Mentions: Half-and-half nail, also called Lindsay's nail, [Figure 1] is specific for renal failure. The distal 20–60% of the nail is red, pink or brown. The rest of the nail has a dull, whitish, ground-glass appearance. Muehrcke's lines (white arrow) are the smooth white bands that run parallel to the lunula across the width of the nail. Muehrcke's lines occur in patients with hypoalbuminemic states and disappear when the protein level normalizes. It is unusual to find both the nail changes in same patient. Muehrcke lines differ from Beau's lines, which are palpable, and Mees lines, which do not disappear on blanching.
