A wide range of hereditary diseases affecting two or more ectodermally derived tissues together are referred to as ectodermal dysplasias (EDs). The most frequently impacted ectodermal derivatives are the teeth, nails, sweat glands, and hair. The mucous membranes of the mouth and nose, lips, eyes, ears, and other ectodermal structures could also be impacted. During embryonic development, the ectoderm forms the outermost layer of the primary germ layers that give rise to the several structures that are commonly affected in ED. As a result, depending on the array and severity of the anomaly, ED presents itself differently in each patient. This symptom is present in 1 in 50,000 people worldwide. Among these 150 unique syndromes, hypohidrotic (faulty sweat glands) and hidrotic (normal sweat glands) syndromes are the most prevalent. Moreover, there are many inheritance patterns associated with ED, with X-linked inheritance being by far the most prevalent. Here, we report on a seven-year-old boy's clinical case of hypohidrotic (anhidrotic) ED.
Hypo hidrotic Ectodermal Dysplasia is a genetic skin disease which is inherited in an X - linked recessive, Autosomal Recessive (or) Autosomal Dominant pattern. Common symptoms include sparse scalp & body hair reduced ability to sweat and missing teeth. The incidence of this disease globally is 1 in 50,000 population.
A 14-year-old boy presented with complaints of reduced sweating, sparse hair growth over the scalp, absence of teeth, dryness of skin since birth. Complaints of heat intolerance present during summer, exercise and having spicy food. History of visible nasal deformity present since birth. History of similar complaints in the family present (Patient had a sibling with similar presentation who passed away at the age of 2).
Hence diagnosed as Hypo hidrotic Ectodermal Dysplasia.
A suspected diagnosis of Hypo hidrotic Ectodermal Dysplasia should be accompanied by a thorough history and physical examination. A family history is important in identifying familial cases and should focus on pigment abnormalities, premature graying of the hair, hearing loss, and gastrointestinal complications. A detailed physical examination should be performed with particular attention to the hair, skin, oral cavity & nasal cavity.
ED is a broad category of genetic illnesses marked by birth abnormalities of one or more ectodermal structures, such as appendages of the skin. All mendelian mechanisms of inheritance have been observed, and the prevalence of ED is estimated to be seven per 10,000 births.
It is important to counsel and advise parents to keep their kids away from physically demanding activities and intense heat. Other typical symptoms of ED that should be treated symptomatically include xerostomia, atopic dermatitis, and dryness of the nose and eyes. It is recommended that all hypo hidrotic ED patients see a dentist. Hypo hidrotic ED patients are more prone to melancholy, low self-esteem, and insecurity due to their unusual physical characteristics and lack of social acceptance.
Managing Hypohidrotic Ectodermal Dysplasia involves a multidisciplinary team approach, patient education, and early intervention in selected patients. All patients with this condition, and their families, should be offered genetic counselling and testing.
Classification of EDs is difficult due to their heterogeneous grouping of inherited disorders with overlapping symptoms. Those who experience clinical indications face significant social challenges. It is typically necessary to diagnose early and formulate rehabilitation through interdisciplinary teamwork. A multidisciplinary team of physicians, comprising pediatricians, ENT specialists, and skilled dentists, is frequently required to treat the patients. Furthermore, to help ED sufferers maintain their sense of self-worth, psychologists' assistance is typically necessary.
