Extended Hailey-Hailey disease: Clinico-dermoscopic confrontation

Abstract

Hailey-Hailey disease is an uncommon acantholytic genodermatosis. The extensive form is unusual and poses a difficulty of differential diagnosis with other bullous dermatoses and especially those with an annular arrangement like the case of our patient, in whom the clinical presentation was atypical but the dermoscopic examination had shown usual signs of Hailey-Hailey disease. Hence the interest of our case report.
