Background: Hidradenitis suppurativa (HS) is a debilitating skin condition whose pathogenesis is poorly understood, although interleukin (IL)-23 may play a role. IL-23 is also implicated in the pathogenesis of Crohn's disease (CD) and psoriasis, both of which can occur in patients with HS.
Case report: We present the case of a 28-year-old woman with HS, psoriasis, and CD, who was successfully treated with guselkumab after failing multiple other biologic agents.
Conclusion: Guselkumab represents a promising therapeutic option for recalcitrant HS patients with inflammatory comorbidities in which IL-23 plays a role.
Keywords: Guselkumab; IL-23; hidradenitis suppurativa.
