Abstract:
Linear and whorled nevoid hypermelanosis(LWNH) is a congenital disorder which was first described by Kalter in 1988 and is characterized by asymmetrically distributed linear and whorled hyperpigmentation following Blaschko's lines. It usually appears at birth or during the first weeks of life and is rarely associated with various congenital defects. Its pathogenesis is not well known, but developmental somatic mosaicism appears the most likely cause. It is probably not a rare disease, but not well recognized or is confused with other entities. Herein, we report a typical case of LWNH in 9 month-old boy.
