Achromic Naevus

The achromic naevus is a depigmented skin spot, present from birth. It manifests as a white or pale area, often well-defined, contrasting with the rest of the skin. Unlike vitiligo, this condition is congenital and stable, without progression over time. Although its exact origin is still unknown, it could be linked to a local abnormality in melanin production.
