An intradermal nevus (also called an intradermal melanocytic nevus) is simply a classic mole or birthmark. It typically appears as an elevated, dome-shaped bump on the surface of the skin. “Nevus” refers to the mole. “Intradermal” means that the cells of the mole are located beneath the most external layer of skin..
Consequently, what is a junctional nevus?
junctional nevus (JUNK-shuh-nul NEE-vus) A type of nevus (mole) found at the junction (border) between the epidermis (outer) and the dermis (inner) layers of the skin. These moles may be colored and slightly raised.
Likewise, what is the difference between a mole and a nevus? A common mole is a growth on the skin that develops when pigment cells (melanocytes) grow in clusters. In older people, common moles tend to fade away. Another name for a mole is a nevus. The plural is nevi.
Similarly, what is a compound nevus?
compound nevus (KOM-pownd NEE-vus) A type of mole formed by groups of nevus cells found in the epidermis and dermis (the two main layers of tissue that make up the skin).
How do you remove nevus?
Small nevi can be removed by simple surgical excision. The nevus is cut out, and the adjacent skin stitched together leaving a small scar. Removal of a large congenital nevus, however, requires replacement of the affected skin.

If you notice changes in a mole's color, height, size, or shape, you should have a dermatologist (skin doctor) evaluate it.
