Nail dyschromias.
Nail dyschromias have a wide variety of presentation. There are numerous causes of discoloration of the nail affecting the nail plate, nail attachments, or the substance of the nail. The chromonychia may also be caused due to the exogenous deposition of pigments over the nail plate. Careful examination of the nail and few bed side tests may help in identifying the root cause of the nail dyschromia and many a times unravels some underlying systemic disorder too.
