Nail psoriasis is associated with significant disease burden, negative impact on quality of life, and potential progression to psoriatic arthritis. Initiating timely and appropriate treatment is of the utmost importance, especially because nail disease may be more resistant to therapies than cutaneous psoriasis.

Also reviewed are consensus treatment guideline recommendations. An updated algorithm to aid physicians in selection of specific treatment options is provided.
