Key Takeaways
- Face/neck first-line: topical calcineurin inhibitors (tacrolimus 0.03–0.1%) are preferred to avoid steroid atrophy.
- Generalized disease: NB-UVB 311 nm 2–3×/wk with pediatric dose moderation; use excimer 308 nm for focal rims or small patches.
- Safety: goggles, shielding, incremental dosing, and emollients reduce AEs; steroid pulses off-face with breaks.
- Family workflow: brief visits, photo checklists, and simple home routines improve adherence and outcomes.
Diagnosis Nuances in Children
- Confirm with Wood’s lamp (chalk/blue-white accentuation) and dermoscopy (perifollicular islands).
- Common mimickers: pityriasis alba, post-inflammatory hypopigmentation, tinea versicolor—check for fine scale and consider KOH if needed.
- Baseline photos + F-/T-VASI; consider simple QoL screen for the child/parents.
Topical Therapy (First-Line)
| Site | Preferred agent | Frequency | Notes |
|---|---|---|---|
| Face/neck & folds | Tacrolimus 0.03–0.1% | Once nightly (up to BID) | Start low to reduce stinging; emollient first if sensitive |
| Trunk/limbs (small areas) | Tacrolimus or mild steroid | Nightly; steroid in pulses | Alternate with tacrolimus to minimize atrophy |
| Acral patches | Tacrolimus | Nightly | Combine with excimer for rims |
NB-UVB 311 nm: Pediatric Protocol
- Frequency: 2–3×/wk on non-consecutive days.
- Start dose: lower end of device/phototype tables; escalate by 10% if no erythema >24 h.
- Protection: child-sized goggles; cover uninvolved skin; moisturize after sessions.
- Course: 24–36 sessions then reassess; continue if responding; taper to weekly → q2wk for maintenance.
- Spacing with topicals: apply tacrolimus on off-light days or ≥8–12 h apart.
Excimer 308 nm: When to Use
- Ideal for periorificial face, small focal macules, and rims that lag on NB-UVB.
- Schedule 2–3×/wk mini-cycles (e.g., 6–12 weeks) with quick reviews to keep children engaged.
- Pair with tacrolimus between light days.
Where Steroids Fit (Off-Face)
- For short pulses on trunk/limbs if plateauing: low-to-mid potency 1–2×/day for 1–2 weeks, then break.
- Avoid chronic daily use; monitor for atrophy and striae; prefer tacrolimus for long-term control.
Adherence, QoL & School Considerations
- Create a simple weekly plan (stickers/check boxes). Celebrate milestones (first islands!).
- Provide a short script for parents/teachers to reduce stigma and explain treatment days.
- Consider child-appropriate QoL tools and camouflage options for events/photos if desired.
Follow-up & Maintenance
- Review at 8–12 weeks for early response; optimize regimen and friction/sun care.
- After fill-in, transition to proactive tacrolimus 2–3 nights/week on face/neck; taper NB-UVB.
- Plan early “rescue” slots for rims with excimer 308 nm to avoid relapse spread.
