A 3-year-old has no teeth visible on a panoramic radiograph, along with dry skin and fine wrinkling around the mouth. Which additional finding would you expect?
Show answer and explanation
Correct answer: A. Palmoplantar hyperkeratosis
This presentation (anodontia/severe hypodontia, dry/thin skin, periorificial wrinkling) is classic for hypohidrotic (anhidrotic) ectodermal dysplasia. Associated findings can include sparse hair, heat intolerance from hypohidrosis, and in some forms, palmoplantar keratoderma.
