While it's extremely rare for someone who is young to develop nail cancer, it did happen to Miss Illinois Karolina Jasko. She was only in high school when she found a vertical line under her fingernail. She didn't go to the doctor until it became infected. Then she was diagnosed with melanoma.

She was fortunate. She only lost her nail. Melanoma can spread to the entire body and can be deadly. Survival of melanoma is even more uncertain if it's found on your feet and toenails. That's because it's usually detected at an advanced stage when treatment might be too late.

While melanoma of the toenail is rare no matter what your age, it's important to be seen by a podiatrist if you have bruise under your toenail that doesn't go away.

Other Symptoms

  • A new brown or black band in the nail

  • Dark color is spilling over the skin next to the nail

  • Signs of infection such as drainage, pus, and pain

  • A bruise, splitting, or bleeding of the nail without any trauma

  • A bruise under the nail that doesn't go away with time even with trauma

Although some dark bands can be non-cancerous and caused by a bacterial or fungal infection it's important to get it checked out as soon as possible.

Sixty percent of these types of melanoma are found in the fingernails and 40% are found in the toenails. Most commonly it's found in the hallux nail or big toenail.

Risk Factors

  • Over 50

  • Personal or family history

  • Personal or family history of atypical moles

  • People of color

Unlike melanoma of the skin, melanoma of the nail is not cause by sun exposure.


Although it's not possible to prevent the condition, early identification and treatment provides the best chance for effective treatment and survival.


Treatment options depend on how early the melanoma is detected. They include surgery, chemotherapy, and radiation.
