    "A tiny dent in the skin on the palm of the hand. Palmar pits are usually pink or skin-colored and can often be seen more easily after soaking the hands in water. They are often found in people with a rare, inherited condition called basal cell nevus syndrome (BCNS). People with BCNS have a very high risk of developing basal cell skin cancer and are also at risk of developing other types of cancer, including medulloblastoma.",
