The liver is inside the body, so it always stays moist.
There would be no dry spots on the liver. However, on the outside of the body, at the right side of the tummy just below the bottom of the ribs, is the skin on top of the liver. The skin can get rashes of dry spots, which can be evaluated by a primary care doctor or a dermatologist. The skin on top of the liver is not connected to the liver.
