A healthy one year old girl presented with ridging of all fingernails from birth in a V shaped pattern. This pattern is called a chevron or herringbone nail and is usually seen in young children. The appearance is thought to be caused by delayed development of the central part of the nail. The lateral horns of the matrix push the nail medially, causing the direction of the lines towards the midline. Shuster, who first described this pattern, preferred the term chevron nail because, unlike the herringbone, the pattern has no central “spine”. These lines usually disappear within a few years.
