What does cancer in the big toe look like and does it appear over time from a black spot -looking like you dropped something on your toe?

What does cancer in the big toe look like and does it appear over time from a black spot -looking like you dropped something on your toe?

I have a black spot: I have a black spot under my toe nail too, so I hope not. A melanoma can appear as a dark spot anywhere on your skin, including a toe, or under a toenail. Most often a black spot that looks like you dropped something on your toe is an old hemorrhage from trauma. Old blood should resorb or grow out with the skin. A melanoma, on the other hand, may have irregular coloration, an irregular border, and grow over time. ...Read more

I have a small black spot under my big toenail on my right foot. It's only been there for about 2/3 weeks. I haven't banged it.

This could be a melanoma.: Although this is relatively unlikely, it is the only potentially serious diagnosis that would concern me. I would circle it with a sharpie, but not mark directly over it. Although the nail grows slowly, this may aid your physician in making an accurate diagnosis. A melanoma will not move with the nail. In any case, you should not ignore it. ...Read more

I had a black spot show up on my toe of my right foot, it looks like a spec of dirt but black and won't scratch off wash off or anything?

Capillary leak.: Leave it alone. It is probably blood trapped beneath the skin. Some times small capillary vessels can leak a bit of blood. Days later, the blood turns a dark color. Use your camera function to take a photo for documentation. Compare the photo to the toe in a few weeks. If it enlarges, then mention it to your doctor. In all likelihood everything will be fine. ...Read more

I recently took my toe nail polish off after a couple weeks and found one of my big toes had a black spot. Is it a fungus or a bruise?

Most likely bruise: Nail trauma is common, whether from repetitive impact from running or just bumping into something. Fungal infections of the nail tend to be associated with yellowish, thickened nails. A dark spot on your nail that doesn't improve over a few weeks should be examined by a doctor to rule out the fairly rare nailbed melanoma. ...Read more
