Clouston Syndrome with Palmoplantar Keratoderma
Clouston syndrome (hidrotic ectodermal dysplasia) is characterized by the clinical triad of nail dystrophy, alopecia and palmoplantar hyperkeratosis. Clouston syndrome is transmitted as an autosomal dominant trait and caused by mutations in the GJB6 gene (13q12), encoding the gap junction protein connexin 30 (C × 30). At present, there is no treatment for the disease and management is purely su...
متن کاملClouston syndrome can mimic pachyonychia congenita.
We studied three families suffering from nail abnormalities who had previously been diagnosed as pachyonychia congenita. No keratin gene mutations were detected. Sequencing of connexin 30 (GJB6 gene) in these patients identified heterozygous missense mutations G11R and A88V that are known to be associated with Clouston syndrome. This unexpected finding expands the Clouston syndrome phenotype an...
متن کاملClouston syndrome associated with eccrine syringofibroadenoma*
Eccrine syringofibroadenoma is a rare benign neoplasia derived from acrosyryngium cells of the eccrine sudoriferous glands. It affects the extremities of elderly individuals as solitary tumors, or may also present as multiple lesions. There are controversies about the pathogenesis and differentiation of the tumor. Eccrine syringofibroadenoma has been associated with subjacent conditions, such a...
متن کاملClouston Syndrome: 25-year follow-up of a patient*
Clouston syndrome is a rare genodermatosis that affects skin and annexes. It is a form of ectodermal dysplasia characterized by generalized hypotrichosis, palmoplantar hyperkeratosis and nail dystrophy. This paper reports a 25-year follow-up of a patient with Clouston syndrome, from childhood to adulthood, monitoring diagnosis and clinical course of the disease.
متن کاملDo you know this syndrome? Clouston syndrome*
Ectodermal dysplasias are conditions that present primary defects in two or more tissues of ectodermal origin and can be classified as hypohidrotic and hidrotic. Hidrotic ectodermal dysplasia or Clouston syndrome is an autosomal dominant genodermatosis and appears as a triad of clinical findings: palmoplantar keratoderma, nail dystrophy, and hypotrichosis. The hair is sparse and brittle. The na...
