Introduction:
Only ablative methods lead to long term remission of areas affected by Hailey-Hailey disease: excision/skin graft, cryosurgery, dermabrasion... The method using the CO2 laser is a recent addition in the management of this dermatitis. We report our experience with this technique in 4 patients.
Patients And Methods:
Carbon dioxide laser vaporization was proposed to 4 patients exhibiting Hailey-Hailey disease resistant to classical treatments. A test under local anesthesia was performed beforehand in all the patients. A 60 year-old man had an immediate reaction and refused to continue treatment. In the other 3 cases, the result of the test at 6 months was considered satisfactory. These patients were treated under general anesthesia in a single area of 50 to 70 cm2, and a half-body for comparison. The CO2 laser was used in pulse mode, with successive irradiations, until a homogenous, whitish-yellow aspect with first retraction was obtained.
Results:
Although the healing delays were long (a mean of 1 month) and required major analgesics over the first few days, the cosmetic results were satisfactory and no abnormal scarring was observed. After a median follow-up of 27 months, no relapse of the disease other than punctiform elements was noted. All the patients wanted treatment of the other remaining affected areas be continued. In 2 patients, CO2 laser vaporization permitted treatment of areas not easily accessible to other ablative methods (around the mouth, the anus and the vulva) with anatomy and normal function spared.
Discussion:
These results are globally good. Although the time to healing was long, the cosmetic and functional results were always satisfactory, without abnormal scarring. Moreover, in 2 of the patients, CO2 laser was able to treat areas inaccessible to other methods. The reason for the efficacy of ablative methods is debated. Re-epidermization with keratinocytes of appendices and not expressing the molecular defect, and the constitution of dermal cicatricial tissue, are two currently proposed hypotheses.
