Trichoscopy as a Diagnostic Tool in Trichorrhexis Invaginata and Netherton Syndrome

Netherton syndrome, a rare autosomal recessive disease, was characterized by symptoms such as erythroderma, ichthyosis linearis circumflexa, atopy, and a specific hair shaft abnormality known as trichorrhexis invaginata or bamboo hair. In a reported case of a 4-year-old boy with erythroderma, growth deficit, and chronic diarrhea, trichoscopy was effectively used to identify the characteristic bamboo and "golf tee" hair, which was crucial for diagnosing Netherton syndrome. The study suggested employing trichoscopy as a diagnostic tool in all children presenting with erythroderma to aid in the diagnosis of this condition.
