Melanonychia
A brown mark on your nail is called melanonychia. It is a dark vertical line on the nail that can indicate nail melanoma. It can also occur with other benign causes and requires diagnosis by a healthcare professional. The lines are brown or black and usually look like a stripe that begins at the bottom of the nail bed and continues to the top. Melanonychia may appear in one nail or several. These lines can occur naturally if you have a dark complexion. Malnutrition can also cause changes to your skin and nails. A brown line on your nails can be related to not having enough of certain nutrients in your diet, including vitamin B12 and folate.
Longitudinal melanocytosis can occur with several rare genetic disorders in which skin hyperpigmentation (excess pigmentation) is a common symptom. Genetic disorders occur because you have certain mutations in your genes. Many of these conditions are autosomal dominant, meaning that you only need to inherit the gene mutation from one parent to have the disease.
No matter the cause, it is important to have a doctor check for melanonychia because the lines may be a sign of other health issues. Many of the more serious conditions that can cause a brown line on your nail can be treated, but it's important to be diagnosed early.

Malnutrition
A brown mark on your nail could be a sign of a vitamin deficiency, such as a lack of vitamin B12 and folate, or a genetic disorder. It could also be a sign of a more serious condition, such as melanoma, and should be checked by a doctor.
If you are experiencing malnutrition, it is important to increase your intake of nutrient-rich foods. This includes foods such as fruits, vegetables, whole grains, lean proteins, and healthy fats. You may also need to take supplements to help correct any nutrient deficiencies.
In some cases, malnutrition can be caused by an underlying medical condition, such as an eating disorder, digestive problem, or chronic illness. If you are concerned that you may be malnourished, it is important to see a doctor or registered dietitian for an evaluation. They can help identify any nutrient deficiencies and recommend appropriate treatment.
If you are caring for someone who is malnourished, it is important to ensure they are getting enough nutrients and calories. This may involve helping them plan and prepare meals, encouraging them to eat, and providing nutritional supplements if necessary. In some cases, tube feeding or intravenous nutrition may be necessary to provide adequate nutrition.

Myxoid cysts
A brown mark on your nail could be caused by a few different things. Firstly, it could be a sign of malnutrition or a lack of certain nutrients in your diet, such as vitamin B12 and folate. Secondly, it could be a myxoid cyst, which is a small, benign lump that occurs near a nail. Finally, it could be a sign of melanonychia (longitudinal melanonychia), which is usually characterised by light to dark brown stripes that are parallel and regular in colour, thickness and spacing. The border will be clearly defined and less than 3mm in width. It is usually benign but can sometimes be a sign of other health issues.
While myxoid cysts themselves are not a cause for concern, it is important to be aware of other potential health issues that may be associated with them. For example, if the cysts are accompanied by bleeding, pain, or other changes in the nail, it could be a sign of an infection or other nail disease. Therefore, it is always a good idea to have any persistent or unusual nail changes checked by a healthcare professional.
If you are concerned about a brown mark on your nail, it is best to consult a doctor or dermatologist. They will be able to examine the nail and determine the cause of the discolouration. In some cases, further testing or treatment may be necessary. However, it is important to remember that many of the conditions that can cause brown marks on the nails are treatable, especially if they are caught early.
