These itchy lesions first appeared on the dorsum of her right hand at the age of 1 year, and they easily ruptured, leading to macerated or crusted erosions/plaques. Hyperor hypopigmentation was noted after the lesions healed. The lesions progressed to involve her right body generally, with a linear distribution on her right extremities. The lesions exacerbated in summer. No extracutaneous abnormalities were found. Her father and grandfather had mild and recurrent blisters and erosions distributed symmetrically at intertriginous sites, with an onset age of around 30 years. A biopsy specimen was obtained from the lesion on the abdomen.
