Have you ever noticed a strange black or brown line on your fingernail or toenail? It might look like it was just drawn with a pen. Many people think it's just a bruise or a small infection. However, it may not be as simple as we think. It could be a type of skin cancer called Subungual Melanoma , which develops under the nails. So let's talk about this in more detail today, because it's very important to be aware of this.
So, what is this (Subungual Melanoma)?
Simply put, Subungual Melanoma is a type of skin cancer that develops under your fingernail . To be precise, it is a nail cancer. It usually appears as a dark, vertical line running from top to bottom along the nail. Subungual Melanoma is a rare but very dangerous type of skin cancer . Doctors call it ``Acral Lentiginous Melanoma.'' It is a type of skin cancer that is more aggressive and can spread quickly. Unlike other skin cancers, Subungual Melanoma is not caused by sun exposure . It is most likely to develop on the nails of your big toe, big toe, or index finger.
This nail cancer develops in the area where the nail grows, called the nail matrix . The nail matrix is the part of your nail bed (the pink tissue under the nail) that is just below the skin. It also contains nerves, blood vessels, and lymph nodes. While other skin cancers start on the surface of the skin, nail cancer starts in special cells called melanocytes . These melanocytes produce the pigment called melanin that gives our skin its color. When these cells become activated for some reason, melanin production increases. This is called hyperpigmentation . That's when those vertical lines under the nail become visible.
Many people think that when the color of the nail changes, it is because the foot was hit somewhere, or because of some infection. Therefore, this nail cancer is often detected later than other cancers. Because, people do not know the warning signs of this. Therefore, knowing what are the symptoms of this nail cancer will help you get treatment as soon as possible. If (Subungual Melanoma) is detected early (that is, before the cancer spreads), the chances of recovery are much higher .
What does this look like? What are the characteristics?
Subungual Melanoma usually looks very distinctive . Some people say it looks like someone has drawn a line on the nail with a black or brown marker. It looks like a dark line that runs from the bottom of the nail up. This line may be small at first, but over time it can grow to cover the entire nail and extend to the cuticle . This discoloration is not uniform, but can be a variety of shades of black or brown.
Usually, a single colored line is less than 3 millimeters wide (about the width of two pennies pressed together), but it can widen over time. The lines can increase in number and become larger. The widening of the line most often begins at the base of the nail. In some cases (Subungual Melanoma), the nail color does not change. Instead, a small, irregularly shaped lump (`nodule`) may form that may rise above the nail or the nail may be damaged in other ways.
Who is more likely to develop this?
Anyone can develop subungual melanoma. However, if you are between the ages of 50 and 70 and have darker skin , you are at higher risk of developing this cancer under the nail. It is more common in people of African-American, Asian, or Hispanic descent.
How common is this condition?
Subungual Melanoma is a very rare condition , accounting for between 0.7% and 3.5% of all melanoma cancers reported worldwide.
What are the symptoms of nail cancer?
The main symptom of subungual melanoma is a discolored line that appears on the nail . This is usually brown or black in color, and runs vertically from top to bottom. Sometimes, this line can be irregular in shape and can increase in length and width over time.
If you have Subungual Melanoma, your nail may look like this:
- The nail may split, crack, or change shape.
- The pigment may be irregular (meaning the color is not evenly distributed).
- There may be swelling or inflammation.
- The nail can lift off the bed.
- A wound, a lump may develop, or it may start to bleed.
- The skin around the nail may change color (this is called the Hutchinson sign).
Sometimes, there is no change in the color of the nail at all. That's why it's important to pay attention to anything strange or different about your nail, especially if you don't remember hitting or injuring it somewhere.
Subungual Melanoma can be easily confused with a nail infection or bruise, so if you notice something strange under or on your nail, it's best to see a doctor to have it checked out.
See a doctor if you notice any of these changes in your nails:
- If the color changes.
- If the shape changes.
- If it starts to lift up, to escape.
- If the thickness changes.
- If it suddenly looks like holes.
Why does this (Subungual Melanoma) occur? What are the causes?
The exact cause of subungual melanoma is still unknown . Medical experts know that it is more common in older people with darker skin tones. Unlike many types of melanoma, it is not caused by sun exposure. Injury or trauma to the nail may be a risk factor. Genetic factors, a family history of this type of cancer, and skin moles can also play a role.
How does a melanoma start? How quickly does it spread?
Subungual Melanoma usually starts as a small, dark spot under the nail . Over time, this discoloration can become wider and irregular. The nail is usually damaged, such as cracking or peeling. As the cancer gets worse, it can start to bleed.
This nail cancer can take several months to develop. It doesn't happen overnight. You may see it, then forget about it, and then see it again a few weeks later.
How do I know for sure if I have (Subungual Melanoma)?
Your doctor will determine if you have subungual melanoma by examining your nail and reviewing your medical history. They will look at whether your nail looks similar to a subungual melanoma and whether you are at increased risk of developing the condition.
The most important thing is not to ignore any changes in your nails. If you have any doubts, it is best to see a doctor for advice.
What kind of tests are done to confirm this?
There are limitations to just looking at your nail with your eyes. It can be confused with other conditions or an injury. Therefore, your doctor may perform a ``Dermoscopy`` (skin examination) or ``Biopsy`` (examination of living tissue) .
- Dermoscopy is when a doctor examines your nail with a special microscope (called a dermascope). This allows them to see the area in more detail.
- A biopsy can tell for sure if there is cancer. This involves taking a tissue sample from the area and testing it for melanoma. The doctor uses a tube-like instrument to take a small piece of tissue.
Other tests may be done to see if the cancer has spread to other areas.
What are the treatments for Subungual Melanoma?
In the past, the standard treatment for subungual melanoma was to amputate the affected finger (`amputation`), but now it is only done as a last resort .
The main treatment for subungual melanoma is surgery . Your doctor will perform surgery to remove the melanoma, and often your entire nail.
Like other types of cancer, nail cancer can spread to other organs and tissues. Your doctor may do something called a ``Sentinel Node Biopsy`` (this looks at the lymph nodes where the cancer is most likely to spread). They may also recommend other cancer treatments, such as ``Immunotherapy`` or ``Radiation Therapy`` . All of this is done to give you the best possible outcome.
Can this nail cancer spread?
Yes, (Subungual Melanoma) can spread , especially to the skin around the nail. Therefore, it is very important to be aware of any unusual changes in your nail or the skin around it. The best way to stop (Subungual Melanoma) from spreading is to recognize it early .
What is the cure rate if you develop (Subungual Melanoma)?
(Subungual Melanoma) has a very high survival rate if detected early . If detected early and treated promptly, the survival rate is about 95% . However, if (Subungual Melanoma) is detected late and the cancer has spread, the survival rate can be as low as 15% . Do you see the value of early detection?
What are the risk factors for developing Subungual Melanoma?
Although the exact cause of nail melanoma is unknown, doctors believe that these factors may increase the risk:
- Darkening of the skin.
- Someone in your family or you yourself have had melanoma before.
- Being over 50 years of age.
Since subungual melanoma is not directly caused by sun exposure or exposure to harmful substances, it is a little difficult to prevent. The best thing you can do is to be aware of it and regularly check your nails for any discoloration or unusual damage.
What questions should I ask the doctor?
If you are diagnosed with melanoma, you may have many questions. It is normal. You may ask questions like:
- Can Subungual Melanoma be cured?
- What are the chances of Subungual Melanoma recurring?
- Do I need chemotherapy or radiation therapy?
- Is there a risk of melanoma in my family?
- Is there anything I can do to prevent this from happening again?
What is the difference between a subungual melanoma and a subungual hematoma?
A subungual hematoma is a collection of blood under your nail . This usually happens when you have an injury or wear tight shoes. A subungual melanoma looks like a dark line, while a hematoma looks like a dark bruise or spot under your nail . A hematoma may bleed when you cut your nail, or the blood may come out with the nail. A hematoma can appear quickly, within a few hours of the injury. A melanoma grows slowly .
However, sometimes it can look like a hematoma. If you have any doubts or notice something strange under your nail, it's best to see a doctor .
So what are the most important things we need to remember from this? (Take-Home Message)
Knowing the symptoms of Subungual Melanoma is the best thing you can do for this type of skin cancer. If you notice a dark line or other unusual change in your nail, be sure to see a doctor.
