Cancer in the fingernail, or subungual melanoma, is a rare but serious form of skin cancer that appears under the nails. It is often discovered later than other cancers because people don't know the warning signs. It is important to be aware of the signs and check your nails regularly, as the survival rate is high when subungual melanoma is detected early. This type of cancer usually appears as a dark, vertical streak on the nail, which may start small but can grow to cover the entire nail. It can also resemble a bruise, a bump, or a band of colour on the nail.

Subungual melanoma is a rare but serious type of skin cancer under the nails
Subungual melanoma is characterised by brown-black discolourations of the nail bed, which can present as either a streak of pigment or irregular pigmentation. This discolouration can progress to thickening, splitting, or destruction of the nail, with pain and inflammation. The periungual pigmentation (Hutchinson sign) is considered a pathognomonic sign of subungual melanoma. The vertical growth phase can cause nail dystrophy and ulceration, leading to cosmetic deformity.
The survival rate for subungual melanoma is high when detected early, with a rate of about 95% when caught and treated quickly. However, if diagnosed at a later stage, the survival rate can drop to as low as 15%. Therefore, it is important to learn how to identify subungual melanoma and seek early treatment. A dermoscopy or a biopsy can be performed to confirm the diagnosis.
To identify subungual melanoma, look for a brown-black coloured band on your nail that is larger than three millimetres in size with irregularly shaped edges. It will be located in the nail bed of your thumb, big toe, or index finger and will grow over time. It is important to note that nail melanoma is often discovered later than other cancers because people mistake the warning signs for injuries or infections.

It usually appears as a dark, vertical streak on the nail
Cancer in the fingernail, or subungual melanoma, is a rare but serious form of skin cancer. It usually appears as a dark, vertical streak on the nail, running 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 from brown to black.
Subungual melanoma is often discovered later than other cancers because people don't know the warning signs and may mistake it for a bruise, an injury, or an infection. However, it is important to note that this type of cancer is not linked to sun exposure. It is most likely to develop on the big toe, thumb, or index finger.
If you notice any suspicious changes to your nails, such as a dark streak, it is best to make an appointment with a healthcare provider. They will examine your nail and review your medical history to determine if you are at high risk for subungual melanoma. Your doctor may use a special microscope called a dermascope to get a closer look or perform a biopsy to definitively diagnose cancer.
The survival rate for subungual melanoma is high when detected early, with rates of about 95% when caught and treated quickly. However, if the cancer spreads, the survival rate can drop to as low as 15%. Therefore, it is crucial to be vigilant about any changes in your nails and seek medical advice if you have any concerns.

It can also resemble a bruise, a bump, or a band of colour
Cancer in the fingernail can manifest in several ways, some of which may resemble a bruise, a bump, or a band of colour. It is important to be vigilant and consult a healthcare provider if you notice any suspicious changes in your nails.
One of the most common types of cancer that affects the fingernail is subungual melanoma, also known as nail melanoma. This form of cancer typically appears as a dark, vertical streak on the nail, often starting small and growing over time to cover the entire nail. These streaks may be brown or black and can be mistaken for a bruise. In some cases, nail melanoma may also exhibit "Hutchinson's sign," where the nail pigment extends onto the surrounding skin. Additionally, onycholysis, or nail lifting, is a common symptom, where the nail detaches and separates from the nail bed.
Nodular melanoma, another form of nail cancer, presents as a bump or nodule beneath the nail. This type of cancer may cause the nail to appear pushed up and detached from the nail bed. Demoplastic melanoma, while more commonly found near the neck and head, can also occur on the skin near the nails.
In rare cases, cancer in the fingernail may be associated with an underlying benign tumour abnormality known as onychopapilloma. This condition often manifests as a coloured band, usually white or red, along the length of the nail. It is typically found on a single nail, but in individuals with BAP1 tumour predisposition syndrome, onychopapilloma tumours may affect multiple nails.
It is important to remember that many conditions can affect the appearance of the nails, and a definitive diagnosis can only be made through a medical evaluation and, if necessary, a biopsy. Early detection and treatment of nail cancer are crucial for a successful outcome.

It can be diagnosed through a dermoscopy or a biopsy
Subungual melanoma, or nail melanoma, is skin cancer that develops under the nail. It usually appears as a dark, vertical streak on the nail and can be identified through a dermoscopy or a biopsy.
A dermoscopy involves a healthcare provider examining the nail using a special microscope called a dermascope. This allows them to closely inspect the area in greater detail. However, a dermoscopy may not always be conclusive, and a biopsy may be necessary for a definitive cancer diagnosis.
During a biopsy, a tissue sample from the area is extracted and tested for melanoma. This simple and safe surgical procedure can provide valuable diagnostic information and aid in understanding the nature and progression of nail diseases. It is important to select the appropriate area for the biopsy, as different techniques are used for the nail plate, nail bed, nail fold, and nail matrix.
The nail plate biopsy is the simplest and least scarring option, where a portion of the nail plate is removed with scissors or a nail clipper. In contrast, the nail bed biopsy involves avulsing the nail or using a punch biopsy tool to extract a sample directly through the nail plate. The nail matrix biopsy can result in scarring and carries its own risks and side effects due to the delicate nature of the matrix, a crescent-shaped structure at the nail's base.
While a dermoscopy can provide a detailed visual inspection, a biopsy is a more invasive procedure that involves taking a physical sample for analysis. Both methods play a crucial role in the diagnosis and treatment of nail cancer, helping healthcare providers make accurate assessments and determine the best course of action for patient care.

The survival rate is high when subungual melanoma is detected early
Subungual melanoma, or nail melanoma, is a rare form of skin cancer that occurs under the nails. It is an aggressive form of melanoma that arises from structures within the nail apparatus. It is not linked to sun exposure, unlike other skin cancers. Subungual melanoma usually appears as a dark, vertical streak on the nail, often with an ill-defined border. It can also cause colour changes, bruising, and the nail separating from the nail bed.
The survival rate for subungual melanoma is high when detected early. The outlook for subungual melanoma depends on its stage at diagnosis and the patient's response to treatment. When caught early before the cancer spreads, subungual melanoma is more likely to be successfully treated. The survival rate is about 95% when detected early and treated quickly. However, if diagnosed late when the cancer has spread, the survival rate can be as low as 15%.
It is important to learn the warning signs of subungual melanoma to facilitate early detection and treatment. When checking for signs of skin cancer, people often forget to examine their nails. Subungual melanoma usually has a distinct appearance, with a dark line running from the bottom to the top of the nail. This streak may start small but can grow over time, even covering the entire nail and reaching the cuticle. The discolouration can be irregular, with varying shades of blackish-brown.
To diagnose subungual melanoma, a doctor will examine the nail and review the patient's medical history. They may perform a dermoscopy, using a microscope to examine the nail closely. A biopsy, which involves testing a tissue sample from the nail, can provide a definitive cancer diagnosis. Treatment options for subungual melanoma include surgical removal of the affected nail or digit, radiation therapy, chemotherapy, and immunotherapy.
