I had that once. The doc did a biopsy and it turned out to be cancerous. I had it removed and it was cool. Laser made it painfree and hasslefree.Have it looked at.

i dont know but you should get it checked
It could be something as harmless as fungus, but it could also be cancer, get it checked immediatly.
tongue?
Go see your PCP ASAP, even if it don't hurt.
Sometimes the upper surface of the tongue turns black or brown in color. This is an unsightly condition but not harmful.
