Toe Nail Fungus or Melanoma?

It Is Possible
It is possible to develop melanoma in the nail matrix, which is the cell line that grows your nail plate. This would cause a brown or black line in the actual nail plate itself. Sometimes, this can cause dyspigmentation at the nail cuticle as well called a "Hutchinson's sign" but not always. The best way to determine if you have a melanoma, or just abnormal nail coloring from the fungus, is to see a Dermatologist in person. The Dermatologist can generally look at the nail/finger itself and determine the diagnosis, but occasionally, he/she may need to do a biopsy as well to rule out the diagnosis of melanoma. As melanoma is a very aggressive and potentially life threatening condition, I would recommend having the evaluation quickly. I hope that helps.
Dark Spot on Your Toenail
I would advise you to have your dermatologist examine this dark spot. There are certain types of fungal and bacterial infections of the toenail that can give a dark appearance, but melanoma can cause this, as well. It is best to have a dermatologist examine it and determine what the cause may be.
