Predominant telangiectatic erythema in linear atrophoderma of Moulin: novel variant or separate entity?

Linear atrophoderma of Moulin is a distinctive disease originally described in 1992 and characterized by acquired, mildly atrophic, non-sclerotic, slightly hyperpigmented lesions following the lines of Blaschko. Here, we describe a 15-year-old girl with a 13-year history and a 29-year-old male with a 6-year history of prominent linear telangiectatic erythema and mild atrophoderma following the lines of Blaschko that involved the right leg and hip, and both legs, the trunk and both arms, respectively. As pronounced telangiectatic erythema within lesions of atrophoderma of Moulin has not hitherto been described, we propose that the disease in our patients represents a novel variant of linear atrophoderma of Moulin. Due to considerable overlap, we do not favour the notion that our cases constitute an entity entirely separate from linear atrophoderma of Moulin.
