Netherton's syndrome: an electronmicroscopic study.

An ultrastructural study of 2 patients with Netherton's syndrome (bamboo hair, scaling dermatosis, and an atopic diathesis) showed features of psoriasis and a dermatitis. Although the biopsies from the patients showed histological and ultrastructural similarities, the clinical presentations were different. One patient had ichthyosis linearis circumflexa, while the other had a generalized ichthyosiform eruption. The ultrastructural findings in the 2 patients, while not specific, may help distinguish the eruption of Netherton's syndrome from other scaling dermatoses.
