Abstract :

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 post-inflammatory 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 1064 nm Q-switched 1,064 nm 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 term â�?�?subcellular selective photothermolysisâ�? and â�?�?melanocyte apoptosis and replacementâ�? have been proposed. If appropriate measures are taken to monitor patient response during and after the procedure, low fluence 1064 nm QS Nd:YAG laser may achieve good cosmetic result in the treatment of PUL with a very safe and effective profile.
