Mees' lines
Mees' lines (pronounced: /miːz/ lines), also known as leukonychia striata, are a clinical sign characterized by transverse white lines that run parallel to the lunula on the nail plate. They were first described by Dutch physician R.A. Mees in 1919.
Etymology
The term "Mees' lines" is named after the Dutch physician R.A. Mees, who first described this condition in 1919. The term "leukonychia striata" is derived from the Greek words "leuko" meaning white, "onyx" meaning nail, and "stria" meaning line.
Description
Mees' lines are transverse white bands that cross the nail plate. They run parallel to the lunula and are usually seen in all nails at the same time. The lines are caused by a temporary disruption in the production of the nail plate in the nail matrix. This disruption can be due to various systemic conditions, including severe illness, poisoning, or malnutrition.
Causes
Mees' lines can be caused by a variety of conditions, including:
