ACH: acrodermatitis continua of Hallopeau APP: annular pustular psoriasis DLQI: Dermatology Life Quality Index GPP: generalized pustular psoriasis IL: interleukin PPP: palmoplantar pustulosis BSA: body surface area PPASI: Pustular Psoriasis Area and Severity Index VAS: Visual Analog Scale INTRODUCTION Pustular psoriasis is a well-known form of psoriasis, the main variants of which are acute generalized pustular psoriasis (GPP), including GPP of pregnancy, annular pustular psoriasis (APP), acrodermatitis continua ofHallopeau (ACH), andpalmoplantar pustulosis (PPP). APP is a rare entity that presents as recurring annular or figurate erythematous plaques with peripheral pustules and scales that expand centrifugally. Secukinumab is a novel human monoclonal antibody that inhibits interleukin (IL)-17A. Secukinumab was recently approved for the treatment of moderateto-severe plaque psoriasis and psoriatic arthritis. We present the first report to our knowledge of an APP case successfully treated with secukinumab.
