Melanonychia: the term for dark pigmentation of the nails, which can be a natural occurrence in people with dark skin but can also indicate health issues
Melanonychia is the term for dark pigmentation of the nails, which can manifest as a single dark band or streak, or involve the entire nail. This can occur naturally in people with a dark complexion, but it can also indicate health issues. The nail plate is usually semi-transparent due to a lack of melanin, but under some circumstances, melanin can cause nail discolouration, leading to melanonychia. The discolouration can occur in one or more digits and may appear as brown or black lines that begin at the bottom of the nail bed and continue to the top.
Melanonychia can be caused by benign factors, such as biting or picking at the nails, or by more serious issues like melanoma. It is important to consult a dermatologist to confirm a diagnosis and monitor the condition, especially if there is a risk of melanoma. A biopsy is the best way to get an early diagnosis.
In some cases, dark nails can be caused by a blow to the nail, which can lead to bruising and turn the nail black, brown, or dark. This is due to the rupture of small blood vessels, causing blood to become trapped under the nail. Typically, a bruise forms shortly after the injury, and other symptoms such as pain or swelling in the finger may also emerge.

Melanoma: a dark vertical line on the nail can indicate nail melanoma, a form of cancer
Melanonychia is the term for dark pigmentation of the nails. The discolouration may be black or brown and can occur naturally in people with dark skin. However, it can also indicate health issues. A dark vertical line on the nail can indicate nail melanoma, a form of cancer. This is known as malignant melanonychia and requires the removal of the tumour, which may also include amputation of the finger or toe.
Nail melanoma is challenging to catch in the early stages because of its similarities to benign causes of melanonychia. A biopsy is the best way to get an early diagnosis. If you notice dark nails, it is important to consult a dermatologist, who can help to identify a cause and start treatment. Treatment may involve measures such as avoiding biting your nails, using antifungal medications, and, in some cases, surgery.
A blow to the nail can also lead to bruising, which can turn the nail black, brown, or dark. This is caused by the rupture of small blood vessels, which causes blood to become trapped under the nail. Typically, a bruise forms shortly after the blow, and other symptoms may emerge, such as pain or swelling in the finger.
In some cases, a dark nail may be caused by biting or picking off pieces of the nail. This can be identified by a black spot or line under the nail that does not increase in size over time and does not cause other symptoms. While targeted treatment is not required, it is still important to consult a dermatologist to confirm a diagnosis and monitor the dark nails, especially if there is a risk for melanoma.

Bruising: a blow to the nail can lead to bruising, which can turn the nail black, brown or dark
Dark nails can be caused by a number of factors. One of the most common causes is bruising, which can be the result of a blow to the nail. This can turn the nail black, brown or dark. The darkening is caused by the rupture of small blood vessels, which causes blood to become trapped under the nail. Typically, a bruise will form shortly after the injury and other symptoms may emerge, such as pain or swelling in the finger.
In some cases, dark nails can be a sign of a more serious underlying health condition. Melanonychia, for example, is a term used to describe the dark pigmentation of the nails, which can be black or brown. This can occur naturally in people with dark skin, but it can also indicate health issues. It is important to consult a dermatologist if you notice any changes in your nail colour, especially if the darkening worsens or does not improve.
Another possible cause of dark nails is nail melanoma, which can present as a dark vertical line on the nail. This can be challenging to diagnose in the early stages due to its similarities to benign causes of melanonychia. However, it is important to seek medical advice if you notice any changes in your nail colour, as early diagnosis and treatment are crucial.
Additionally, dark nails can be caused by habits such as biting or picking at the nails. This can lead to the formation of a black spot or line under the nail, which may not cause any other symptoms. While targeted treatment is usually not required in this case, it is still important to consult a dermatologist and take steps to avoid these habits to prevent further damage.

Diagnosis: an accurate diagnosis is vital as there are many possible causes of dark nails
Having dark nails can be caused by a number of factors, so an accurate diagnosis is vital. The medical term for dark nails is melanonychia, which is characterised by brown or black lines that usually look like a stripe that begins at the bottom of the nail bed and continues to the top. Melanonychia can appear in one nail or several, and can occur naturally in people with a dark complexion. However, it can also indicate health issues.
Melanonychia can be caused by a blow to the nail, which can lead to bruising and cause the nail to turn black, brown or dark. This is due to the rupture of small blood vessels, which causes blood to become trapped under the nail. A bruise usually forms shortly after the blow, and other symptoms may include pain or swelling in the finger.
Another cause of melanonychia is nail melanoma, which can be benign or malignant. Benign melanonychia often does not require treatment, but it usually does not go away by itself. Malignant melanonychia requires the removal of the tumour, which may also include amputation of the finger or toe. As cancer of the nail is challenging to catch in the early stages, a biopsy is the best way to get an early diagnosis.
Dark nails can also be caused by biting or picking off pieces of nail, which can initially be identified by a black spot or line under the nail. This spot or line usually does not increase in size over time nor does it cause other symptoms, and targeted treatment is not required. However, it is still important to consult a dermatologist to confirm a diagnosis and monitor the dark nails, especially if there is a risk of melanoma.
