What is the meaning of epithelial dysplasia?
Epithelial dysplasia, a term becoming increasingly referred to as intraepithelial neoplasia, is the sum of various disturbances of epithelial proliferation and differentiation as seen microscopically. Individual cellular features of dysplasia are called epithelial atypia.

What is ectodermal dysplasia?
Ectodermal dysplasia is a hereditary disorder associated with abnormal development of embryonic ectodermally-derived organs including teeth, nails, hair and sweat glands. Hypodontia of the primary and permanent dentition is the most com-mon oral finding.

Ectodermal dysplasia is diagnosed by physical examination. Some children are diagnosed at birth, but milder forms of the disorder may go undetected until symptoms begin to affect the child’s daily life or development. A genetic evaluation helps determine if the condition is isolated or is part of another syndrome or condition.
What is the prevalence of ectodermal dysplasia?
Worldwide, around 1/7,000 people have been diagnosed with an ectodermal dysplasia condition. Some ED conditions are only present in single family units and derive from very recent mutations. Ectodermal dysplasias can occur in any race but are much more prevalent in Caucasians than any other group and especially in fair Caucasians.
How rare is ectodermal dysplasia?
Ectodermal dysplasia is a rare (1 : 100 000 live births), usually X-linked or autosomal recessive, condition with abnormal eccrine glands, wispy or absent hair, and abnormal teeth or nails. Numerous syndromes make up the ectodermal dysplasia group; the two main groups are the hidrotic and the anhidrotic (or hypohidrotic) forms.
What does epithelial dysplasia mean?
