Hello, I'm an expert in dermatology with a focus on skin conditions and their classifications. A birthmark is a 先天性皮肤标记 that is present at birth or becomes visible shortly after birth. They are caused by the presence of an abnormal cluster of pigmented cells or blood vessels in the skin. Birthmarks can vary greatly in appearance, ranging from flat, pigmented areas to raised, fleshy growths. Some common types of birthmarks include:
1. Port-wine stains: These are flat, pink or red marks that can become darker over time.
2. Café-au-lait spots: These are light brown marks that are flat and can appear anywhere on the body.
3. Moles: These are small, dark growths that are usually brown or black.
4. Hemangiomas: These are raised, bright red growths that are caused by an overgrowth of blood vessels.
While most birthmarks are harmless, some may require medical attention if they are at risk of bleeding, infection, or if they are associated with other health conditions.

If you are born with a mole, it is considered a birthmark. People often call these birthmarks "beauty marks." But not all moles are birthmarks. Moles usually are small, round brown spots (no bigger than about the size of a pencil eraser), but they sometimes can be larger and can be different colors.
