What is it about?
Transverse grooves with an arcuate margin matching the lunula have been known for years as Beau’s lines because of the endogenous temporary interference with nail formation some weeks after the precipitant. These may be on isolated diseased digits (trauma, in•ammation or neurological events) or generalized, re•ecting a systemic event, including malnutrition, cytotoxic agents, zinc deŽciency, surgery, or high fever.
