Unknown.
HistologyThis section has been translated automatically.
Hyperpigmentation of the epithelium, melanophages in the papillary body, no nevus cells.
Differential diagnosisThis section has been translated automatically.
See Table 1 under Melanonychia striata longitudinalis.
Differential diagnoses of diffuse oral mucosal and lip hyperpigmentation may be congenital (in the context of systemic diseases such as Peutz-Jeghers syndrome, McCune-Albright syndrome, LEOPARD syndrome or Name syndrome) or acquired (smoking, drug use or inflammatory processes).
Note: Although Laugier-Hunziker syndrome is defined as a benign disease without malignant potential, malignant melanoma should always be considered in differential diagnosis (Lambertini M et al. 2018).
