Melanonychia: Causes and Treatment
What is Melanonychia?
Melanonychia is a condition that causes the nails to turn brown or black. It can affect either the fingernails or toenails. Melanonychia can be caused by a variety of factors, including:
*- Fungal nail infections
- Trauma to the nail
- Certain medications
- Genetic disorders
Symptoms of Melanonychia
The most common symptom of melanonychia is a change in the color of the nail. The nail may become brown, black, or even blue-black. In some cases, the nail may also become thicker, ridged, or brittle.
Treatment for Melanonychia
The treatment for melanonychia depends on the underlying cause. If the cause is a fungal nail infection, then antifungal medication will be prescribed. If the cause is trauma to the nail, then the nail may need to be removed. In some cases, melanonychia may not require treatment.
When to See a Doctor
It is important to see a doctor if you have melanonychia. Melanonychia can be a sign of a more serious medical condition, such as subungual melanoma. Subungual melanoma is a type of skin cancer that occurs under the nail.
Outlook for Melanonychia
The outlook for melanonychia depends on the underlying cause. If the cause is a fungal nail infection, then the prognosis is usually good. If the cause is subungual melanoma, then the prognosis is more guarded.
