen some dermatitis types and improve others.
Distribution on joints	Lesions often appear near joints such as elbows and knees.	Dermatitis can involve joints and surrounding skin in flexures.
Scalp vs body appearance	Scalp can be involved with hairline margins.	Scalp dermatitis causes itching and flaking around the hairline.
Common misdiagnoses	Psoriasis may resemble fungal infections or eczema.	Dermatitis may resemble psoriasis or contact dermatitis.
Diagnosis time	Diagnosis is often straightforward but may be delayed in atypical cases.	Diagnosis may require history and tests to distinguish types.
Healthcare setting	Often managed by dermatologists for complex cases.	Typically first assessed in primary care with specialist referral as needed.

What is Psoriasis?

Psoriasis is a chronic inflammatory skin condition characterized by red, scaly plaques that commonly appear on elbows, knees, scalp and lower back. It results from immune-mediated skin turnover and varies in severity.

Clinically, psoriasis can vary from mild, localized plaques to widespread involvement, impacting daily activities and self-image. It may coexist with psoriatic arthritis, and people may seek dermatology care for diagnosis, monitoring, and guidance on lifestyle strategies.
