Rapid response of erythrodermic pityriasis rubra pilaris to tildrakizumab

Abstract

The cases of two patients with erythrodermic pityriasis rubra pilaris that showed a rapid and virtually complete response to tildrakizumab are presented. Treatment of pityriasis rubra pilaris remains challenging and there is very little evidence about use of interleukin-23 blockers in this condition. These cases may contribute to extending the available therapeutic options, especially when a fast clearance of the lesions is needed.
