Successful Treatment of Pityriasis Rubra Pilaris with Ixekizumab

Abstract

Pityriasis rubra pilaris is an inflammatory dermatologic disorder of unknown cause and often confounded with psoriasis. It is characterised by hyperkeratotic follicular papules, scaly erythematous plaques, palmoplantar keratoderma, and a progression to generalised erythroderma. Here, we report the case of a 68-year-old man with pityriasis rubra pilaris, who was successfully treated with ixekizumab, an interleukin-17A inhibitor.
