A Long Brown Line Under A Young Woman's Fingernail

Slideshow

What is in your differential diagnosis for a thin brown line of parallel bands, regular in width that span nail fold to free nail edge?

The vertical brown line under the index fingernail of a African-American teen girl has not been cause for alarm over the 4-5 years she has been a patient at this clinic.
