Additional recommended knowledge
Types of Leukonychia
This condition is whitening of parts of the nail. There are several types of this condition.
Leukonychia Striata or Transverse Leukonychia
This is a whitening or discoloration of the nail in bands or "stria". It may be caused by cirrhosis, chemotherapy, or physical injury to the nail matrix. (i.e. excessive nail "tapping" or slamming in a car door).
This is the most common form of Leukonychia, small white spots on the nails. Picking and biting of the nails are a prominent cause in young children and nail biters. In most cases, when white spots appear on a single or a couple of fingers or toes, the most common cause is injury to the base (matrix) of the nail. When this is the case, white spots disappear after around eight months, which is the amount of time necessary for nails to regrow completely.
