A 3-year-old with anodontia, dry/soft skin, and reduced tearing—what is the underlying diagnosis?
Show answer and explanation
Correct answer: A. Ectodermal dysplasia
- A. Correct. The combination of an/oligodontia, dry skin, sparse hair, and dry eyes is hypohidrotic ectodermal dysplasia.
- B. Osteogenesis imperfecta affects bone/collagen (blue sclera, fractures), not teeth absence with dry skin.
- C. Cherubism is bilateral mandibular fibro-osseous expansion, unrelated.
- D. Hyperthyroidism does not cause anodontia.
