Black vertical lines on nails can be a cause for concern. Known as splinter hemorrhages, these lines can be a symptom of melanonychia, which is caused by increased melanin deposits in the nail or changes in nail pigmentation. They can also be a sign of trauma, bacterial, fungal or HIV infection, drug therapy, endocrine disorders, or excess melanin production within the nail matrix. In some cases, they may indicate a more serious condition such as melanoma or nail cancer. It is important to seek medical advice if you notice any changes in your nails, especially if there is no obvious cause.

What You'll Learn
Splinter haemorrhages
A narrow, vertical black line on your nail is called a splinter haemorrhage. Splinter haemorrhages are usually not harmful, but they can be a symptom of a type of cancer called subungual melanoma. They can also be caused by trauma, bacterial, fungal, or HIV infection, drug therapy, endocrine disorders, exogenous pigmentation, or excess melanin production within the nail matrix. If you notice changes in your nails, especially without an obvious cause, see a healthcare provider. Although gradual changes are often more harmless than sudden ones, a black line on your nail with no clear reason should still be checked. If the change happens suddenly, seek medical attention right away.

Melanonychia
A narrow, vertical black line on your nail is called a splinter hemorrhage. These lines usually start in the nail bed and extend across the entire nail. They are often the result of melanonychia, but can also be caused by trauma or infection. If you notice any changes in your nails, especially if they appear suddenly or expand rapidly, it is important to seek medical attention.
It is important to note that not all black lines on the nails are caused by melanonychia. Horizontal stripes on the nail, known as Beau's lines, are usually not harmful. However, nail discoloration in the nail bed can be a symptom of a type of cancer called subungual melanoma. This type of cancer can cause the entire nail plate to darken or change colour, creating a single-colour band or one with varying shades of brown, black, blue, or grey.
If you notice any changes in your nails, especially without an obvious cause, it is important to see a healthcare provider. Although gradual changes are often more harmless than sudden ones, a black line on your nail with no clear reason should still be checked.
