What is Laugier-Hunziker syndrome?
Laugier-Hunziker syndrome is a harmless rare sporadic disorder that is characterised by flat brown marks on the lips and inside the mouth, and frequently brown stripes on the nails. It is important to distinguish it from Peutz-Jeghers syndrome, which has similar cutaneous features but also has associated gastrointestinal polyps.
