A pigmentary skin defect is a new finding in Marshall-Smith syndrome.

Marshall-Smith Syndrome (OMIM 602535) was described initially by Marshall in two infants with a syndrome characterized by accelerated skeletal maturation, failure to thrive, and dysmorphic facial features. We report a new patient with clinical features of Marshall-Smith syndrome with additional findings such as hyperpigmented lines on trunk and the four extremities. © 2011 Wiley-Liss, Inc.
