Localized Darier Disease When Prior Topical Therapy Has Not Achieved Remission
Clinical Scenario
This protocol addresses patients with Darier disease presenting with localized skin lesions — disease that is not disseminated or generalized — in whom a prior topical treatment line has been completed without achieving the expected outcomes.
Previous Treatment — Failure Condition
Prior line targets not met
This protocol is reached after a course of topical therapy — which may have included agents such as diclofenac sodium, tacalcitol, or tacrolimus — did not produce the expected response in the localized lesions.
Goals the previous line failed to achieve:
Marked improvement and near resolution of lesions
Remission
Next Step — Treatment Overview
For recalcitrant or resistant localized Darier disease, this protocol moves to physical and surgical modalities. Several distinct interventional approaches fall within this category — the appropriate choice depends on individual patient and lesion characteristics. The complete structured regimen is available via the link below.
Treatment goal: Resolution or marked improvement of the skin lesions.

For localized and resistant skin lesions, physical therapies including surgical excision, dermabrasion and CO2 laser ablation were the first line choices.
Electrosurgical excision was used in 2 patients who had etretinate resistant disease with good results.
Photodynamic therapy using topical 5‑amino laevulinic acid (5‑ALA) 20% was used in a case series of 6 patients with Darier disease: 2 (33%) had excellent results and 1 (16%) had no clinical improvement.
