Leukonychia is whitening of the nail plate or nail bed. The classification into true, apparent, and pseudo-leukonychia is clinically important because each category has different causes, diagnostic tests, and treatments. Most white nails are benign; a systematic approach identifies the rare cases requiring systemic workup.
Leukonychia Classification and Causes
| Type | Location | Compression Test | Common Causes |
|---|---|---|---|
| True leukonychia (total) | Nail plate itself | White persists under compression | Hereditary (autosomal dominant); hypoalbuminemia; chemotherapy |
| True leukonychia (punctate) | Nail plate; white spots | Persists | Trauma to matrix (most common); manicure pressure; minor injury |
| True leukonychia (striate/transverse) | Nail plate bands | Persists | Arsenic toxicity (Mees lines); renal failure; cardiac arrest; chemotherapy |
| Apparent leukonychia (Terry nails) | Nail bed; proximal 2/3 white | Blanches (disappears) | Liver cirrhosis; congestive heart failure; diabetes; aging |
| Apparent leukonychia (Half-and-half nails) | Nail bed; proximal white, distal red-brown | Blanches | Chronic kidney disease (Lindsay nails) |
| Pseudo-leukonychia | Nail plate surface | Scrapes off | Onychomycosis (white superficial); nail polish residue |
Diagnostic Approach
| Presentation | First Step | If Abnormal |
|---|---|---|
| Punctate white spots, single nail | History of trauma; observe | Usually resolves in 3-6 months; no workup needed |
| Multiple white nails, all toenails | KOH preparation for onychomycosis; scrape superficial | Treat onychomycosis if confirmed |
| Terry nails (proximal 2/3 white, distal pink) | Liver function tests; albumin; cardiac workup | Treat underlying systemic condition |
| Half-and-half nails | BMP; renal function; creatinine | Nephrology referral if renal disease confirmed |
| Transverse white bands, multiple nails | Heavy metal screen; medication review; albumin | Arsenic/thallium screening if unexplained |

Doctor Answer
What are the different causes of leukonychia (white nails)?
Leukonychia has several distinct causes: true leukonychia from matrix damage causes white discoloration within the nail plate itself, most commonly from minor repetitive trauma. Apparent leukonychia — where the white comes from the nail bed rather than the plate — can indicate hypoalbuminemia (Muehrcke’s lines), liver cirrhosis (Terry’s nails), or chronic kidney disease. Fungal infection causes white superficial onychomycosis. I differentiate these through examination and targeted testing when systemic causes are suspected.
