Beau lines are varying depths of grooves that run across the nail plate.[2][6] Generally all the nails are involved at the same level; though trauma may result in a single nail being affected.[2]
Causes include severe illness, chemotherapy, Raynaud disease, trauma, malnutrition, and pemphigus.[3][7] In some cases the cause remains unknown.[7] It may be seen in people with eczema or psoriasis.[8] The underlying mechanism involves disruption in nail growth.[3] As nails grow approximately 1 mm every 8 days, the distance the lines have moved indicate when the causative event occurred.[9] If multiple lines are present within the same nail it indicates multiple causal events.[10]
Treatment is directed at the underlying cause.[3] The lines will grow out and resolve without any specific measures.[11] They are relatively common.[5] They are named after the French physician, Joseph Honoré Simon Beau, who first described them in 1846.[1][9]
