The short answer
What matters most
- The location, appearance, itch, flare pattern, nail or joint symptoms and treatment response help distinguish the pathway.
- How a topical treatment is applied can matter as much as which product was supplied.
- Infection, major quality-of-life impact, uncertainty and poor control can all lower the threshold for escalation.
Begin with pattern, not a product
Atopic eczema is an itchy inflammatory condition that often fluctuates. Psoriasis commonly creates well-defined areas of scale and can also affect the scalp, nails and joints. Real presentations vary across body sites and skin tones, so the consultation should avoid diagnosing from one isolated feature.
Bring the treatment history
- Names or photographs of emollients and topical medicines.
- Which body sites each product was used on.
- How much and how often it was applied.
- How long it was used before deciding it had failed.
- Side effects, stinging, allergy concerns or reasons treatment was difficult to follow.
Look beyond the visible area
Sleep loss, work, school, clothing, confidence and mental health are clinically relevant. For psoriasis, recurring pain, stiffness or swelling in joints should be raised because psoriatic arthritis needs assessment.
Recognise infection and severe disease
Pain, warmth, pus, rapid worsening, fever or feeling unwell can indicate infected eczema or another complication. Rapid widespread psoriasis with systemic illness is not suitable for routine review.
When dermatology referral is considered
Referral can be appropriate when the diagnosis is uncertain, the disease is severe or extensive, appropriate topical treatment has not controlled it, recurrent infection complicates care or physical and psychological impact is substantial.
Common questions
Frequently asked
Can eczema and psoriasis be cured?
They are long-term conditions that can often be controlled, but no consultation should promise a permanent cure.
Are eczema and psoriasis contagious?
No. Neither atopic eczema nor psoriasis is contagious.
Should I stop treatment before a consultation?
Do not stop prescribed treatment unless advised. Bring details of what you use and, if the rash changes, photographs of earlier stages.
