4 or more atypical moles Already had a melanoma A first-degree relative (parent, brother, sister, or child ) who had melanoma Your dermatologist may call an atypical mole a dysplastic (dis-plas-tic) nevus. Atypical moles are often: Larger than an eraser on the end of a pencil Have an odd shape (not round) Show more than 1 color — mixes of tan, brown, red, and pink Atypical moles can appear anywhere on the body. They often appear on the trunk. And they may appear on the scalp, head, and neck. Atypical moles rarely appear on the face. |

This mole often looks like melanoma. It can so closely resemble melanoma that a dermatologist cannot tell by looking at it. That’s because this mole is often is pink, raised, and dome-shaped. It also can have different colors in it such as red, black, and brown. The mole may bleed. It can have an opening that oozes.
Most Spitz nevi appear on the skin during the first 20 years of life. Spitz nevi also develop in adults. |

Basal cell carcinoma (BCC)
|
the most common form of skin cancer. More than two million cases of this skin cancer are diagnosed in the United States each year.
This skin cancer usually develops on skin that gets sun exposure, such as on the head, neck, and back of the hands. BCC is especially common on the face, often forming on the nose. It is possible to get BCC on any part of the body, including the trunk, legs, and arms. People who use tanning beds have a much higher risk of getting BCC. They also tend to get BCC earlier in life. This type of skin cancer grows slowly. It rarely spreads to other parts of the body. Treatment is important because BCC can grow wide and deep, destroying skin tissue and bone. |
