We describe the dermoscopic features of thumbnail dystrophy in 3 women (age range, 49-54 years) with Hailey-Hailey disease, including 2 sisters (Figures 1, 2, and 3). All patients presented with typical flexural crusted erosions with acantholysis on skin biopsy but without features suggestive of Darier-White disease. Fingernail involvement was asymptomatic and mainly affected the thumbs.
