Linear cutaneous lupus erythematosus in the lines of Blaschko.

Eleven patients with linear cutaneous lupus erythematosus following the lines of Blaschko have been previously reported in the literature. We describe a child with this entity following Blaschko lines on the trunk. The patient responded to oral hydroxychloroquine therapy combined with topical flurandrenolide tape resulting in resolution with atrophic scarring. The clinical and histological features of linear cutaneous lupus erythematosus are discussed and a review of the literature is presented.
