REPORT OF CASE
R. B., a 12 year old girl, was referred to the Northwestern University Dermatologic Clinic from the pediatric clinic because of the condition of her nails. Both thumbs show an atrophic ridge which is depressed below the surface of the nails. The ridge is present in the center of the nail and extends from the posterior nail fold to the free end of the nail surface. The fifth finger of each hand shows parallel dark lines occurring in the center of the nail plate. There are no signs of inflammation. The toe nails are not involved. This disease appeared at the age of 6 years. The malformation is not present in the parents or grandparents. There are no cutaneous manifestations or other abnormalities.
