Abstract
Netherton syndrome (NS) is a rare genodermatosis characterized by the triad of ichthyosiform erythroderma, hair shaft abnormality and an atopic diathesis. We report a case of a 20-year-old male patient presented with pruritus, decreased sweat secretion and generalized erythema on his body. Netherton syndrome is caused by mutations in the SPINK5 gene that is a crucial role for epidermal barrier function in the skin. Different clinical and phenotypical features can occur based on various LEKTI-domains mutations. Diagnosis is made by the atopic story, hair shaft abnormality, cutaneous lesions and identification of the SPINK5 gene mutation. In our patient, we detected a new splice site mutation in the SPINK5 gene and pili annulati as hair abnormality. Affected patients are usually misdiagnosed because of cutaneous lesions such as atopic dermatitis. Therefore, each clinical finding should be evaluated together. We aimed to present a case with a new SPINK5 gene mutation and different clinical features in NS.
