Netherton's syndrome is a rare genodermatosis of unknown cause, which
is classified as an ichthyosiform syndrome. A clinical and immunologic
al study of seven patients with Netherton's syndrome illustrates the c
linical spectrum of this disorder, the frequent association with atopy
, and the absence of consistent immunological abnormalities. Failure t
o thrive in infancy was a feature in six of the seven patients, and wa
s considered to be life-threatening in three. The skin disease evolved
into ichthyosis linearis circumflexa in four of the seven, and the re
maining three patients suffered from persistent or recurrent ichthyosi
form erythroderma.
