What You'll Learn
Melanonychia
The nail plate is usually semitransparent because of a lack of melanin, the substance responsible for skin pigmentation. However, under some circumstances, melanin can cause nail discolouration, leading to melanonychia. The discolouration can occur in one or more digits and can present as a single dark band or streak. It is important to note that melanonychia can have many different causes that range from harmless to potentially fatal. Therefore, it is recommended to always have a doctor examine any dark streaks in your nails to ensure an accurate diagnosis.
Hormones and certain medications can also cause pigmented bands in the nails. However, be especially watchful for nail cancer symptoms, such as a brown or dark stripe that goes from the cuticle to the free edge of the nail, especially if it is getting wider. If the brown pigmentation on your nails is round, as opposed to linear, it could be another condition, such as nail psoriasis.

Nail psoriasis
Brown spots on nails can be a sign of nail psoriasis. Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales. These patches normally appear on the elbows, knees, scalp, and lower back, but they can also appear on the nails.
There is no cure for nail psoriasis, but treatments can help to manage the condition. Topical treatments, such as creams and ointments, can be applied directly to the nails to help reduce inflammation and improve the appearance of the nails. Oral medications, such as retinoids and immunosuppressants, can also be used to treat nail psoriasis. In some cases, phototherapy, or light therapy, may be recommended.
It is important to see a doctor or dermatologist if you notice any changes in your nails, such as brown spots or pitting. They can examine your nails and determine the underlying cause of the changes.

Melanoma
Brown spots on nails can be a sign of melanoma, a type of nail cancer. Melanoma is a potentially fatal condition that can affect the fingernails or toenails. It is characterised by a brown or black stripe that runs from the cuticle to the free edge of the nail, and it may be getting wider over time. This type of linear pigmentation is known as longitudinal melanonychia or melanonychia striata.
Melanonychia is the term for dark pigmentation of the nails, which can be brown, black, or grey. It can occur in one nail, several nails, or all of the nails, and it may be a natural occurrence in people with dark skin. However, it can also indicate health issues, so it is important to have any dark streaks in the nails examined by a doctor. Melanonychia can have many different causes, ranging from harmless to potentially fatal.
Nail melanoma is often discovered later than other cancers because people are unaware of the warning signs. It is important to learn how to spot nail melanoma to increase the chances of early detection and successful treatment. Subungual melanoma, or nail melanoma, usually has a distinct shape, resembling a line drawn on the nail with a black or brown marker. It appears as a dark line running from the bottom to the top of the nail.
If you notice any brown pigmentation on your nails, especially if it is pitted or accompanied by other symptoms, it is important to consult a dermatologist for an accurate diagnosis. Early detection and treatment of nail melanoma can significantly improve the chances of a successful outcome.
