    Hi, it sounds very much like “longitudinal melanonychia” - a quite harmless line found on nails and is common with pigmented skintypes. A melanoma is very unlikely because of how long you've had it, your age, and its colour. A melanoma will tend to be darker, the nail itself can be damaged, and the pigmentation may spread from the nail to the skin edge above the base of the nail (the cuticle). A melanoma is commoner over the age of 40. Do get it checked out though, sometimes a doctor or dermatologist will use a dermatocope (a special instrument to look at the skin and nails) to check out out further.

    It is unlikely from your description of pigmentation being present for 4 years that you have a subungal melanoma.  I would have thought that in 4 years if this was a melanoma, it would have taken over most of your fingertip.

    You should see a dermatologist and it properly looked at with a dermatoscope to ensure that it is just some pigmentation in the nail bed.

    The of nail melanoma  can usually be made by simple visual inspection by a dermatologists. A small minority of patients will require  a biopsy of the nail. This is a surgical procedure.  The high death rate with nail melanoma is due to delay in diagnosis.  If you have not already done so you should see a dermatologists for assessment.

    We all agree that you can't be sure about this based on words on a website.

    Don't muck about.

    Get it looked at by a doctor.

    While longitudinal melonychia may be very common , especially in Asian and negroid races (check out Mike Tyson's nails), when it appears in a Caucasian it should be fully investigated
