Twenty-Nail-Dystrophy (TND) also referred to as Trachyonychia is a disorder of the nails. It can affect all the nails hence the name. Trachyonychia is characterized by nail roughness, longitudinal ridging, fragility and hyper-pigmentation. It can occur in all ages and respond poorly to treatment. With this background, we report the case of a five year old girl with this disorder.
