Leukonychia totalis. This is a rare nail disorder that is inherited in
autosomal dominant fashion. The color of normal nail plates beyond the lunulae
is largely pink from the blood in the blood vessels of the nail bed. The
whiteness shown here is due to an abnormality in the nail plate. The nails may
also be brittle.
