Acquired Punctate and Striate Leukonychia

Mees lines

The lines persist on blanching. They movement forward beyond the nail equally it grows. The nail plate is microscopically fragmented, and parakeratotic cells are nowadays. The disruption of boom growth causes the white lines. The distance of the lines from the cuticle at the proximal blast fold shows how long ago the illness or poisoning occurred.

Other conditions which nowadays with Mees lines include Hodgkin'south disease, leprosy and tuberculosis, chemotherapy, herpes zoster, renal and cardiac failure, and pneumonia.

Muehrcke's lines

These are specific transient double white lines which announced in hypoalbuminemia, when the albumin level dips below 2 g/dL. These disappear when the nail is fair-skinned by pressure. The lines also do not move forward with time. The phenomenon is confined to the nail bed, and is supposed to be the effect of edema nether the smash plate, putting pressure on the nail bed at localized points.

Total Congenital Hereditary Leukonychia

This condition presents with a marble-white advent of all the nails, and is commonly inherited in an autosomal dominant pattern. It involves the whole smash plate. The defect is one of the PLCD1 factor on chromosome iii, which encodes for the color and growth of the nail plate.

Acquired Full Leukonychia

In conditions such as diabetes, renal, and cardiac failure, renal stones, and Hodgkin's affliction, total white discoloration of the nails may occur.
