II. Pathophysiology
- Abnormality of vascular nail bed
III. Causes
- Hypoalbuminemia (<2g/dl)
- Nephrotic Syndrome
- Cirrhosis
- Malnutrition
IV. Signs: Transverse Linear Nail Lesion
- Parallel, narrow horizontal (transverse) white lines at nail bed
- Lines do not move with Nail Growth (involves nail bed, not the nail plate)
- Lines disappear when nail plate is depressed
- Lines resolve with treatment of hypoalbuminemia (if that was the underlying cause)
