ABSTRACTLasser technology has greatly improved the ability to treat melanocytic lesions and tattoos with the rapidly pulsed Q-switched neodymium: yttrium-aluminium-garnet (Nd:YAG) lasser. The lasser treatment of pigmented lesions and tattoos are based on principle of selected photothermolysis. The QS lasser system can successfully lighten or eradicate a variety of benign epidermal and dermal pigmented lesions and tattoos with minimal risk of untoward effects, such as; senile lentigines, pigmented nevi, ephelides, café –au-lait– macules, nevi of Ota/Ito, seborrheic keratoses, blue nevi, nevus spilus, drug induced hyperpigmentation, Becker´s nevi, amateur and professional and traumatic tattoos. The objective of this paper was to review the pathology treated with this lasser at the “Clinica de Imagen Corporal Medica Sur Hospital”. We attended 186 patients in two years from February 2004 until February 2006. Sixty five (34.9%) male and 121 (65.1) female patients. The range age was from 1 to 86 years old. Fifty seven percent of the patients were in an age range from 21 and 40 years old. The diagnosis were: Tattoos in 39.7%, lentigines 34.9%, Ota nevi 5.9%. The patients received from 1 to 10 sessions of treatment with satisfactory results in 95% of the patients that completed it. The complications presented were hemorrhagic points with inflammatory reaction in 3 patients (1.6%) treated conservatory without sequela. The collateral effects were pain and redness. In 41 cases (22 %) abandoned the treatment. We present some clinical cases that represent the different lesions.
