Subungual melanoma, or nail cancer, is a rare form of skin cancer that develops under or around the nails. It is often detected later than other cancers because people mistake the warning signs for stubbed toes or infections. When detected early, subungual melanoma has a high survival rate. However, if left untreated, it can spread to other organs and tissues, reducing the chances of survival. Therefore, it is crucial to be aware of the signs, which include discoloured nails with dark brown or black streaks, and to seek medical care if any unusual changes are noticed.

What You'll Learn
Subungual melanoma is skin cancer under the nail
Subungual melanoma is skin cancer that develops under the nail. It is a rare but serious type of cancer that can quickly spread throughout the body. It is often discovered later than other cancers because people don't know the warning signs and may mistake it for a bruise or an infection. Therefore, it is important to be aware of the signs and check your nails regularly for any unusual changes.
The most common sign of subungual melanoma is a dark brown or black streak on the surface of the nail, which runs from the bottom to the top. This streak may start small but can grow over time, eventually covering the entire nail and extending to the cuticle. The discolouration can be irregular and vary in shade. In some cases, subungual melanoma may also cause the nail to separate from the nail bed, a symptom known as Hutchinson's sign.
If you notice any of these signs, it is important to see a doctor as soon as possible. A dermatologist or pathologist can examine your nail using a microscope to look for cancerous cells. A biopsy, where a small tissue sample is taken, can also be performed to confirm a diagnosis. Early detection and prompt treatment yield the best outcomes, with survival rates of up to 95% when caught early.
If subungual melanoma is diagnosed, your doctor may recommend surgery to remove the melanoma and possibly your entire nail. Other treatment options include immunotherapy, radiation therapy, and targeted therapy drugs. Amputation is now only considered in the most severe cases.
While the exact cause of subungual melanoma is unknown, certain factors can increase your risk, including having darker skin, a personal or family history of melanoma, and being older than 50. It is important to note that, unlike other skin cancers, subungual melanoma is not linked to sun exposure.

It appears as a dark streak on the nail
Subungual melanoma, or nail melanoma, is a rare but serious type of skin cancer that develops under the nail. It often goes undetected because people mistake the warning signs for stubbed toes or infections. When melanoma is spotted early, before it has spread, it has a higher chance of successful treatment.
Nail melanoma usually has a distinct appearance. It may look like a brown or black band in the nail, often on the thumb or big toe of the dominant hand or foot. However, this dark streak can show up on any nail. It typically starts as a thin line, less than 3mm wide, and grows over time. It runs from the bottom of the nail to the top, and may extend to the cuticle.
The dark streak on the nail, known as melanonychia, can be benign or cancerous. It is caused by an increase in the production and deposits of melanin in the nail. This can be due to several factors, including race, skin tone, and nutritional deficiencies. It is important to have a doctor examine any dark streaks in your nails, as they may be a sign of nail cancer or other health issues.
To diagnose melanoma under the nail, doctors use the ABCDEF criteria:
- Age in the 20 to 90-year range, most commonly in people over 50 and in those with darker skin tones.
- Band of colour that is brown-black, wider than 1/8th of an inch, with an irregular or blurred border.
- Change in size or growth rate of the band, or lack of change if the melanonychia has been treated.
- Digit involved, usually the thumb or a single digit, which is more concerning than several. Melanoma is more common in the dominant hand.
If you notice a new dark line on a single nail, especially if it fits the ABCDEF criteria, it is important to seek medical care. Early detection is crucial to prevent the cancer from spreading and to increase the chances of successful treatment.

It can spread to the skin around the nail
Subungual melanoma, or nail cancer, is a rare type of skin cancer that occurs under the nails. It appears as dark brown or black streaks on the surface of the nail. It is often discovered later than other cancers because people mistake the signs for stubbing their toe or having an infection.
Nail cancer can spread to the skin around the nail, and it is important to note any unusual changes in the nail or surrounding skin. The early signs of subungual melanoma are not always noticeable, which makes it difficult to detect and treat early. However, when found early, melanoma on the nails is highly treatable, and the survival rate is high.
To prevent the cancer from spreading, early detection is key. It is important to be aware of the signs of nail cancer and to check your nails regularly for any unusual changes. This is especially important for those with risk factors such as having darker skin, a family or personal history of melanoma, or being older than 50.
Some signs of nail cancer include discoloration or unusual damage to the nail, such as dark streaks, spots, or bands on the nail, often on the thumb or big toe. The skin around the nail becoming darker could be a sign of advanced melanoma, and nail lifting or separation from the nail bed may also indicate cancer.
If you notice any of these signs, it is important to see a doctor as soon as possible. They may recommend immunotherapy or other cancer treatments like radiation therapy. During cancer treatment, it is important to take extra care of your nails and avoid activities that could damage or injure your hands or feet.

Treatment includes surgery, chemotherapy, and immunotherapy
Subungual melanoma is skin cancer that develops under the nail. It usually appears as a dark brown or black streak on the nail surface, running from bottom to top. This streak may start small but can grow over time, sometimes covering the entire nail and extending to the cuticle. While the exact cause of nail melanoma is unknown, certain factors can increase the risk, including having darker skin, a family or personal history of melanoma, and being older than 50.
Nail melanoma can spread to other organs and tissues, and early detection is crucial to prevent this. When caught early, before the cancer spreads, the outcome is typically more successful. Treatment for nail melanoma includes surgery, chemotherapy, and immunotherapy. Here's an overview of each treatment option:
Surgery
The most common treatment for subungual melanoma is surgery. During the procedure, the healthcare provider removes the melanoma and often the entire nail. Amputation used to be the standard treatment but is now considered a last resort. Sentinel node biopsy may also be performed to examine the lymph nodes where cancer is likely to spread.
Chemotherapy
Chemotherapy can be used to treat nail melanoma, but it can also cause changes to the nails, such as horizontal ridges called Beau's lines. Chemotherapy drugs temporarily stop nail plate growth, and nails may become thinner, more brittle, and prone to lifting from the nail bed. In some cases, nails may fall off completely. These changes are usually short-term, and nails often grow back healthy after completing chemotherapy.
Immunotherapy
Immunotherapy is another treatment option for nail melanoma. It can be effective in combination with other cancer treatments like radiation therapy. However, immunotherapy can also cause skin and nail changes, such as rashes and nail bed inflammation. Some types of immunotherapy may cause severe and extensive rashes.
Regardless of the treatment method, early detection and prevention are crucial in the case of nail cancer. It is important to be aware of the warning signs and regularly check your nails for any unusual changes or discolouration.

Early detection is key to stopping it from spreading
While nail cancer is rare, it is a serious condition that requires early detection and prompt treatment. Subungual melanoma, or nail melanoma, is an aggressive form of skin cancer that develops under the nail. It usually appears as a dark, vertical streak on the nail and can spread to other organs and tissues.
Early detection is critical to stopping nail cancer from spreading. When subungual melanoma is caught early, before it has a chance to spread, the chances of successful treatment are much higher. The survival rate for nail melanoma detected early is about 95%, but if it is diagnosed late and has already spread, this rate can drop to as low as 15%.
It is important to be aware of the warning signs of nail melanoma to enable early detection. It typically appears as a dark brown or black streak on the nail, often on the thumb or big toe, but it can show up on any nail. This streak may start small but can grow over time, eventually covering the entire nail and extending to the cuticle. The discoloration can be irregular, with varying shades of brown and black. In some cases, there may also be a bump or nodule under the nail, along with the dark band.
To detect nail cancer early, it is essential to pay attention to any unusual changes in your nails or the surrounding skin. If you notice any new dark bands or streaks on your nails, it is crucial to seek medical advice promptly. A dermatologist can examine your nails using a dermoscope, a special microscope that allows for a detailed evaluation. Additionally, a biopsy, which involves testing a tissue sample from the area, can provide a definitive cancer diagnosis.
Remember, early detection is the key to stopping nail cancer from spreading and improving the chances of successful treatment. If you notice any potential warning signs, don't delay in consulting a healthcare professional.
