A late presentation of Hailey–Hailey disease with clinical-dermoscopic-histological correlation

Abstract

Sir, Hailey–Hailey disease (HHD) is a blistering disease caused by mutation in ATP2C1 gene with autosomal dominant inheritance. The usual age of presentation is late teenage or in adulthood (30s and 40s).[1] Delayed diagnosis is common, especially if the patient’s lesions respond to topical steroids and antifungals.[1] We present a clinically misdiagnosed case in an elderly female and attempt a clinic-dermoscopic-histological correlation.
