Overview
Beau's lines are deep grooved lines that run from side to side on the fingernail. They may look like indentations or ridges in the nail plate that could be a sign of stress. Beau's lines are the result of a temporary cessation of cell division in the nail matrix, and they are associated with many serious conditions.
Historical Perspective
This condition of the nail was named by a French physician, Joseph Honoré Simon Beau (1806–1865), who first described it in 1846.

Diagnosis
Physical Examination
Beau's lines should be distinguished from Muehrcke's lines of the fingernails. While Beau's lines are actual ridges and indentations in the nail plate, Muehrcke's lines are areas of hypopigmentation without palpable ridges.
Research
A researcher found Beau's lines in the fingernails of 6 divers following a deep saturation dive to a pressure equal to 335 meters of sea water, and in 2 of 6 divers following a similar dive to 305 meters.[1]
