摘要
Dyskeratosis congenital is reported in two siblings. They presented with the classic triad of mucocutaneous features: leukoplakia of the tongue, dystrophic nails, and a widespread reticulate pigmentation on the neck and upper chest. A genetic analysis was performed and a new missense mutation S356P, hemizygous, was identified in the DKC1 gene in both patients. Acitretin was started at a low-dose in both patients, resulting in clinical improvement and important, positive psychosocial effects.
