Lichen amyloidosis successfully treated with fractional ablative laser CO₂: A new alternative therapeutic

ABSTRACT

Lichen amyloidosis is a primary localized cutaneous amyloidosis. Different types of treatment have been used without complete resolution. Herein, we report a case of patient suffering from lichen amyloidosis successfully treated with fractional ablative laser CO₂. He was a 59-year-old man diagnosed lichen amyloidosis localized on the legs 10 years ago. He was treated with topical corticosteroids without any improvement. Then, we started treating the affected area with CO₂ laser (limmer*) at a setting of 5–8 J/cm² and 8 mm laser spot size. A considerable improvement was noticed after the first session. A total healing was reported after four sessions. To the best of our knowledge, only 11 reported cases of lichen amyloidosis have been successfully treated with laser CO₂. However, our clinical finding seems to be one of the best reported results.
