Pigmented linear discoid lupus erythematosus following the lines of Blaschko: A retrospective study of a Chinese series

Conclusion: Pigmented linear discoid lupus erythematosus mostly occurs on the head and neck. It manifests as brownish macules along the lines of Blaschko. Differentiation between pigmented linear discoid lupus erythematosus and other dermatoses that have a linear distribution can be difficult both clinically and pathologically, but histological details can help distinguish them.
