What are moles?

Besides being a small burrowing mammal and a unit of chemical weight, the term mole (in reference to skin) is used to describe a variety of skin imperfections. Personally, I prefer the term beauty mark. The medical term for mole is melanocytic nevus. Moles may be tan, brown, black, reddish brown, red, purple, or skin-colored and perfectly flat or raised. Most moles are the size of a pencil eraser (about 1/2 inch).

Certain moles become darker and more apparent with sun exposure and pregnancy. They typically lighten somewhat in the winter months. Moles can occur anywhere on the skin, including the scalp, ears, eyelids, lips, palms, soles, genitals, penis, and anal area.

A melanocytic nevus (plural nevi) is composed of masses of melanocytes, the pigment-producing cells of the skin. However, there are a variety of other skin lesions that are also mole-like. These include seborrheic keratoses, skin tags, dermatofibromas, lentigines, and freckles. In this article, the term moles will be synonymous with melanocytic nevus.
