Overview And Scope Of The Guidelines
Melanoma is a life threatening but potentially treatable form of cancer if diagnosed and managed at an early stage. Guidelines have been published to assist healthcare workers in the recognition of malignant melanoma of the skin . However, early melanoma arising on the foot, particularly within the nail unit and on the plantar surface, can be difficult to recognise. Consequently, this can lead to delays in diagnosis. Melanoma arising on the foot carries a particularly poor prognosis when compared to melanoma arising at other body sites . As there are no consistent features of an early melanoma, these guidelines have been drafted to alert health care workers to the signs which may suggest melanoma and therefore warrant a specialist referral. A melanoma recognised and diagnosed at an early stage can dramatically increase a patient’s chances of survival.
When To See A Doctor
âYou should see a doctor as soon as you suspect you have a subungual melanoma. More generally, visit your doctor when you see a fingernail or toenail that:
- Has dark streaks
- Is starting to lift up from the nail bed
- Iâs surrounded by redness and swelling
- Has a greenish-black hue
- âShows pitting: tiny marks that look like theyâve been made by an icepick
- âTurns yellowish
- âHas deep grooves or gaps
- Lâooks thick and overgrown
- Looks thin and spoon-shaped
- Looks like you have been picking at or pulling back on the cuticle, the skin at the bottom of your nail
Can You Die From Nail Cancer
Nail cancer is not a death sentence. If treated on time, it wont lead to any serious complications. If left understand, it may develop to stage IV, where the cancer spreads to other parts of the body. If still not treated as soon as possible, the cancer could spread to other delicate organs that could lead to death.

How Can Subungual Melanoma Be Prevented
The exact cause or risk factors for Subungual Melanoma have not been identified yet. Hence, currently, it is not possible to prevent the condition.
A few steps to diagnose the condition during its early stages may include:
- Perform self-examination of your skin, from head to toe, once a month
- Get a professional skin exam from a healthcare provider, once a year
- All individuals with melanoma should undergo skin examinations regularly even after treatment, at least once a year throughout their lives
- Close monitor of individuals receiving immunosuppressants for various reasons, or those with poor immune system
How Serious Is My Cancer
If you have melanoma, the doctor will want to find out how far it has spread. This is called staging. Your doctor will want to find out the stage of your cancer to help decide what type of treatment is best for you.
The stage describes the growth or spread of the melanoma through the skin. It also tells if it has spread to other parts of your body.
Your cancer can be stage 0, 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread beyond the skin. Be sure to ask the doctor about the cancer stage and what it means for you.

Prevalence And Risk Factors
The incidence of melanoma is increasing across all ages, including a more than 600% increase in young adults from 1970 to 2009 . Melanoma is the sixth most common cancer in men and women and the second most common cancer in women ages 20 to 29 in the United States.
Based on the most recent US data, there will be about 178,560 new cases of melanoma in 2018: 87,290 in situ and 91,270 invasive. At current rates, 1 in 27 white men and 1 in 42 white women will develop an invasive melanoma over a lifetime. An estimated 9,320 people will die of melanoma in 2018: 5,990 men and 3,330 women. Apart from these statistics, if melanoma is detected and treated before it invades the deeper layers of skin, the 5-year survival rate is 99%.2,3
The primary risk factor for melanoma is exposure to UV radiation . Most melanomas arise in previously normal skin, and only 20% to 30% arise from pre-existing nevi. Although there are several genetic syndromes that predispose individuals to melanoma, these account for less than 15% of melanomas. These syndromes include xeroderma pigmentosa and familial atypical mole-melanoma syndrome .2,3
Risk Of Further Melanomas
Most people treated for early melanoma do not have further trouble with the disease. However, when there is a chance that the melanoma may have spread to other parts of your body, you will need regular check-ups.;Your doctor will decide how often you will need check-ups everyone is different. They will become less frequent if you have no further problems.;After treatment for melanoma it is important to limit exposure to the sun’s UV radiation.;As biological family members usually share similar traits, your family members may also have an increased risk of developing melanoma and other skin cancers. They can reduce their risk by spending less time in the sun and using a combination of sun protection measures during sun protection times.;It is important to monitor your skin regularly and if you notice any changes in your skin, or enlarged lymph glands near to where you had the cancer, see your specialist as soon as possible.;

Could It Just Be A Bruise
Just for some reference, here are some images of bruises of the toe and toenail for you to compare.
The marking on this toenail is a bruise. ;Note the mark goes across the nail and you can see some bruising on the skin too.
This bruised toenail has a white mark where the damage was caused and the mark looks like blood.
Where there is a marking at the base of the nail like in this image, this is usually caused by impact damage; kicking something for example.
Subungual Melanoma: Causes Symptoms And Treatment
Subungual melanoma is a form of cancer that affects the nails, wherein subungual implies beneath the nailbed in medical terminologies. This type of cancer is quite rare and is characterised by brown or black bands appearing prominently on the nails;in hands and feet, along with bleeding in the region and weak, damaged tissues. Subungual melanoma is fundamentally different from melanoma, which is a form of skin cancer that arises in melanocytes skin cells that contain pigments. Melanoma is a perilous type of skin cancer that can spread rapidly to other organs, in which distinct moles appear on the face, neck, arms parts of the body exposed to harmful UV rays, direct sunlight for extended periods of time.
Also Read: Melanoma: Causes, Symptoms And TreatmentIn subungual melanoma, the uncontrolled proliferation of cells and tumour growths begin in the nail matrix – the portion where keratin is present and which acts as a protective covering for the layer of skin below. Although this type of cancer occurs only in seldom instances, it is important to report the symptoms as soon as they are noticed on the nails. In many cases, subungual melanoma resembles an injury or bruise on the nails, so it is vital to get it examined by a medical expert at once. This helps in prompt, accurate diagnosis and timely medical treatment of subungual melanoma, to avert the spread of cancer to other organs in the body.

Biological Therapies And Melanoma
Biological therapies are treatments using substances made naturally by the body. Some of these treatments are called immunotherapy because they help the immune system fight the cancer, or they occur naturally as part of the immune system.;There are many biological therapies being researched and trialled, which in the future may help treat people with melanoma. They include monoclonal antibodies and vaccine therapy.;
What About White Streaks On Your Nails
Another possible symptom to be aware of is noticing a white streak on your nails. Some people do have white marks on their nails, but this is usually due to some sort of damage that you may have done to it. ;It is also more probable that any white marks or ridges on your nails are due to vitamin deficiency.
However, if you notice these white streaks, where you are certain you have not caused them through any other means, it is important to seek advice from your doctor as soon as possible.
It could also be a sign of toenail fungus or an infection.

Spreading To The Organs
After the cancer has spread to the lymph nodes, the lymph nodes and/or blood vessels help the cancer move to other areas of the body, like the organs. Which organ it will spread to first, varies depending on where the cancer started, the type and the person, but the liver, lungs, and brain are common sites for metastases.
Once its in the organs, it is known as stage four melanoma.
What Are The Symptoms Of Subungual Melanoma
When you hear the word melanoma, your first thought might be irregular-shaped moles on the skin caused by sun damage. But since subungual melanoma affects the nail matrix, the signs and symptoms dont look like a typical mole on the skin.
Symptoms of this condition include:
- a light- to dark-brown colored band on the nail thats usually vertical
- a dark band on the nail that slowly expands and covers more of the nail
- dark nail pigmentation that expands to the surrounding skin
- a nodule underneath the nail with or without a pigmentation band
- nail brittleness and cracking
- bleeding at the site of pigmentation
Its important to note that not all cases of this condition cause pigmentation changes in the nail. While this can make the melanoma more challenging to detect, a telltale sign of the condition is that it usually affects one nail at a time.

Dermoscopic Clues To Differentiate Pigmented Nail Bands
In the International Dermoscopy Society survey evaluating dermoscopic clues in pigmented nail bands, melanoma cases were significantly associated with :
- The width of the pigmented band occupying more than two-thirds of the nail plate
- Grey and black colours
- Hutchinson sign and micro-Hutchinson sign
- Nail dystrophy.
Granular pigmentation, a newly defined dermoscopic criterion, was found in 40% of melanomas and only in 3.51% of benign lesions. The dermoscopic feature of any pigmentation in the hyponychia is parallel pigmented lines on the ridges .
Education And Advising Clients
Despite efforts to educate the public about subungual melanoma in the last couple of decades, awareness of this type of cancer remains poor, noted the authors of a paper published in the Journal of the American Academy of Dermatology in 2018. This is why nail techs, who interact with people who might not see health care providers regularly, are a crucial piece of the detection puzzle, they wrote.

Who Gets Melanoma Of Nail Unit
Melanoma of the nail unit is rare, accounting for only about 1% melanoma in white-skinned individuals. It arises in people of all races, whatever their skin colour. Although no more common in dark skin than fair skin, it is the most common type of melanoma diagnosed in deeply pigmented individuals. It is most diagnosed between the age of 40 and 70 .
It is not thought to be due to sun exposure. Trauma may be a factor, accounting for the greater incidence in the great toe and thumb.
Management of melanoma is evolving. For up to date recommendations, refer to the Australian Cancer Council;Clinical practice guidelines for the diagnosis and management of melanoma
Have You Checked Your Nails Lately
Did you know that melanoma;and other skin cancers;can form under the fingernails and toenails? Melanoma of the nail is not widely known about, and it usually comes as a surprise that people with dark skin are affected by this type of melanoma. In fact, famous musician Bob Marley died in 1981 from an acral lentiginous melanoma, which spread to his lungs and brain from under his toenail.
In recent weeks, Dr Helena was privileged enough to not only attend but also address skin cancer doctors at the Skin Cancer College of Australasia annual congress. The Skin Cancer College Australasia a non-profit, peak body representing more than 1,000 skin cancer practitioners in both Australia and New Zealand. Around 400 doctors were in attendance during the conference.
Dr Helenas topic for this lecture was on how to diagnose melanoma and other cancers that have grown under the nail. Below is a recap of some of the key points, with tips on what to look for.
These cancers are often diagnosed late because they are relatively rare, and the biopsy is challenging. There are different types of nail-related melanoma. Subungual melanoma comes from the nail matrix;. Other nail-related cancers include ungula melanoma, which occurs underneath the nail plate, and periungual melanoma, which comes from the skin next to the nail plate.

Melanoma is the most lethal and serious type of skin cancer, with the exception of certain rare skin cancers, due to melanoma being often likely to metastasize to the internal organs and lymph nodes. 77 percent of all skin cancer-related deaths are due to melanoma, according to the American Academy of Dermatology. Being able to recognize this cancer when it is in its very early stages is crucial in surviving this skin cancer.

Subungual Hematoma As Compared To Melanoma
- Bleeding under the fingernail or toenail is considered a subungual hematoma.
- The cause of subungual hematoma is always trauma of some sort
- The symptoms are severe pain, throbbing and collection of blood which appears under the nail.
- Symptoms are due to the pressure caused by the buildup of blood under the nail bed.
- At times treatment might be to drain the buildup of blood in order to decrease pressure and pain.
- As long as there is no fracture in the bone this is acute.
- Removal of acrylic nails is indicated before any treatment can be prescribed.
- If a darkened area is noted under the nail and you do not remember a specific trauma the nail should be reviewed by a medical professional.
In this nail anatomy, you can see the distal portion of the germinal matrix which is where most subungual hematomas occur; this is also where subungual melanoma occurs. If the If the germinal matrix is injured due to the pressure buildup of a hematoma the nail may be lost.

This Is Why A New Though Tiny Spot Or Speck Should Not Be Ignored Even If It Looks Normal
Ultimately I believe genetics will help determine the behavior of these, but until we have that data we have to look at patterns, explains Dr. Gordon.
In general, survival rate of melanomas depends on depth of the cancer.
This depth is determined by a dermapathologist who examines a biopsy of the suspicious spot, which includes a surrounding margin of skin also taken out, under a microscope.
The rule of thumb is that the height of the melanoma above the surface of the skin is equal to its depth below the skin surface.
Dr. Gordon explains, In general, smaller lesions the thinner they are and the better outcomes people have.
Some melanomas will grow in a spreading pattern on the skin , but some will grow in a deep pattern that are more aggressive .
There is no easy way to decipher the spread of melanoma until it is biopsied and sometimes until further tests are performed.

Spreading to the lymph nodes. Radial melanomas are often unsymmetrical; Nodular melanoma can occur in people of all ages and all races. When a tumor gets too big, it requires more. However, because nodular melanoma grows so quickly, it is often found at a more advanced stage. How common is subungual melanoma? The factors that do not have any role to play in the rapid growth of the melanomas are age spots or liver spots, a history of sunburns, the types ok skin, the color of the. The first sign of flat melanoma is usually a new spot or an existing mole or freckle that. Fast growing melanomas are also found to occur in people who have crossed the age of 70 and in those with few moles and freckles. Melanoma that originates from the skin next to the nail plate. The incidence of melanoma is growing faster than any other type of cancer, primarily because of the popularity of sunbathing and the use of lentiginous melanoma accounts for 5% of melanomas. Knut format melanoma or nodular melanoma grows in depth from an early stage. If the melanoma is spreading through the lymph system, some of the tumor may grow there, resulting in a nodule part way between the primary site and the original lymph node.
