In 1958, Netherton described the bamboo-like deformity in the fragile hairs in a girl with erythematous scaly dermatitis.[2] In 1985, Greene and Muller emphasized the triad of Netherton syndrome: ichthyosis, atopy, and trichorrhexis invaginata.[3] In 2000, Chavanas et al. identified eleven different mutations in SPINK5 in 13 families with Netherton syndrome.[4] Their finding disclosed a critica...

We report an 8-year-old boy with Netherton syndrome who was misdiagnosed and treated as severe atopic dermatitis. The diagnosis of Netherton syndrome was not made until the child was 8 years of age. We discuss the pitfalls in the diagnosis and alert physicians to the proper and early diagnosis of this syndrome. The child was treated with a low dose (0.25 mg/kg) of oral acitretin and a topical m...

BACKGROUND Tacrolimus is a macrolide immunosuppressant approved in oral and intravenous formulations for primary immunosuppression in liver and kidney transplantation. Topical 0.1% tacrolimus ointment has recently been shown to be effective in atopic dermatitis for children as young as 2 years of age, with minimal systemic absorption. We describe 3 patients treated with topical 0.1% tacrolimus ...

Netherton syndrome (NS) is a rare disorder of cornification associated with high morbidity. It caused by bi-allelic mutations in SPINK5 encoding the serine protease inhibitor LEKTI. Previous studies have shown Th17 skewing IL-23 upregulation NS, raising possibility that targeting these inflammatory pathways may alleviate disease manifestations. Ustekinumab was previously one single case to exer...
