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.
