Subungual melanoma, or nail melanoma, is a rare type of skin cancer that occurs under the nails. It is often diagnosed late, especially when the toe is involved, and may have already spread by the time of diagnosis. The early signs of subungual melanoma are not always noticeable, making it difficult to detect and treat early. However, it is important to note that early detection is crucial in stopping the spread of nail melanoma. When detected early, the survival rate for subungual melanoma is high, at about 95%. If diagnosed late when the cancer has already spread, the survival rate can be as low as 15%.

What You'll Learn
Subungual melanoma is hard to detect early
Subungual melanoma is a rare type of skin cancer that occurs under the nails. It is a serious condition that can quickly spread throughout the body and is lethal. It is most common in non-White racial groups, with both men and women having an equal risk. The great toe and thumb are the most commonly affected areas.
Subungual melanoma is challenging to identify because the discolouration can resemble bruising of the nails. It usually appears as a dark, vertical (from top to bottom) streak on the nail. This streak may start small but can grow over time to cover the entire nail and extend to the cuticle. The discolouration can be irregular and be varying shades of blackish-brown. The early signs of subungual melanoma are not always noticeable, which makes it difficult to detect and treat early.
Since subungual melanoma is not caused by sun exposure, it can be difficult to prevent compared to other types of melanoma. General hand and foot health can be beneficial. It is recommended to protect your fingers and toes from injury during sports and other activities by wearing the right type of gear. You should also inspect these areas regularly for any unusual changes. Knowing the signs of subungual melanoma is essential, and you should see your doctor right away if you notice any unusual changes or growths in your nail.
To correctly diagnose subungual melanoma, a doctor will conduct a physical assessment of the fingernail and may recommend a biopsy, which is a definitive test for cancer. Early detection and prompt treatment yield the best outcomes. The survival rate is high when subungual melanoma is detected early, with rates of about 95% at the early stage. If diagnosed late, the survival rate can be as low as 15%.

It spreads to other organs without early detection and treatment
Subungual melanoma is a rare type of skin cancer that occurs under the nails. It is often diagnosed later than other cancers because people are unaware of the warning signs. It usually appears as a dark line on the nail, running from bottom to top, and can grow over time. This streak may start small but can eventually cover the entire nail and extend to the cuticle.
Nail melanoma can spread to other organs and tissues in the body without early detection and treatment. The survival rate is high when detected early, with a rate of about 95% when caught and treated quickly. However, if diagnosed late and the cancer has spread, the survival rate can be as low as 15%. The key to successful treatment is early diagnosis, and the best way to achieve this is to be aware of the warning signs and regularly check your nails for any unusual changes.
The early signs of subungual melanoma can be challenging to identify, as they occur underneath the nails and may resemble bruising. Symptoms include streaks on the nails, colour changes, a bruise under the nail that does not heal, and the nails separating from the nail bed. It is important to note that subungual melanoma is not caused by sun exposure, so it can be difficult to prevent compared to other types of melanoma.
If left untreated, subungual melanoma can spread to other parts of the body, including the skin around the nail, lymph nodes, and other organs. The most severe form of subungual melanoma is stage 4, where the cancer has spread to other organs. Treatment options for metastatic melanoma may include surgery, immunotherapy, radiation, and chemotherapy. Amputation was once the standard treatment, but it is now the last resort. The decision between amputation and digit-sparing approaches depends on the patient's specific circumstances and the expertise of the healthcare provider.

It's often diagnosed late, especially when the toe is involved
Nail melanoma, or subungual melanoma, is a rare type of skin cancer that occurs under the nails. It is often diagnosed late, especially when the toe is involved, and may have already spread at the time of diagnosis. This is because the early signs of subungual melanoma are not always noticeable, and the discolouration can resemble bruising of the nails, which may not be identified as a warning sign.
Subungual melanoma usually has a distinct shape, appearing as a dark line on your nail that runs from bottom to top. This streak or stripe may start small but can grow over time, covering the entire nail and extending to the cuticle. The discolouration can be irregular and be varying shades of blackish-brown. It can also present as nail dystrophy or nail lesions, with thickening, splitting, or destruction of the nail, and pain and inflammation.
The difficulty in detecting subungual melanoma early means that it is often diagnosed at a more advanced stage than melanoma on the skin, making it more dangerous to a person's health. The survival rate for subungual melanoma is high when detected early, with a rate of about 95% for early-stage diagnoses. However, if diagnosed late and the cancer has spread, the survival rate can be as low as 15%.
To obtain a diagnosis of subungual melanoma, a biopsy is typically performed, which involves taking a small tissue sample from the affected area to test for cancer. A dermoscopy may also be performed, which involves examining the nail using a special microscope called a dermascope, allowing for a closer and more detailed inspection of the area. Early detection of subungual melanoma is crucial to prevent it from spreading to other parts of the body.

Treatment includes surgically removing the affected area
Subungual melanoma, or nail melanoma, is a type of skin cancer that develops under the nails. It is often discovered later than other cancers because people don’t know the warning signs and symptoms can be easy to miss as they occur underneath the nails. Therefore, it is important to be aware of the signs of nail melanoma and to check your nails regularly for any unusual changes or growths.
Nail melanoma usually presents as brown-black discolorations of the nail bed, which can resemble bruising of the nails. This discoloration can progress to thickening, splitting, or destruction of the nail with pain and inflammation. One tell-tale sign is a dark line on your nail that runs from bottom to top, which may start small but grow over time. This streak often does not heal or change positions as a bruise would.
If you notice any unusual changes in your nail or the surrounding skin, you should see your doctor right away. Your doctor will need to conduct a biopsy to confirm a diagnosis of nail melanoma. Early detection and treatment of nail melanoma are crucial, as it can quickly spread throughout the body. The survival rate is high when nail melanoma is detected early, at about 95% when caught and treated early. However, if it is diagnosed late and has already spread, the survival rate can drop to as low as 15%.

The survival rate is high when detected early
Subungual melanoma, or nail melanoma, is a type of melanoma that grows under the nail. It is a life-threatening form of skin cancer that can lead to serious complications if left untreated. It usually appears as a dark brown or black streak on the surface of the nail and can cause thickening, splitting, or destruction of the nail with pain and inflammation.
Nail melanoma is often detected later than other cancers because people are unaware of the warning signs. When detected early, before the cancer spreads, it is more likely to be treated successfully. The key to early detection is awareness and education. It is important to learn the signs of nail melanoma and seek medical help as soon as possible. Early detection is crucial in stopping the melanoma from spreading to other parts of the body.
The survival rate for nail melanoma is high when detected early. The 5-year survival rate is estimated to be between 15% and 80%, depending on the timing of diagnosis. When caught early and treated quickly, the survival rate is about 95%. However, if diagnosed late and the cancer has spread, the survival rate can be as low as 15%.
The thickness of the tumour also plays a role in prognosis. A lesion less than 1 mm thick has a five-year survival rate of 95%, while a lesion more than 4 mm thick has a 50% chance of survival at five years. Therefore, early detection and treatment are crucial in improving the chances of survival for people with nail melanoma.
