Solar lentigines are characterized by:
- Appearance: Flat, well-circumscribed patches that can be round, oval, or irregular in shape.
- Color: Varies from tan to dark brown or black.
- Size: Ranges from a few millimeters to several centimeters in diameter.
- Texture: Can be slightly scaly.
These spots typically appear in clusters on sun-exposed areas, particularly the face and the back of the hands. They are more numerous in fair-skinned individuals but can also be present in those with darker skin.
