Trichoscopy in Unveiling the Triad of Netherton Syndrome

The document discusses a case of Netherton syndrome (NS), a rare genetic disorder characterized by congenital ichthyosiform erythroderma, hair shaft abnormalities, and atopic diathesis. The case involves a 16-year-old girl with symptoms including scaly skin lesions, brittle hair, and high serum IgE levels. Trichoscopy revealed characteristic hair abnormalities such as trichorrhexis invaginata, aiding in diagnosis. Treatment with low-dose isotretinoin showed improvement in skin lesions. The report emphasizes the importance of recognizing NS, which is often misdiagnosed as atopic dermatitis, and highlights trichoscopy as a valuable diagnostic tool.
