Lichen nitidus, which literally means 'shiny moss,' is a relatively rare, chronic skin eruption that is characterized clinically by asymptomatic, flat-topped, sharply demarcated, skin-colored papules, which are sometimes described as [...]

Background: Pediatric psoriasis is a common, disfiguring cutaneous disease that has significant consequences on patient quality of life. The current biologic regimens for moderate to severe pediatric psoriasis vulgaris include ustekinumab, and etanercept or adalimumab. The evidence for use of other biologic agents has been limited.Objective: To provide evidence of the efficacy of ixekizumab, an IL-17 inhibitor, in the treatment of refractory pediatric psoriasis and to summarize the use of ustekinumab, etanercept, and adalimumab in pediatric moderate to severe psoriasis vulgaris.Methods: A 15-year-old male with severe, refractory psoriasis vulgaris was treated with ixekizumab injections with the following dosing: 160 mg loading dose, followed by bi-weekly 80 mg for 12 weeks, then monthly 80 mg. The PubMed database was used to search the following terms: adalimumab, etanercept, pediatric, psoriasis, refractory, resolution, treatment, and ustekinumab. The relevant randomized controlled clinical trials generated by the search were summarized.Results: Four weeks after initiating ixekizumab injections, the patient had striking improvement in his psoriatic lesions with a decrease in baseline Physician’s Global Assessment from 3 to 1 and a decrease in Psoriasis Area Severity Index from 32.1 at initiation to 2.7 at 1 month.Conclusion: Ixekizumab is not currently a Food and Drug Administration (FDA)-approved treatment for pediatric psoriasis. Ustekinumab and etanercept are both FDA approved and have been used with good, but incomplete responses in many cases. This case report illustrates the success of ixekizumab in the treatment of pediatric psoriasis refractory to traditional regimens and suggests IL-17 blockade may be highly effective in treating moderate to severe pediatric psoriasis.
