The question: Leukonychia (or leuconychia), also known as white nails or milk spots, is a medical term for white discolouration appearing on nails. It is derived from the Greek words leuko ("white") and nychia ("nails"). The most common cause is injury to the base of the nail (the matrix) where the nail is formed.
