Lichen striatus in Adult
The nomenclature of lichen striatus in adults has remained controversial. Some authors classify acquired Blaschko dermatitis as the adult form of lichen striatus. Others view it as a separate diagnosis given its distinctive histopathology as well as the fact that typical lichen striatus cases are encountered in adults.
