A classical variant of ectodermal dysplasia: a case report

Ectodermal dysplasias are characterized by abnormalities in two or more ectodermal structures, including hair, sweat glands, nails, etc. and are a rare group of congenital disorders. It is characterized by the triad of three conditions, namely hypohidrosis, hypotrichosis, and hypodontia. The phenotypic expression of ectodermal dysplasia may be variable, often raising problems in clinical assessments and care, particularly in the paediatric age group, where early manifestations can be subtle or nonspecific. While most cases reveal a clear inheritance pattern, sporadic presentations in the absence of similar complaints in the family are uncommon and raise significant diagnostic difficulties. Early identification and multidisciplinary treatment are imperative to mitigate complications such as recurrent infections, thermoregulatory dysfunction, and psychosocial impact. In this report, we highlight the clinical presentation, diagnostic evaluation, and management considerations in a 10-year-old male child diagnosed with a sporadic case of ectodermal dysplasia.
