Abstract
Lichen amyloidosis (LA) is a type of primary localized cutaneous amyloidosis characterized by multiple localized, hyperpigmented, grouped papules, in which the deposition of amyloid materials from altered keratinocytes usually resists to current treatments. We presented two LA patients with non-satisfactory results of topical treatments. After the first treatment using 1064-nm Nd: YAG picosecond (ps-Nd:YAG) laser, there was an improvement with persistence up to 3-month follow up after five sessions of 4-week interval, as well as a decrease in number, thickness, and darkness of lesions from clinical and dermoscopic evaluation. Thus, the ps-Nd:YAG laser could be efficacious for LA treatment.
