Successful treatment of refractory prurigo nodularis with abrocitinib

Abstract

Prurigo nodularis is frequently difficult to manage with conventional therapy. Given the pathogenesis and refractory nature, we demonstrate a case in which inhibition of JAK–STAT signaling may significantly improve prurigo nodularis. Based on the results, we would like to draw a conclusion that abrocitinib as an inhibitor of Jak is a promising choice for the treatment of prurigo nodularis.
