What does naevus mean?
A naevus is a mark or patch on the skin that is typically darker than the surrounding skin. It can be congenital or acquired and may be flat or raised. Naevi can appear at birth or later in life and are caused by an increase in melanin. They are often harmless but can be a concern if they change in size, shape, or color. Naevi can be present on any part of the body and are more common in people with fair skin. In some cases, naevi can be a sign of an underlying medical condition, so it's essential to have them checked by a doctor. Naevi are usually benign, but it's crucial to monitor them for any changes. If you notice any unusual characteristics or symptoms, consult a dermatologist for further evaluation.
