Netherton syndrome is a rare autosomal recessive disease characterized by erythroderma, ichthyosis linearis circumflexa, atopy, failure to thrive and a specific hair shaft abnormality called trichorrhexis invaginata or bamboo hair, considered pathognomonic. We report the case of a 4-year-old boy with erythroderma since birth, growth deficit and chronic diarrhea. Trichoscopy was used to visualiz...

Netherton Syndrome (AKABamboo Hair Syndrome) is a non treatable, Autosomal Recessive Disorder of infancy and childhood, so has no sex predilection. Family history may reveal consanguinity. There is triad A] Ichthyosiform linearis circumflexa B] Hair Shaft Defect like trichorrhexis invaginata & C] Atopic Diathesis. Caused by mutation in Serine Protease Inhibitor Kazal type 5 gene (SPINK5), which...

KLK5: kallikrein 5 NS: Netherton syndrome PAR2: protease-activated receptor 2 SPINK5: serine protease inhibitor Kazal type 5 Th: helper T cell TNF: tumor necrosis factor TSLP: thymic stromal lymphopoietin INTRODUCTION Netherton syndrome (NS), also known as Com elNetherton syndrome, was clinically described in 1964 by Wilkinson et al and is characterized by the triad of ichthyosis linearis circu...

Sir, Netherton syndrome (NS) is a rare autosomal recessive disorder of keratinization. It is caused by a mutation of the SPINK5 gene that encodes a multidomain serine protease inhibitor (LEKTI) predominantly expressed in epithelial and lymphoid tissues (1). Clinical presentation is characterized by the triad of (i) ichthyosis, i.e. ichthyosis linearis circumflexa (ILC) and/or congenital ichthyo...

Netherton syndrome is a rare autosomal recessive condition with variable expression. It comprises an ichthyosiform dermatitis and erythroderma of variable intensity associated with hair abnormalities and features of atopy. The pathognomic (required for diagnosis) feature is trichorrhexis invaginata identified by microscopic examination of hair shaft. Ichthyosis linearis circumflexa is ano...

Monilethrix or beaded results from a genetic abnormality of defective hair shaft formation. The altered genetics leads to improper, inefficient, incorporation of structural proteins, minerals during hair shaft formation resulting in weak, brittle hair. Other hair shaft disorders like pili torti, pili trianguli, trichorrhexis nodosa, trichorrhexis invaginata and pili annulati, rolled hair and ci...

Netherton syndrome (NS) is a rare autosomal recessive disorder, characterized by a classical triad of clinical features, including congenital ichthyosiform erythroderma, trichorrhexis invaginata, and atopic diathesis coupled with frequent bacterial infections (1). The genetic basis for the disease has been recently identified with mutations in gene SPINK5, which is involved in the regulation of...
