Faint black line on finger nail
An_250665 posted:
I noticed a faint black line on my son's thump nail. It's perfectly straight from the cuticle to the tip. My son is eight years old. I have done some research online and it's pointing to subungle melanoma ? I have made an appointment with a dermatologist for next week. Any thoughts?

This could just be from bumping into or against somthing, and not remembering it. Or nutritional based. Here is a link I found on-line as the symptom checker and search here isn't working for me right now. Good Luck! Let us know what you find out.
