Erythroderma in two patients with psoriasis upon discontinuation of efalizumab treatment.

Efalizumab is therapeutically effective in moderate to severe plaque psoriasis. Rebound after discontinuing therapy affects approximately 14% of patients, while erythroderma occurs in less than 1% of the treated population. In this case report, we describe two non-responding patients with severe plaque psoriasis who developed erythroderma after treatment was ceased. Non-responders are more likely to suffer from rebound. This article emphasizes the importance of close monitoring of non-responders to efalizumab after discontinuance of treatment.
