Chronic hand eczema unresponsive to topical steroids: a judgement call on escalation
A 42-year-old hairdresser has a 4-year history of hand dermatitis, worse on the fingers and web spaces, with fissuring and scaling. She has tried multiple topical steroids (including clobetasol under occlusion) and emollients with partial, temporary benefit. Patch testing to a standard series was negative 2 years ago. She now has thickened, lichenified plaques and reports significant impact on work and sleep. She is keen to avoid systemic steroids because of weight gain. She has no other medical history and takes no regular medication.
1. What is your diagnostic and management approach, and what would you do differently from her previous care?

Reassess the diagnosis and exposures: chronic hand eczema in a hairdresser is likely occupational irritant and/or allergic contact dermatitis, with possible atopic background. A negative standard series 2 years ago does not exclude relevant allergens (e.g., hair dyes, preservatives, fragrances, acrylates, nickel, rubber chemicals). Repeat/extended patch testing with an occupational series and her own products is warranted. Take a detailed occupational history (gloves, wet work, products, frequency of hand washing).
Optimize topical therapy: ensure adequate potency and duration, correct application, and treatment of any secondary infection. Consider a short course of potent topical steroid under occlusion (already tried) or topical calcineurin inhibitor for steroid-sparing maintenance. Emollients and barrier creams should be used liberally, especially before work.
Non-pharmacologic: reduce wet work, use appropriate gloves (cotton liners under nitrile; avoid latex if sensitized), and workplace modifications. Refer to occupational health if available.
Escalation options: if adequate topical therapy fails, consider phototherapy (PUVA or narrowband UVB) for chronic hand eczema, or systemic therapy (e.g., methotrexate, ciclosporin, or newer agents such as dupilumab if atopic phenotype) after appropriate workup. Avoid systemic steroids given her preference and risks.
2. She asks about long-term prognosis and work. How would you counsel her, and what follow-up would you arrange?

Counseling:
- Chronic hand eczema is often relapsing and occupational; without exposure control, it is likely to persist. Explain the role of wet work, irritants, and potential allergens, and that identifying and avoiding triggers is as important as medication.
- Discuss that topical therapy controls flares but does not cure; maintenance therapy and emollients are needed.
- Discuss the impact on work: hairdressing involves wet work and chemical exposure; recommend gloves, barrier creams, and workplace adjustments. If symptoms are unmanageable, occupational health input and consideration of redeployment may be needed.
- Explain escalation options and their monitoring requirements (e.g., methotrexate: FBC, LFTs, renal function; ciclosporin: BP, renal function).
Follow-up: review in 4-6 weeks after optimizing topical therapy and repeat patch testing; assess response, adherence, and occupational modifications. If no improvement, initiate phototherapy or systemic therapy with appropriate baseline investigations and monitoring. Document the discussion and provide written information.
