[Apremilast in the treatment of palmoplantar pustulosis : A case series]

This is a case series of 8 patients with palmoplantar pustulosis. These patients were treated with the phosphodiesterase‑4 inhibitor apremilast at our psoriasis outpatient clinic at the dermatological department of the University Hospital Innsbruck and we compared and documented the clinical response using an Investigator's Global Assessment (IGA) score over several months. This disease is characterized by its strong negative impact on the quality of life in affected patients, and by its resistance to therapy and its high relapse rate. Therapy options are relatively rare or off label. Apremilast is a safe and effective therapeutic approach in palmoplantar pustulosis.
