Nail involvement in psoriasis is common, and the severity of it does not always parallel the intensity of cutaneous disease. We created a consensus group, of which the aim was to provide practical recommendations for the treatment of nail psoriasis in patients without skin psoriasis or with mild skin lesions with no indication for a systemic treatment. This collaborative process was conducted by an international panel of dermatologists with special expertise in nail disorders, using formal consensus methods. During this process, the panel strived to establish an agreement regarding the definition of nail psoriasis, the severity of nail psoriasis, and treatment response. Treatment recommendations are provided

There is some controversy about the prevalence of onychomycosis in patients with psoriasis compared to non-psoriatics. We therefore measured the prevalence of toenail onychomycosis in psoriatics and non-psoriatics attending dermatologists' offices. None of the patients had a referring diagnosis of onychomycosis. The prevalence of pedal onychomycosis in psoriatics (n = 561) was 13%. The odds of patients with psoriasis having onychomycosis was 56% greater than non-psoriatics of the same age and sex (P = 0.02). In the psoriatics, when the toenails were clinically abnormal, the prevalence of onychomycosis was 27%. The odds of developing onychomycosis increased with age (P < 0.0001) and the odds of men developing onychomycosis was 2.5 times that of women (P = 0.0001). The duration of psoriasis did not significantly affect the odds of developing onychomycosis. The fungal organisms recovered from psoriasis subjects with onychomycosis were similar to those in the normal population with onychomycosis (P = 0.58).
