Clinical evaluation of atopic hand-foot dermatitis.
Clinical manifestations of atopic hand-foot (H-F) dermatitis have not been well studied. This study examined 108 atopic dermatitis (AD) patients with H-F dermatitis between May 1997 and July 1999 at our AD clinic to determine the clinical characteristics of atopic H-F dermatitis and to assess its etiologic associations. It usually began in childhood with an early onset of AD. Pruritus was the most frequent symptom, and erythema, scales, lichenification, hyperkeratosis, fissures, and keratolysis exfoliativa were also common signs. Both the hands and feet were involved in 47 (44.0%) patients, and either hand or foot involvement was observed in 15 (13.9%) and 46 (42.6%) patients, respectively. Palmar or plantar surfaces were more frequently involved than the dorsal aspects. The great toe was affected more often than the other toes. Two-thirds of patients presented with manifestations of the ichthyosis triad and sandpaper-like skin lesions on the elbow, knee, and lateral malleolus. Palmar or plantar hyperhidrosis was reported in 15% and 20%, respectively. The ichthyosis triad-associated group showed a significantly higher incidence of sandpaper-like (thickened, roughened) skin lesions, and these patients had lesions on the dorsal hands or heels and lateral malleolus more frequently than ichthyosis triad-absent patients. The hyperhidrosis-associated group showed an association with glassy lesions, localized to palmar or plantar areas. Atopic H-F dermatitis is associated with the nonallergic etiologies of AD and clinical subgroups can be identified on the basis of nonallergic backgrounds.
