Dermoscopy of Congenital Hemidysplasia with Ichthyosiform Erythroderma and Limb Defects Nevus with Unilateral Limb Defects

Abstract

Here, we report the dermoscopic findings of congenital hemidysplasia with ichthyosiform erythroderma and limb defects (CHILD) nevus with left-sided ichthyosiform erythroderma and left upper-limb aplasia in a 4-month-old baby. The presence of ptychotropism and strict midline demarcation are unique features described in CHILD nevus. Dermoscopy of the CHILD nevus showed linear and dotted vessels with yellowish waxy scales on a pink background. These characteristic dermoscopic findings would also help us to differentiate it from inflammatory linear verrucous epidermal nevus.
