Melanonychia: the medical term for dark stripes on nails, which can be malignant or cancerous
Dark stripes on your nails are called melanonychia. Melanonychia is a symptom that can be malignant or cancerous, and it may appear in one nail or several. The stripes are usually brown or black and look like a stripe that begins at the bottom of the nail bed and continues to the top. They can occur naturally if you have a dark complexion, and nearly all Afro-Caribbean people develop these dark pigmentations on their nails by the age of 50. Melanonychia can also be caused by a nail injury, infection, or certain drugs. Other possible causes include HIV and melanoma. A doctor can perform exams to determine whether melanonychia is malignant. If it is, the tumour or cancerous area must be removed, which may mean losing all or part of the nail.

Melanoma: a severe condition that can cause dark stripes on nails
Dark stripes on your nails are called melanonychia, and they can be a symptom of melanoma. Melanonychia is a symptom that can occur naturally in people with darker skin tones, but it can also be a sign of a more serious condition. Melanonychia may appear as brown or black stripes that start at the bottom of the nail bed and continue to the top. These stripes can occur on one or several nails.
Melanoma is a type of skin cancer that can develop in the nail bed. It is a severe condition that can be life-threatening if not treated early. When melanoma occurs in the nail bed, it is called subungual melanoma. Subungual melanoma usually presents as a stripe on one fingernail only, and the appearance of the stripe is often not linked to an injury.
If you notice dark stripes on your nails, it is important to see a doctor as soon as possible. A doctor can perform exams, such as a nail biopsy, to determine whether melanonychia is malignant or cancerous. If the tumour or cancerous area needs to be removed, you may lose all or part of your nail.
It is important to be aware of any changes to your nails, especially if they are painful, bleeding, or occur without explanation. While most cases of melanonychia are benign, it is always better to be safe and get checked by a medical professional.

Infection: an infection can also cause a dark stripe to appear
Dark stripes on your nails can be caused by a number of factors, including infection.
Infection: an infection can cause a dark stripe to appear on your nail. This is because infections can cause an increase in melanin production, which gives skin its colour. The stripe will usually appear to run from the bottom of the nail bed to the top and can occur on one or several nails. In some cases, the infection may be severe and require medical attention.
