In 2010 guidelines of care for the treatment of psoriasis with phototherapy or photochemotherapy have been published. The modalities discussed are narrowband (NB) or broadband (BB) ultraviolet B (UVB) phototherapy, alone or with topical agents such as steroids, calcipotriol or tazarotene. Co-therapy with systemic agents such as methotrexate, ciclosporin and retinoids are also discussed. UVB and psoralen/ultraviolet A (PUVA) therapy alone and with biologics such as alefacept and etanercept are discussed as are the use of excimer laser, Grenz rays and PUVA photochemotherapy with oral 8-methoxypsoralen. Trials comparing BB-UVB versus NB-UVB and NB-UVB versus oral PUVA are also included (Menter, A. et al. J Am Acad Dermatol 2010, 62(1): 114).
