What is a pigmented skin blemish, birthmark, or mole known as?

The term for a pigmented skin blemish, birthmark, or mole is "nevus." A nevus is typically a benign growth of melanocytes, the pigment-producing cells in the skin, which gives it its characteristic color. Nevi can vary in appearance, size, and number among individuals and are commonly found on various parts of the body. They can be flat or raised and may change over time, but they are generally considered harmless unless they exhibit certain changes that warrant further examination.

Understanding the distinction of a nevus is important in the field of dermatology and nail technology as it aids in proper skin assessment and monitoring. Other terms like fissures, nodules, and keratomata refer to different skin conditions or formations, which do not specifically describe the characteristics of pigmented marks such as moles or birthmarks. This contextual knowledge is crucial for nail technicians as they monitor the skin surrounding the nails for any issues that may arise.
