Postnatal Confirmation of Prenatally Diagnosed Trisomy 20 Mosaicism in a Patient with Linear and Whorled Nevoid Hypermelanosis

1 Nov 2004

Abstract excerpt

Linear and whorled nevoid hypermelanosis (LWNH) is characterized by hyperpigmented reticulate macules in a Blaschko linear arrangement without atrophy or preceding inflammation. Underlying chromosomal mosaicism was often assumed, but has been verified in only a few published cases. We report a 7-year-old boy with LWNH associated with congenital ventricular septal defect and psychomotor retardation. Prenatal...
