I have a faint brown line that funs the length of my fingernail and starts at the cuticle. It is not painful and it has not given me any problems. It showed up about 3 months ago and I don't have a clue as to what it could be. Does anyone know or have the same problem?
Benign means it isn't cancerous, Malignant means it is. Either way, it should be removed if it is a growth in the matrix. Only your dermatologist would be able to diagnosis the actual problem and suggest a remedy. It could also be an infection of the matrix, but there again, it is a medical condition that needs to be properly diagnosed.
