Two cases of eosinophilic pustular folliculitis successfully treated with abrocitinib

Abstract

AbstractEosinophilic pustular folliculitis (EPF) is a rare, non‐infectious, inflammatory disease characterized by an eosinophil‐dominated infiltrate within and around pilosebaceous units. Sometimes, EPF manifests with eruptions in follicle‐free areas, although it is not common, and treatment may be difficult. In this case study we report two patients with refractory EPF who presented with eruptions of both classic follicle areas and follicle‐free areas. These two patients were successfully treated with abrocitinib after treatment failure with several traditional therapies, such as indomethacin, steroids, and cyclosporin. One patient achieved complete remission at week 4 and the other at week 1, with no reported adverse effects. Therefore, we believe that abrocitinib may be a viable and safe therapeutic option for refractory EPF.
