Scalp dermatitis, distinctive hair abnormalities and atopic disease in the ectrodactyly-ectodermal dysplasia-clefting syndrome.

We report a 2-year-old girl with a combination of the ectodermal dysplasia, ectrodactyly, cleft lip/palate (EEC) syndrome, distinctive hair abnormalities, scalp dermatitis and atopic disease. To our knowledge, this is the first report of scalp dermatitis in the EEC syndrome. Distinctive structural hair abnormalities shared by the syndromes of ectodermal dysplasia and clefting are helicotrichia, pili torti et canaliculi, and cuticle defects, all of which were observed in the present case. A high incidence of atopic disease in certain subsets of ectodermal dysplasia has been reported. In our patient this manifested as food-induced exacerbation of atopic dermatitis, associated with positive prick tests and significant levels of circulating specific IgE.
