What is dysplastic nevus syndrome?

A condition called dysplastic nevus syndrome, also known as familial melanoma syndrome or familial atypical multiple mole melanoma syndrome, can increase a person's risk for developing melanoma. A "nevus" is a mole. These particular moles are often irregularly shaped and may be larger than other moles. They can appear anywhere on the body, sun-exposed or not. This condition tends to run in families. A person with this condition may have many moles on her body or just a few. Researchers believe that a genetic predisposition for dysplastic nevus syndrome may exist.
