Nail dystrophy and oral leukoplakia in a 3‐year‐old girl
Abstract
A 3‐year‐old girl with no past medical history presented to the dermatology department with a history of abnormal appearance in the fingernails and toenails. Her parents reported that the nail changes appeared during the first year of life and worsened progressively. She had a normal psychomotor development. There was no parental consanguinity, and no other family members were known to have a similar condition. On physical examination, she presented brownish discoloration and marked subungual hyperkeratosis affecting the twenty nails, causing a marked hypercurvature of the nail plate (Figure 1). Leukokeratotic plaques on the lateral borders of the tongue and buccal mucosa were observed (Figure 2). Hyperkeratotic papules on the extensor aspects of the limbs were found, some of them coalescing into plaques (Figure 3). There were no abnormalities of the hair or teeth, and she sweated normally.
