No, tylosis itself is not contagious. It is a physical response of the skin or plant tissue to stress, pressure, or genetic factors.
A rare hereditary condition characterized by widespread thickening of the skin on the palms and soles (palmoplantar keratoderma), sometimes associated with an increased risk of oesophageal cancer.
