Trichoscopy as a Diagnostic Tool in Trichorrhexis Invaginata and Netherton Syndrome

The study discussed the use of trichoscopy as a diagnostic tool for Netherton syndrome, a rare autosomal recessive disease characterized by erythroderma, ichthyosis linearis circumflexa, atopy, and a specific hair shaft abnormality known as trichorrhexis invaginata or bamboo hair. The case of a 4-year-old boy with these symptoms was presented, where trichoscopy successfully identified the characteristic bamboo and "golf tee" hair, confirming the diagnosis of Netherton syndrome. The study highlighted trichoscopy as a non-invasive, quick, and effective method for diagnosing hair shaft disorders, suggesting its use in children with erythroderma to aid in the accurate diagnosis of Netherton syndrome.
