A Case of Concurrent Psoriasis and Hidradenitis Suppurativa Successfully Treated with Tildrakizumab

Plaque psoriasis and hidradenitis suppurativa are chronic inflammatory skin conditions with common pathogenetic pathways.We report the case of a 38-year-old man with 15-year history of psoriasis and hidradenitis suppurativa successfully treated with tildrakizumab for both conditions. After treatment failure to adalimumab, secukinumab, and guselkumab, tildrakizumab therapy was initiated and resulted in complete remission of psoriasis and the achievement of hidradenitis suppurativa clinical response after 40 weeks, without reporting adverse events. These responses were maintained at week 52.Tildrakizumab may be an effective and safe therapeutic option for concomitant psoriasis and hidradenitis suppurativa.
