I have had a section of my fingernail that can present a dark line, which looks like a splinter or blood blister. it runs vertically from the base of the nail to the tip. the nail itself splits at the tip along the same line.

Serious or not?: One can get benign "splinter hemorrhages" from many causes, but a persistent dark brown or black line can mean a type of skin cancer called melanoma. This should be looked at by a dermatologist.
