Netherton's syndrome: a severe neonatal disease. A case report.
A male infant was born with generalized erythroderma and scaling; the newborn demonstrated poor neonatal development and developed several complications such as hypernatremic dehydration, septicemia, gastroenteritis and seizures. In the neonatal period, the erythema faded, but exfoliation persisted. The parents are healthy but related. One older brother, who died at the age of 3 months, had shown the same clinical picture in the neonatal period and was diagnosed with congenital psoriasis. All clinical investigations, including serum immunoglobulins, complement levels and lymphocyte counts, were normal. Only raised total IgE and multiple positive specific IgE reactions were noted. Skin biopsy revealed an image of ichthyosis. Polarization microscopy of scalp hair showed trichorrhexis nodosa and discrete focal twisting of the hair shaft. This clinical picture and all histological findings are compatible with the indications of Netherton's syndrome. The purpose of this report is to call attention to this severe presentation of congenital ichthyosis in the neonatal period and to the difficulty of a correct diagnosis when confronted with congenital erythroderma.
