I have brown arches across my finger nails. What does this signify?

The fingernails can turn every which color depending on what is going on in the body.  I didn't find much on the color brown.  It could be a fungal infection.  I found one reference to having too much flouride in the body but wasn't sure that applied either since it didn't mention a line across the fingernails but rather seemed to say the entire fingernail would discolor.  Unfortunately, I couldn't find a single photo that looks like what you are describing so not sure.  May sound like a dumb question but you haven't gotten your hand caught in a door lately?  Possible bruising?
