A melanocytic nevus (also known as nevocytic nevus, nevus-cell nevus, and commonly as a mole) [1] [2] is usually a noncancerous condition of pigment-producing skin cells. It is a type of melanocytic tumor that contains nevus cells . [ 2 ]
In 1992, the NIH recommended that the term "dysplastic nevus" be avoided in favor of the term "atypical mole". [1] An atypical mole may also be referred to as an atypical melanocytic nevus, [2] atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, or nevus with architectural disorder. [3] Dysplastic nevi often grow to larger ...
The Skin Cancer Foundation reports that only 20 to 30% of melanomas start as existing moles. That means that 70 to 80% develop on skin that appeared to be normal. “Be familiar with the ...
The CDKN2A gene is located on chromosome 9p21.3. Two main transcripts, isoforms '1' and '4', each contain three exons and span 7288 and 26740 bp, respectively. They encode proteins of 156 and 173 amino acids; isoform '1' encodes p16(INK4a), while isoform '4' encodes p14(ARF), a protein that is structurally unrelated to p16(INK4) but acts in cell cycle G1 control by stabilizing the tumor ...

People with dysplastic nevus syndrome, also known as familial atypical multiple mole melanoma, are at increased risk for the development of melanoma. [21] Having more than 50 moles indicates an increased risk of melanoma. A weakened immune system makes cancer development easier due to the body's weakened ability to fight cancer cells. [18]
There are three types of skin cancer: Basal cell carcinoma. Squamous cell carcinoma. Melanoma ... Border that looks abnormal. C: Color that varies across the mole or is red, ...
