Coloration of the skin on the face due to clofazimine is cleared by Q-switched ND-YAG laser / 나학회지

ABSTRACT

The Clofazimine is a rimino-phenazine dye. The color is a purplish-back. The drug is reported to be weakly bactericidal and also effective in the management of leprosy reactions apparently. The drug produces relatively few side effects in the majority of patients. The most prominent is coloration of the skin. The coloration can range anywhere from a reddish-tan to purplish-black. so, many patients avoid taking clofazimine. The Q-switched ND-YAG laser is a good medical instrument for clearing coloration of the skin. It releases two wavelength of 532nm and 1064nm. The wavelength of 532nm reachs shallow depth of the skin. So, it is effective in the clearance of a red, yellow tatto, freckle and lentigo. The wavelength of 1064nm reachs about 4-6mm depth of the skin. So, it is effective in the clearance of blue-black tatto and ota nevus. The leprosy patients who has purplish-black coloration of the skin in the face due to clofazimine is cleared by Q-switched ND-YAG laser. We operated twice with 3months interval. The wavelength is 532nm, spot size 3mm, energy 1.5J/cm2. The coloration of the skin in the face is almost cleared.
