Abstract
Acrodermatitis continua of Hallopeau (ACH) is a rare, sterile pustular psoriasis variant refractory to many conventional treatments. The eruption typically occurs after local trauma or infection; other etiologies include neural, inflammatory, and genetic causes. Herein, we reported a single case of a 61-year-old patient with ACH that was successfully treated with guselkumab for 76 weeks. At first, the patient was misdiagnosed with onychomycosis. Due to the worsening of nail lesions, the patient was admitted to our hospital. Subungual pustules were observed, and multiple cultures of the pustules were all negative. Thus, a diagnosis of ACH was made. The patient was treated with 100 mg guselkumab post admission. Four weeks after the first infusion, the patient showed minimal improvement; eight weeks after the second infusion, the patient showed clinical improvement and was still under treatment. Meanwhile, whole exome sequencing was performed for our patient, revealing no rare coding variant in IL36RN, CARD14, or AP1S3. This case report is associated with a review of recent data on ACH with biological treatments and gene mutations.
