Carbon dioxide laser for the treatment of lupoid cutaneous leishmaniasis (LCL): a case series of 24 patients.

We report the use of a carbon dioxide laser to vaporize local cutaneous leishmaniasis. We used CO2 laser for the treatment of 24 patients with lupoid cutaneous leishmaniasis in Isfahan. We identified 24 patients with lupoid cutaneous leishmaniasis (LCL) for evaluation. All of the patients had clinical signs of LCL and had the lesion for more than 1 year. LCL diagnosis was confirmed by both direct smear and biopsy. The efficacy of laser was determined on the basis of cure and lack of relapse after 1 year. Treatment was performed using a CO2 laser (Lasersonic LS500 machine). The maximum power was 100 Watts and the pulse width was 0.5-5 seconds. There were 21 patients, 13 females and 8 males, who were treated and followed for 1 year. Mean duration of the lesions was 4.1+/- 3.9 years. The treatment was well tolerated and complications were minimal, and included pain, xerosis, and mild erythema. Of these patients, 19 were disease free (90.47 % efficacy based on clinic and laboratory). Only 2 patients were treatment failures (9.5 %). Our results indicate that CO2 laser radiation is highly effective for treatment of lupoid cutaneous leishmaniasis.
