Hyperlinear palms: association with ichthyosis and atopic dermatitis

Abstract

The skin and palmar markings were examined in 178 patients with atopic dermatitis, 66 (37%) of whom had ichthyosis vulgaris. Increased palmar markings were found in 49 (28%) patients, while a normal pattern of palmar markings was present in 129 (72%) patients. Increased palmar markings were commonly observed in patients with atopic dermatitis and ichthyosis, while normal palms were found in almost all patients with atopic dermatitis alone. It is suggested that the increased palmar markings often seen in patients with atopic dermatitis are actually a manifestation of concomitant ichthyosis vulgaris.
