Blaschkoid lichen planus: Not a Koebner phenomenon.

Linear lichen planus (LP) is commonly seen as an effect of the koebner phenomenon and can occur in any site. However, LP in a whorl pattern along Blaschko lines is rarely mentioned in the literature. We highlight this rare form in a 32-year-old female with multiple hyperpigmented lesions with various patterns along the lines of Blaschko on the left side of the trunk. The clinical and histological findings were suggestive of LP.
