What is the technical term for freckles that are small yellow to brown spots on the skin?

The technical term for freckles that appear as small yellow to brown spots on the skin is lentigines. Lentigines arise from an increase in pigmentation and are often associated with sun exposure. They are commonly seen on areas of the skin that have been exposed to the sun over time. Unlike other types of skin lesions, lentigines are flat and darker than the surrounding skin.

In contrast, macules refer to any flat, distinct, colored area of skin that could either be lighter or darker than the surrounding area, without specifying the yellow to brown characteristic. Milia are small, white cysts that typically appear on the face, particularly around the eyes and cheeks, and are entirely different from freckles. A nevus, commonly known as a mole, can vary in size, color, and elevation but is not specifically characterized as small spots like lentigines. Understanding these distinctions is crucial for accurate identification and terminology in skin conditions.
