J Cutan Aesthet Surg. 2011 Jan-Apr; 4(1): 58–60.
Abstract: Laugier–Hunziker syndrome (LHS) is an acquired, benign pigmentary skin condition involving oral cavity including lower lip in the form of brown black macules 1–5 mm in size, frequently associated with longitudinal melanonychia. There is no underlying systemic abnormality or malignant predisposition associated with LHS, and therefore the prognosis is good. Important differential diagnoses include Peutz Jeghers syndrome and Addison’s disease among other causes of oral and acral pigmentation.  PubMed Central.
