Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder characterized by numerous lentigines grouped within an area of normal skin. Although treatment is not necessary, many patients with facial PUL seek medical help for cosmetic reasons. There is no established standard treatment for PUL. Conventional lasers may cause postinflammatory hyperpigmentation because keratinocytes are injured during the process. Also, scarring, long downtime, and pain are important issues. A 19-year-old patient with facial PUL was successfully treated with low-fluence 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:YAG) laser. Although the exact mechanism by which low-fluence 1,064-nm QS Nd:YAG laser improves pigmentary lesions is unclear, the terms “subcellular selective photothermolysis” and “melanocyte apoptosis and replacement” have been proposed. If appropriate measures are taken to monitor patient response during and after the procedure, low-fluence 1,064-nm QS Nd:YAG laser may achieve good cosmetic results in the treatment of PUL with a very safe and effective profile.

Background Nepalese population with Fitzpatrick skin types III-V has high prevalence of pigmentary disorders and it is a growing cosmetic concern. Q-Switched Neodymium- Doped Yttrium Aluminum Garnet (QS Nd-YAG) laser is an efficacious tool in the treatment of pigment disorders. Objective To highlight the efficacy and safety profile of various pigment disorders. Methods A prospective study done in Dhulikhel Hospital, Kathmandu University Hospital from January 2009 to January 2011. Patients undergoing laser for pigmented skin lesions were followed for response and safety profile. We included total 270 patients in the study with various disorders especially nevus, tattoos and melasma. Settings were repeated at 3-4 weeks interval and response was evaluated on clinical basis. Efficacy was then evaluated according to various parameters. Results For nevus, total 840 treatment sessions had been performed with an average of 6.88 sessions (range 3-11). Nd: YAG laser was very efficacious in removal of blue and black colored tattoos with an average of 7.9 and 9.5 sessions respectively. However, red mixed with blue and or green tattoos were relatively resistant to treatment and required average 10.33 treatment sessions. Melasma and freckles both responded to the therapy but recurrence rate was high. Conclusion Our results indicate that QS Nd: YAG laser is an effective modality for pigment disorders among Nepalese population. Nevus and melasma respond well but recurrence rate of melasma is high. Blue tattoos respond well while mixed colored tattoos are quite resistant to Nd: YAG laser alone. Transient pain and temporary hyperpigmentation are common side effects.
