Pulsed Dye Laser for the Treatment of Nail Psoriasis

Psoriasis can involve the skin, joints, and nails, either alone or in combination. Psoriasis of the nails can involve both the nail bed and nail matrix. The treatment of nail psoriasis largely depends on the severity of symptoms. The pulsed dye laser (PDL) recently has demonstrated efficacy in treating resistant plaque-type psoriasis and has been suggested as an alternative to conventional therapies. We review 4 studies of PDL for nail psoriasis and discuss the findings in relation to treatment recommendations. Ultimately, a standardized regimen for the treatment of nail psoriasis remains elusive.
