Clinical Classification

Clinical Information

  • Ectodermal Dysplasia

    a group of hereditary disorders involving tissues and structures derived from the embryonic ectoderm. they are characterized by the presence of abnormalities at birth and involvement of both the epidermis and skin appendages. they are generally nonprogressive and diffuse. various forms exist, including anhidrotic and hidrotic dysplasias, focal dermal hypoplasia, and aplasia cutis congenita.
  • Ectodermal Dysplasia 1, Anhidrotic

    an x-linked form of ectodermal dysplasia which results from mutations of the gene encoding ectodysplasin.
  • Ectodermal Dysplasia 3, Anhidrotic

    an autosomal dominant form of ectodermal dysplasia which is due to mutations in the gene for the edar receptor.
  • Ectodermal Dysplasia, Hypohidrotic, Autosomal Recessive

    an autosomal recessive form of ectodermal dysplasia which is due to mutations in the gene for the edar receptor or edar-associated death domain protein.
  • Focal Facial Dermal Dysplasias

    a heterogenous group of genetic disorders characterized by scar-like atrophic lesions on the temple region of the head including preauricular area. location of skin defects is likely related to defects in fusion of embryonic facial prominences during development of the face. focal facial dermal dysplasia (ffdd) is generally divided into four subtypes according to the location of the lesions and inheritance pattern: ffdd1 (brauer syndrome); ffdd2 (brauer-setleis syndrome); ffdd3 (setleis syndrome); and ffdd4. mutations in twist2 protein and/or cyp26c1 (see cyp26 family) are associated with ffdd3, and 4.
  • Acanthosis Nigricans

    a circumscribed melanosis consisting of a brown-pigmented, velvety verrucosity or fine papillomatosis appearing in the axillae and other body folds. it occurs in association with endocrine disorders, underlying malignancy, administration of certain drugs, or as in inherited disorder.
  • Hypohidrosis

    abnormally diminished or absent perspiration. both generalized and segmented (reduced or absent sweating in circumscribed locations) forms of the disease are usually associated with other underlying conditions.

Skin Conditions

What does your skin do?

Your skin is your body's largest organ. It covers the entire outside of your body. There are many ways that your skin protects your body and helps keep you healthy. For example, it:

  • Holds body fluids in, which helps prevent you from getting dehydrated
  • Keeps out harmful germs, which helps prevent infections
  • Helps you feel things like heat, cold, and pain
  • Helps control your body temperature
  • Makes vitamin D when the sun shines on it
  • Shields your body against heat and light

What problems and conditions can affect your skin?

There are many different problems and conditions which can affect your skin. Some of them can cause uncomfortable symptoms, such as itching, burning, redness, and rashes. They might also affect your appearance. Some of the more common skin conditions include:

  • Acne, which causes pimples when hair follicles under your skin get clogged up
  • Burns
  • Cuts and scrapes
  • Dandruff, flaking of the skin on your scalp (the top of your head)
  • Eczema (atopic dermatitis), which causes inflammation, redness, and irritation of the skin
  • Hives, which are red and sometimes itchy bumps on your skin
  • Insect bites
  • Psoriasis, which causes itchy, scaly red patches
  • Skin cancer
  • Skin infections

How can I keep my skin healthy?

Since your skin protects your body in many ways, it's important to try to keep your skin healthy. For example, you can:

  • Wear the right protective equipment, like gloves, long sleeves, knee and elbow pads, or helmets to protect against cuts, bumps and scrapes.
  • If you do get a cut or scrape, clean it right away with soap and warm water. Put on a bandage to protect it while it heals.
  • When you are spending time outdoors, wear long sleeves and pants and use insect repellant to prevent insect bites.
  • Prevent sunburn by covering up and using sunscreen when outdoors.
  • Wash your hands often with soap and water.
  • When you take a shower or bath, use warm (not hot) water. Use mild cleansers and wash gently (don't scrub).
  • Use moisturizers, like lotions, creams, or ointments, to prevent dry skin.

Anhidrotic ectodermal dysplasia with immune deficiency

Anhidrotic ectodermal dysplasia with immune deficiency (EDA-ID) is a form of ectodermal dysplasia, which is a group of conditions characterized by abnormal development of ectodermal tissues including the skin, hair, teeth, and sweat glands. In addition, immune system function is reduced in people with EDA-ID. The signs and symptoms of EDA-ID are evident soon after birth, and due to the severity of the immune system problems, most people with this condition survive only into childhood.

Skin abnormalities in children with EDA-ID include areas that are dry, wrinkled, or darker in color than the surrounding skin. Affected individuals tend to have sparse scalp and body hair (hypotrichosis). EDA-ID is also characterized by missing teeth (hypodontia) or teeth that are small and pointed. Most children with EDA-ID have a reduced ability to sweat (hypohidrosis) because they have fewer sweat glands than normal or their sweat glands do not function properly. An inability to sweat (anhidrosis) can lead to a dangerously high body temperature (hyperthermia), particularly in hot weather and during exercise, because the body cannot cool itself by evaporating sweat.

The immune deficiency in EDA-ID varies among individuals with this condition. Children with EDA-ID often produce abnormally low levels of proteins called antibodies or immunoglobulins. Antibodies help protect the body against infection by attaching to specific foreign particles and germs, marking them for destruction. A reduction in antibodies makes it difficult for children with this disorder to fight off infections. In EDA-ID, immune system cells called T cells and B cells have a decreased ability to recognize and respond to foreign invaders (such as bacteria, viruses, and yeast) that have sugar molecules attached to their surface (glycan antigens). Other key aspects of the immune system may also be impaired, leading to recurrent infections.

Children with EDA-ID commonly get infections in the lungs (pneumonia), ears (otitis media), sinuses (sinusitis), lymph nodes (lymphadenitis), skin, bones, and gastrointestinal tract. Approximately one quarter of individuals with EDA-ID have disorders involving abnormal inflammation, such as inflammatory bowel disease or rheumatoid arthritis.

There are two forms of EDA-ID that have similar signs and symptoms and are distinguished by the modes of inheritance: X-linked recessive or autosomal dominant.

Hypohidrotic ectodermal dysplasia

Hypohidrotic ectodermal dysplasia is one of more than 100 types of ectodermal dysplasia. Starting before birth, these disorders result in the abnormal development of ectodermal tissues, particularly the skin, hair, nails, teeth, and sweat glands.

Most people with hypohidrotic ectodermal dysplasia have a reduced ability to sweat (hypohidrosis) because they have fewer sweat glands than normal or their sweat glands do not function properly. Sweating is a major way that the body controls its temperature; as sweat evaporates from the skin, it cools the body. Reduced sweating can lead to a dangerously high body temperature (hyperthermia), particularly in hot weather. In some cases, hyperthermia can cause life-threatening health problems.

Affected individuals tend to have sparse scalp and body hair (hypotrichosis). The hair is often light-colored, brittle, and slow-growing. Hypohidrotic ectodermal dysplasia is also characterized by several missing teeth (hypodontia) or teeth that are malformed. The teeth that are present erupt from the gums later than usual and are frequently small and pointed.

Some people with hypohidrotic ectodermal dysplasia have distinctive facial features, including a prominent forehead, thick lips, and a flattened bridge of the nose. Additional features of this condition can include thin, wrinkled, and dark-colored skin around the eyes; chronic skin problems such as eczema; and a bad-smelling discharge from the nostrils (ozena).

Intellectual ability and growth are typically normal in people with hypohidrotic ectodermal dysplasia.
