Linear and Whorled Nevoid Hypermelanosis (LWNH) also known as ‘zebra-like pigmentation’ is characterized by linear and swirling streaks of hyperpigmentation along the Blaschko’s lines without preceding inflammation and atrophy. It is mainly located on trunk and limbs. The hyperpigmentation may be present at birth or may develop by early childhood.
