When a newborn infant is exposed to low environmental temperatures, an evanescent, lacy, reticulated red and/or blue cutaneous vascular pattern appears over most of the body surface. This vascular change represents an accentuated physiologic vasomotor response that disappears with increasing age, although it is sometimes discernible even in older children.
Persistent and pronounced<unk>  occurs in Menkes disease, familial dysautonomia, cornelia de Lange, trisomy 13 and trisomy 18 syndromes.<unk>  telangiectatica congenita is clinically similar, but the lesions are more intense, may be segmental, are persistent, and may be associated with loss of dermal tissue, epidermal atrophy and ulceration.
