Skin and Soft Tissue Tumors (Moles)

Also known as nevi, moles are pigmented skin spots composed of melancoytes, or melanin-producing cells, that congregate in groups within the epidermis and dermis layers of the skin. They can appear anywhere on the skin or mucous membranes, including nail beds, are typically 3-5 millimeters in diameter, and can be light or dark in color. Some moles are flat while others are raised.

Moles can be removed by surgical excision followed by stitches, or cauterization. Small moles can be removed with a small blade in a procedure called shave excision.
