Spitz naevi or spitz's nevi are skin lesions that usually affect the face or limbs of young children. They grow rapidly at first, then may remain static for years. They often disappear spontaneously after a period of time. Spitz naevi have also been called juvenile melanomas because they resemble malignant tumors clinically and microscopically, but the Spitz naevi are actually benign. Spitz naevi are typically dome-shaped red, reddish-brown or darker bumps or blisters up to one or two centimeters in diameter. It is not known why spitz nevi occur. They seen most often in children and fair-skinned individuals.
