摘要

Dominant dystrophic epidermolysis bullosa pruriginosa (DDEB-pr; Online Mendelian Inheritance in Man 604129) is an unusual variant of DDEB characterized by recurrent intense pruritus and hypertrophic scarring. Several pathogenic mutations have thus far been detected within COL7A1 in DDEB. Here, we report a case of DDEB-pr with a c.7868G>A (G2623D) mutation within COL7A1. A 53-year-old man was referred to our clinic for evaluation of recurrent intense pruritus and hypertrophic scarring over both shins and elbows (Fig. 1) that had been present since the age of 12 years. He also had mild toenail dystrophy but fingernails remained normal. He had no past medical history of atopic dermatitis or any other type of dermatitis. He was single and was the only child. His mother had pruritus and hypertrophic scarring over both shins, but the lesions were milder. His grandparents did not have any past medical history of dermatitis.
