The role of lasers in connective tissue and inflammatory dermatoses: A 10-year retrospective review of 60 patients in a UK tertiary laser clinic
Abstract
Introduction: The role of lasers in the treatment of standard therapy-resistant inflammatory dermatoses and connective tissue disorders has been controversial and evidence supporting the role of lasers in this setting is scarce. Objective: To assess the efficacy of lasers in the management of inflammatory dermatoses and connective tissue disorders (CTD). Materials and Methods: A retrospective case review of all inflammatory dermatoses/connective tissue diseases treated in a tertiary laser clinic between March 2010 and 2020 was undertaken. Results: A total of 60 cases (48 = female) were included and the average age was 51 years (range 21 to 74). The following conditions were treated: scleroderma n = 22 (37%), granuloma faciale n = 10 (17%), sarcoidosis n = 8 (13%), discoid lupus erythematosus n = 7 (12%), and systemic lupus erythematosus n = 2 (3%). Other diagnoses included necrobiosis lipoidica, pyoderma vegetans, hypertrophic lichen planus, and dermatomyositis. The most common type of laser used was pulsed dye laser (PDL) in n = 41 (68%) cases. Eight (13%) patients received treatment with the carbon dioxide (CO2) laser. The most common site treated was the face. A good response with a marked reduction of signs was seen in 62% of patients while 10% of the patients did not respond to laser treatment. Self-limiting complications included purpura and hyperpigmentation. Limitations: Lack of objective assessment and outcome measures. Conclusions: This is the largest cohort of patients to have undergone laser treatment for inflammatory dermatoses/connective tissue disease. Based on this retrospective review, we conclude that lasers can be a useful adjunct in the management of otherwise difficult-to-treat selected inflammatory and connective tissue diseases.
