Netherton syndrome is characterized by scaly skin, abnormal hair, and increased risk of atopy. Scale can assume a characteristic pattern called ichthyosis linearis circumflexa, which manifests as migratory, erythematous plaques with double-edged scale at the periphery. Examination of the hair frequently reveals trichorrhexis invaginata, which is visible using light microscopy as a bamboo-like configuration in which the distal hair shaft invaginates into the proximal one. Patients experience manifestations of the atopic triad including atopic dermatitis, food allergy, and asthma and often have marked elevation of serum immunoglobulin E (IgE). Itching can be severe.
