What is Melanonychia?
Melanonychia refers to a condition characterized by dark pigmentation in the nail bed, leading to the appearance of dark vertical lines under the fingernails. These lines can range in color from brown to black, and their presence can be a source of anxiety for many individuals. While they are often benign, in some cases, they can signal underlying health issues.
Types of Melanonychia
- Primary Melanonychia: Often hereditary, this type is usually harmless.
- Secondary Melanonychia: This type is often caused by external factors such as trauma, medications, or skin disorders.
- Systemic Melanonychia: Linked to systemic diseases, this type may require more attention.
Causes of Dark Vertical Lines Under Fingernails
There are several potential causes for the appearance of dark vertical lines under fingernails, including:

- Medications: Certain medications may lead to pigmentation changes as a side effect.
