This mole can look like melanoma. In fact, it can so closely resemble melanoma that a dermatologist cannot tell by looking at it. Most Spitz nevi are pink, raised, and dome-shaped. A Spitz nevus can also have different colors in it like 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, but adults can occasionally get them.
