The diagnosis of white toenail is considered to be white nail, which can be caused by congenital genetics or can be caused by a serious nail fungus that causes the nail to turn white and appear hypertrophic, bumpy, and flaky. It can also be caused by trauma that separates the nail from the nail bed, resulting in a white color. It can also be caused by systemic diseases such as typhoid fever, acute and chronic nephritis, and renal failure. A small number of normal people can also develop pitting white nail, which is a partial or complete whitening of the nail plate, either in the form of pitting or linear white spots.
